PRODUCT OVERVIEW

The LC UPC to LC UPC Duplex OS2 Single Mode Fiber Patch Cable features 

high-precision LC connectors on both ends with UPC polish, designed for 

high-speed optical network connectivity in telecommunications and data 

center environments. Constructed with bend-insensitive G.657.A1 fiber 

(fully compatible with G. 652.D), it offers low insertion loss, 

high return loss, and excellent long-term durability.

KEY FEATURES

Low Insertion Loss: Ceramic ferrule ensures insertion loss ≤ 0.3dB.

Bend-Insensitive Fiber: G.657.A1 fiber enables tight bend radii for neat management.

Flame-Retardant Jacket: Riser (OFNR) jacket rating for safe indoor deployment.

High Reliability: Standardized durability exceeding 1000 mating cycles.

Duplex LC to LC OS2 Bend-Insensitive Fiber Patch Cord

A duplex LC-to-LC assembly on OS2 single-mode bend-insensitive fibre. The bend-insensitive profile is what makes this cord worth specifying: standard single-mode fibre loses light sharply below a 30 mm bend radius, while the bend-insensitive grade holds its loss down to roughly 10 mm, which removes the most common cause of unexplained link failures in dense racks.

Construction & Materials

Two OS2 9/125 µm bend-insensitive fibres run in a zip-cord jacket and terminate in 1.25 mm LC/UPC ferrules. The fibre meets the G.657.A2 bend specification, so it can be routed through tight cabinet corners, coiled in a small splice tray, or dressed behind a deep patch panel without added attenuation. The duplex clip fixes the pair at the 6.25 mm transceiver pitch.

Key Features

• G.657.A2 bend-insensitive fibre holds loss down to a 10 mm bend radius
• Suited to long-reach 10G/40G/100G single-mode links and PON routes
• Low-loss LC/UPC ferrules with a typical IL of ≤0.15 dB
• 100% factory end-face inspection and IL/RL test report supplied with every batch
• Custom lengths, breakout counts, jacket colour and OEM printing available

Typical Applications

• Data centre cross-connects and top-of-rack patching
• Telecom central office and ODF termination
• FTTx access networks and subscriber drop panels
• Industrial and campus backbone cabling where bend loss matters

Specifications

• Insertion loss: ≤0.30 dB (typical), ≤0.50 dB (max) for multimode assemblies
• Return loss: ≥50 dB (UPC), ≥60 dB (APC)
• Operating temperature: −40 °C to +75 °C
• Durability: ≥500 mating cycles to IEC 61300-3-2

Selection Notes

Choose bend-insensitive fibre for any run that has to turn a tight corner, and especially for cabinets that are patched and re-patched often — the fibres that fail in service are almost always the ones bent beyond their limit during a routine change. Note that bend-insensitive fibre is backward compatible with standard G.652.D, so it can be mixed into an existing single-mode link without penalty. For PON deployments, confirm the split ratio and total link budget before fixing the cord length.

FAQ

Can you supply this assembly in custom lengths and colours? Yes. Huifiber builds patch cords to order in any length from 0.5 m to 50 m, with a choice of jacket colour, boot type and printing. Send us the connector pair, fiber type and length and we will confirm the price within 48 hours.

Do you provide test reports? Yes. Every batch ships with insertion loss and return loss test data, and we can supply an interferometric end-face report for single-mode assemblies on request.

What is the minimum order quantity? Standard configurations ship from 100 pieces. Mixed-model orders can be combined to reach the MOQ.
