A ceramic-ferrule SC fiber connector engineered for ≤0.2dB insertion loss, >60dB return loss, and 1,000 mating cycles — so every FTTH drop, data center trunk, and security backbone holds the line.
Picture a network link that never lets you down: no dropped signal at 2am, no truck roll over a dirty ferrule, no angry message from a customer whose video call keeps freezing. That is the promise behind every SC fiber connector COBTEL builds.
A fiber network is only as strong as its weakest connection point, and that single truth is why network engineers, system integrators, and telecom buyers keep coming back to the COBTEL SC APC fiber connector for every link that has to work the first time, and every time after that. This sc fiber optic connector pairs a precision ceramic ferrule with an 8-degree angled polish that cuts back reflection and pushes return loss above 60dB, so your signal stays clean instead of bouncing noise back into the transmitter.
Every fiber SC connector we ship arrives with a dust-proof cap over the ferrule, a flame-retardant housing around the body, and a long tail sleeve that shrugs off bending and cable strain during a busy installation day. Whether you run FTTH drops to homes, trunk cables inside a data center, backbones for a citywide camera network, or precision links inside a test lab, this sc connector fiber optic solution gives you a stable, repeatable mate on cycle one and on cycle one thousand.
Buyers across telecom carriers, systems integrators, and equipment manufacturers choose this fiber optic sc connector because the numbers on the datasheet match the numbers in the field, shipment after shipment. If your project calls for a fiber optic connector sc apc that holds its specification through real-world heat, cold, dust, and constant plugging and unplugging, you have found the right supplier — and the right connector — in one place.
Most buyers do not choose a connector because of a single spec on a datasheet. They choose it because a supplier answers the phone, ships on time, and stands behind the part after the invoice is paid. That is the standard COBTEL holds itself to on every sc fiber connector order, from a five-piece engineering sample to a container-load production run, and it is why so many of our customers place a second order without ever requesting a second quote.
B2B buyers do not shop for a connector — they shop for a solution to a network they are responsible for. Here is where this SC fiber connector earns its keep.
Fiber-to-the-home projects live or die on connector quality. An sc apc connector ftth fiber deployment demands consistent low loss across thousands of terminations, and our sc fiber connectors give ISPs and contractors a drop-in solution for ONT installs, distribution boxes, and splice closures.
One weak sc fiber optic connector buried in a dense patch panel can slow an entire rack. We supply duplex sc fiber connector and single mode fiber sc connector assemblies rated for high-density cross-connects and long trunk runs.
CCTV backbones depend on multimode fiber sc connector hardware that keeps working in outdoor junction boxes, through temperature swings, and beside vibrating rooftop equipment — so the picture never freezes when it matters most.
Test benches and factory automation lines use a fiber sc apc connector where signal drift of even a fraction of a decibel throws off a measurement. The ceramic ferrule protects signal integrity on noisy plant floors.
Cable operators rely on an apc sc fiber connector for the return-loss performance that keeps upstream noise out of the network — translating into fewer dropped video-on-demand sessions and steadier broadband speed.
Utility-scale solar sites run fiber for SCADA links across long, exposed distances. A green sc fiber connector, sealed against dust and shielded by its long tail sleeve, holds up in remote enclosures without a truck roll.
One Connector Family, Every Project on Your Desk. Most procurement teams juggle separate suppliers for telecom-grade parts, data center parts, and industrial parts, adding lead time and paperwork to every project. Because COBTEL manufactures the full range — from sc apc fiber connector and sc upc fiber connector to sc pc fiber connector, in both simplex and duplex sc fiber connector formats — one purchase order and one quality standard can cover an entire project instead of three separate ones.
Every sc fiber connector we manufacture is built around a high-quality ceramic ferrule, hand-selected for roundness and concentricity. This ferrule delivers stable data interchangeability, high insertion and extraction durability, and repeatable performance across a full 1,000 mating cycles, so your fiber sc connector reads the same on day one and on day one thousand.
Insertion loss stays at or below 0.2dB, and return loss stays above 60dB on every fiber sc apc connector that leaves our factory — less signal loss at every connection point, a longer usable link budget, and fewer amplifiers needed to make up for weak hardware upstream.
Every connector at both ends of the optical fiber ships with a dust-proof cap that shields the ferrule end-face from scratches, oil, and dust during shipping and installation — protecting the sc connector fiber from the single most common cause of field failures: a dirty end-face.
The housing on this sc fiber optic connector uses high-precision, flame-retardant components that hold tight tolerances for consistent optical alignment. Paired with a spring rated for high compressive strength, it maintains firm, even contact pressure across its full service life.
A long tail sleeve wraps the fiber exit point in a tough, bend-resistant, unbreakable jacket that will not crack, deform, or shed material even under repeated flexing — saving installers from the slow failure mode of a connector that looks fine outside while the fiber inside is already damaged.
We manufacture this connector as an sc pc fiber connector, sc upc fiber connector, and sc/apc fiber connector, so you order the exact polish your network calls for. PC and UPC use a flat or slightly domed end-face; APC uses an 8-degree angled polish for the lowest possible back reflection. These three types must never be mixed or mated together.
A green sc fiber connector marks APC polish at a glance, while blue housings mark PC and UPC types. On a job site with thousands of sc fiber optic connectors to place correctly, this fast visual check prevents mismatched connections.
Every fiber sc connector from COBTEL is tested before packing, not spot-checked after a complaint, so the insertion loss and return loss numbers on your incoming inspection report match the numbers on our outgoing test report — the difference between a one-time order and a repeat purchase order.
Buyers searching for fiber connector types sc, or browsing a distributor catalog under fiber optic sc connectors, usually land on the same three-way split: PC, UPC, and APC polish, each available in simplex or duplex sc fiber connector format, and in sc to sc fiber connector patch cords for linking two SC ports directly. COBTEL stocks the full spread of fiber sc connector types, including sc p fiber connector and sc upc fiber optic connector variants, plus sc single mode fiber connectors for long-haul runs and sc mm fiber connectors for shorter multimode links — one purchase order can cover every fiber SC connector type your project needs.
Some technical sheets list this part as a fiber sc apc 9 connector, referencing an alternate angle notation used on older datasheets, but COBTEL's current sc/apc fiber connector and sc/upc fiber connector lines both follow today's industry-standard 8-degree APC angle for the lowest possible back reflection.
Whether your project calls for a single sc fiber connector on a simplex jumper or a sc duplex fiber connector and duplex sc fiber optic connector pair on a transceiver patch cord, COBTEL builds both from the same ferrule and housing tooling. A fiber sc to sc connector patch cord, made by mating two of these connectors to opposite ends of the same fiber, is one of the most common assemblies we ship, alongside standard fiber sc connectors sold loose for field termination. This sc type fiber connector, and every fiber connector sc apc variant built from it, goes through the same 100% optical test before packing, so a sc type fiber optic connector pulled from any box on the shelf performs the same as the one measured on our test bench.

COBTEL welcomes OEM orders and custom sc fiber connector types built to your drawings, print specifications, or an existing reference sample you send us. Ship us your sample or CAD file, and our engineering team confirms feasibility within one business day — not a week of silence.
Our Dongguan facility runs dedicated fiber connector assembly lines supported by automated polishing machines, precision injection molding, and in-line optical test stations that check every finished sc fiber optic connector before it reaches a packing box. Multi-fiber polishing jigs process dozens of ferrules per cycle, holding gloss, curvature, and apex offset within strict tolerance on every run.
Each connector passes through end-face geometry testing plus insertion loss and return loss verification, so the numbers that leave our factory match the numbers you measure on yours. Our after-sales team responds to technical questions and warranty claims within one business day, backed by a standard 12-month warranty against manufacturing defects.
COBTEL operates under an ISO 9001 certified quality management system, and our fiber optic sc connector line meets RoHS and CE requirements for global markets, so paperwork never holds up a shipment or a customs clearance. Independent end-face geometry inspection and 100% optical testing back every batch we ship, and we provide test reports and compliance documentation on request.
Telecom carriers, systems integrators, and OEM brands across more than 40 countries currently specify COBTEL connectors on their approved vendor lists — a track record built one consistent, repeatable shipment at a time.
Certifications matter because they remove guesswork from your own compliance paperwork, but they only tell part of the story. The rest of the story is written every day on our test bench, where each finished sc fiber connector is measured against the same insertion loss and return loss thresholds before it ever leaves the building, so the certificate in your file and the connector in your hand always agree.
What is an SC fiber connector?
An SC fiber connector, short for Subscriber Connector, is a push-pull style fiber optic connector with a square housing and a ceramic ferrule that holds the fiber end-face in precise alignment. It ranks among the most widely used connector types in telecom, data center, and enterprise networks because of its low insertion loss and simple, snap-in installation.
What does SC/APC mean on a fiber connector?
SC/APC means the connector uses an SC-style housing paired with an APC, or Angled Physical Contact, polish. The ferrule end-face is polished at an 8-degree angle instead of flat, which redirects reflected light away from the fiber core and produces far lower back reflection than PC or UPC polish types — exactly why FTTH and CATV networks favor it.
What are the standard SC fiber connector dimensions?
The SC connector uses a standard 2.5mm ceramic ferrule housed inside a rectangular push-pull body, matching the same footprint used across the fiber optic industry, so it fits standard SC adapters, patch panels, and transceiver ports without any modification.
How do I install an SC fiber connector correctly?
Basic sc fiber connector installation calls for a fiber cleaver, a termination kit matched to your connector style (adhesive, mechanical splice, or crimp), polishing film or a polishing puck, and a fiber scope for end-face inspection. After termination, polish the end-face in a figure-eight motion, then inspect under the scope to confirm a clean, defect-free finish before mating.
What is the typical SC fiber connector price range?
Pricing depends on polish type, fiber mode, order volume, and any custom sample or tooling work involved. Bulk B2B orders typically bring per-unit pricing down significantly compared to small retail-style purchases, and COBTEL offers tiered pricing from qualification samples through full production container loads.
What SC fiber connector types does COBTEL manufacture?
We manufacture SC/PC, SC/UPC, and SC/APC variants, in both single mode and multimode fiber SC connector versions, plus simplex and duplex SC fiber connector configurations to match nearly any network design.
How is an SC/APC connector different from an SC/UPC connector?
An SC/APC connector uses an 8-degree angled ferrule polish for very low back reflection, which is why FTTH and CATV networks specify it so often. An SC/UPC connector uses a flat, ultra-polished end-face suited to general single mode links where back reflection matters less. The two polish types cannot be mated together without damaging the end-face.
How does COBTEL compare to brands like Corning SC fiber connectors?
Corning SC fiber connectors and Corning SC APC fiber connectors carry strong name recognition across the industry. COBTEL manufactures to the same SC footprint and the same optical performance benchmarks, so our connectors work as a drop-in equivalent while giving B2B buyers a manufacturer-direct sourcing option, custom OEM support, and more flexible order volumes.
What is the mating durability of COBTEL SC fiber connectors?
Every connector we ship is rated for 1,000 mating cycles while holding insertion loss at or below 0.2dB and return loss above 60dB, meeting standard telecom-grade durability requirements for repeated connect-and-disconnect use.
Can SC fiber connectors be used with both single mode and multimode fiber?
Yes. COBTEL supplies both single mode fiber SC connector and multimode fiber SC connector versions, along with SM SC fiber connectors and SC MM fiber connectors options, so you can match ferrule and polish specification to your exact fiber type.
What is the difference between an SC connector and an SC adapter?
An SC fiber connector terminates the end of a fiber cable and plugs into a port, while an SC fiber adapter connector — more commonly called an SC adapter or coupler — is the sleeve or bulkhead component that aligns and joins two SC connectors together, typically mounted in a patch panel or wall plate.
Are COBTEL SC fiber connectors compatible with standard SC adapters and patch panels?
Yes. Every SC fiber optical connector we manufacture follows standard SC industry dimensions, so it seats correctly in any standard SC adapter, patch panel, wall plate, or transceiver port without requiring a special adapter or modification.
What is the definition and meaning of "SC" in SC fiber connector?
The SC fiber connector definition traces back to "Subscriber Connector," sometimes also read as "Standard Connector." Either way, the sc fiber connector meaning refers to the same part in practice: a square, push-pull fiber connector with a ceramic ferrule, used across telecom, data center, and enterprise networks for its low loss and simple, tool-light installation.
