Description
The SC to LC
Singlemode Fiber
Patch Cord That
Never Lets You Down
Stop losing data. Stop replacing cables. The COBTEL SC LC singlemode fiber patch cord delivers ≤0.2 dB insertion loss, ≥50 dB return loss, and a Grade A fiber core - backed by high-precision polishing and 100% factory testing. This is the fiber optic patch cord SC LC that data centers, telecom rooms, and security networks trust every day.
One SC LC Fiber Patch Cord.
Every Network. Zero Compromise.
Your network is only as strong as its weakest connection. The COBTEL SC to LC fiber patch cord is built so that connection is never the weak point. With an LC/UPC connector on one end and an SC/UPC connector on the other, this fiber optic patch cord SC LC bridges two of the most widely used fiber port types in the world - cleanly, reliably, and with signal integrity that meets or exceeds telecom-industry benchmarks.
The core is 9/125 singlemode glass - Grade A - with insertion loss held at ≤0.2 dB and return loss at ≥50 dB. Those numbers are not marketing estimates. They are verified on every single unit before it leaves the production floor. If a cable does not hit the standard, it does not ship. That discipline is exactly why network engineers across data centers, telecom rooms, and security monitoring facilities choose this sc lc singlemode fiber patch cord again and again.
The 2.0 mm LSZH-jacketed duplex cable carries two fibers side by side - one for transmit, one for receive - giving you simultaneous bidirectional communication over a single assembly. The jacket material is low-smoke, zero-halogen, and flame-retardant. In a data center or public building where fire safety codes matter, that is not optional. It is essential.
Whether you are stocking a warehouse for resale, installing new infrastructure in a carrier hotel, or sourcing sc lc fiber patch cords for a large-scale enterprise deployment, COBTEL gives you factory-direct pricing with no compromise on the build quality that professional-grade networks demand.
6 Reasons This Fiber Patch Cord SC LC
Outperforms Every Other Option
Plenty of suppliers sell a duplex fiber optic patch cord. Very few deliver one that holds its performance through thousands of mating cycles, hot server rooms, and years of daily use. Here is what separates COBTEL from the crowd.
Grade A Fiber Core with Bend-Insensitive Design
The 9/125 singlemode glass core is precision-doped to maximize total internal reflection. It is bend-insensitive - meaning tight cable routing inside crowded racks does not cause signal degradation. Other budget cables break down at bends. This one does not.
Ceramic Ferrule: High Return Loss, Low Insertion Loss
Both the LC and SC connectors use precision ceramic ferrules. Ceramic maintains its geometry over thousands of mating cycles far better than plastic alternatives. The result is consistent ≤0.2 dB insertion loss and ≥50 dB return loss - every time, not just on day one.
High-Precision UPC Polishing - End-Face Tested
Every connector end-face goes through automated precision polishing on calibrated polishing machines. After polishing, each end-face is individually inspected under a fiber scope. Geometry, gloss, and cleanliness are all verified before the cable is released. You receive a cable that has passed, not one that might pass.
LSZH Jacket: Fire Safe & Eco-Friendly
The jacket is Low Smoke Zero Halogen (LSZH) - flame-retardant, low-toxic emissions, and halogen-free. It resists moisture, acid, and alkali. This material is required by fire codes in data centers and public infrastructure worldwide. It is also genuinely eco-friendly, which matters to forward-thinking procurement teams.
Aramid Yarn Strength Member - Pull-Resistant
Inside the cable, aramid yarn fibers wrap the glass core. Aramid has high tensile strength, low elongation, and fatigue resistance. When cables get pulled during installation or maintenance, the aramid absorbs the force - not the glass. That one feature prevents more field failures than any other design choice.
Long Boot Sleeve - 360° Bend Protection
The long tail sleeve at each connector extends protection several centimetres back from the ferrule face. This integrated design stops the most common installation damage: the sharp bend that happens right at the connector body when cables are dressed under tension. Integrated, non-deformable, and built to last.
Inside the SC LC Singlemode Fiber Patch Cord:
Every Part Built to a Higher Standard
Great performance starts with great components. Every part in this lc sc singlemode fiber patch cord is selected for a specific reason. Here is what is inside the cable you are buying.
SC/UPC Duplex Connector
The SC end uses a square push-pull housing made from high-precision, flame-retardant polymer. A 2-to-1 duplex conversion clip locks both SC ferrules into a single body for clean, space-efficient connections. Inside, two precision ceramic ferrules sit on calibrated springs that maintain consistent contact force through every mating cycle. Protective dust caps are included and stay on during transport to keep the end-face clean.
Compatible with all standard SC/UPC-accepting transceivers, patch panels, and switches from Cisco, Juniper, Huawei, ZTE, and major telecom OEMs.
LC/UPC Duplex Connector
The LC end features the industry's most compact and widely deployed small-form-factor connector. The blue LC duplex body houses two 1.25 mm ceramic ferrules with a latch-lock mechanism that clicks positively into SFP and SFP+ transceivers, LC panels, and ODF frames. High-precision flame-retardant components ensure the housing geometry stays consistent even after thermal cycling in hot environments.
The LC connector's smaller footprint compared to SC makes it the preferred choice for high-density 1U patch panels, where port count per rack unit is critical.
9/125 Singlemode Glass Fiber Core
The heart of every fiber optic patch cord lc sc is the fiber glass itself. COBTEL uses Grade A 9/125 singlemode glass - precision-doped with a controlled refractive index profile. This enables maximum total internal reflection across long distances with minimal attenuation. Bend-insensitive design means signal integrity holds even when the cable is routed through cable trays with tight radius bends.
Aramid Yarn & LSZH Duplex Jacket
Surrounding the fiber core, aramid yarn strength members provide high tensile resistance, low elongation, and fatigue resistance. The outer LSZH duplex jacket - 2.0 mm outer diameter - is low-smoke, zero-halogen, flame-retardant, eco-friendly, and resistant to moisture, acid, and alkali. The yellow color coding is the international standard for OS2 singlemode fiber, making polarity identification instant in any data center environment.
A Duplex Fiber Optic Patch Cord
That Survives the Real World
Most fiber cables fail at the same two points: the connector ferrule and the jacket under mechanical stress. COBTEL has addressed both in this sc lc fiber patch cord through material selection and structural design, not just specification claims.
The LSZH jacket is not just a safety requirement. It is a structural upgrade. LSZH material resists compression and tension better than standard PVC jackets. It does not crack or become brittle in cold environments down to −20°C. It does not soften or deform in hot server rooms up to +85°C. That operating range covers every real-world installation scenario from outdoor telecom cabinets to air-cooled data halls.
The aramid yarn inside acts as a shock absorber for pulling forces. When installation crews pull cables through conduits or dress them across cable managers, the aramid carries the load. The glass fiber is never under strain. That is why this sc lc singlemode fiber patch cord survives the installation process that kills inferior cables before they ever carry a single bit of traffic.

How Every Fiber Optic Patch Cord LC SC
Gets Made - and Tested
COBTEL does not guess at quality. Every step of the manufacturing process - from raw fiber selection to finished-cable inspection - follows documented procedures. This is what carrier-grade quality actually means in practice.
Grade A Raw Material Selection
Every production run starts with Grade A 9/125 singlemode fiber glass. Material lots are tested on arrival before entering production. Off-spec fiber never enters the assembly line.
Precision Ferrule Assembly
Ceramic ferrules are assembled on calibrated fixtures that control insertion depth and concentricity. Spring tension and housing geometry are verified for each connector body before fiber insertion.
High-Standard Production Technology
COBTEL uses high-standard production technology specifically developed to eliminate the two most common fiber patch cord failures: internet disconnection events and data packet loss. Adopting controlled polishing parameters and automatic assembly reduces human error in every step.
High-Precision Automated Polishing
End-faces are polished on precision automated equipment that controls all parameters - craftsmanship, surface gloss, geometry, and ferrule tip curvature radius - to meet or exceed TIA-455 and IEC 61755 requirements for UPC polished connectors.
End-Face Microscopy Inspection
After polishing, every connector end-face is inspected under a fiber scope. Surface defects, scratches, chips, and contamination are rejection criteria. No connector with a visual defect proceeds to optical testing.
100% Optical Insertion Loss & Return Loss Testing
Every finished sc to lc fiber patch cord is tested individually with calibrated optical loss test sets. Insertion loss and return loss values are measured and compared against specification. Only cables that pass ship. No batch sampling. No shortcuts.
