The LC to LC UPC Duplex Single Mode Fiber Optic Patch Cord is designed for reliable high-speed optical signal transmission in FTTH, telecom, CATV, data center, and enterprise network applications. Manufactured with G657A1 bend-insensitive fiber, this patch cord provides improved flexibility and enhanced bending performance compared to standard G652D fiber, making it ideal for high-density cabling environments and limited installation spaces.
Equipped with precision LC/UPC connectors and high-quality ceramic ferrules, the cable delivers low insertion loss, high return loss, and stable optical performance for long-term network reliability. The duplex structure supports bidirectional data transmission, while the 2.0mm cable design offers a good balance between flexibility and mechanical durability.
The cable jacket is available in LSZH or PVC material to meet different installation requirements. LSZH jackets are suitable for indoor environments requiring low smoke and halogen-free performance, while PVC jackets provide excellent mechanical protection for general applications.
Each patch cord undergoes strict factory testing to ensure stable optical characteristics, excellent interchangeability, and consistent quality before shipment. Custom cable lengths, connector combinations, polishing types, and OEM labeling are also available for project and distributor requirements.
Suitable applications include:
FTTH and FTTx networks
Data centers and server rooms
Optical distribution frames (ODF)
Telecom transmission systems
CATV and broadband networks
