Extralink LC/UPC - LC/UPC Singlemode Duplex 3mm Patch Cable, 5m

Extralink LC/UPC - LC/UPC single-mode duplex patchcord, 3 mm jacket, 5 m length, designed for low-loss optical connections in data and telecommunication networks. The cable uses G.652D single-mode fibre suitable for FTTH and campus cabling, with LC/UPC connectors on both ends in a duplex configuration. This patchcord is intended for short-distance interconnects between active equipment, patch panels and terminal devices where consistent single-mode performance and compact LC connectors are required.

Advantages

The Extralink patchcord offers low insertion loss and high return loss consistent with LC/UPC polished connectors and G.652D fibre, ensuring reliable signal transmission. Its 3 mm jacket provides mechanical protection while remaining flexible for routing in cabinets and conduits. The duplex LC format saves rack space and simplifies identification of paired fibres. The product is compatible with standard single-mode equipment and FTTH terminations.

Suitable for

• Connecting switches, media converters and transceivers in data centres and network closets
• Interfacing patch panels and fiber distribution frames
• FTTH connections between OLT and ONU/ONT devices
• Short-run campus and metropolitan single-mode links

How to use

Route the patchcord between equipment ports, patch panels or termination boxes ensuring gentle bends and avoiding sharp kinks that can increase attenuation. Insert each LC connector into the corresponding LC receptacle until it clicks; ensure correct polarity for transmit/receive pairs. When disconnecting, press the latch on the LC connector and pull straight out. For installations in cabinets or trays, secure excess length using cable management accessories to prevent strain on connectors and fibre.

Recommendations

Store and handle the patchcord in a clean environment to avoid contamination of connector end-faces; use dust caps when connectors are not mated. Clean connector end-faces with appropriate fiber cleaning tools before connecting. Maintain minimum bend radius recommended for 3 mm jacketed single-mode cable and avoid tensile loads on the connectors.
