CS/UPC to LC/APC Uniboot Patch Cord

What Is a CS/UPC to LC/APC Uniboot Patch Cord?

A CS/UPC to LC/APC Uniboot Patch Cord is a hybrid duplex fiber cable used to connect SENKO CS® VSFF interfaces to LC/APC equipment, ODFs, distribution frames or optical network systems.

The CS® side is suitable for high-density data center ports, VSFF patch panels and next-generation transceiver-related cabling. The LC/APC side provides angled-polish connectivity for APC-based equipment, FTTH/ODN distribution systems and optical networks where lower back reflection is required. This makes the cable especially useful when customers need to bridge new CS® VSFF connectivity with existing LC/APC infrastructure.

Product Advantages

High-Density VSFF to LC Connectivity

The SENKO CS® connector side helps support high-density Base-2 optical connectivity, while the LC/APC side allows the cable to connect with widely deployed APC-based LC equipment. This makes the cable practical for projects where new high-density CS® interfaces need to be integrated with existing LC/APC infrastructure.

Cleaner Cable Management with Uniboot Structure

Compared with traditional duplex zipcord patch cords, the 2.0mm round duplex uniboot structure helps reduce cable congestion and improves cable routing in high-density patch panels, racks and cabinets.

Factory-Tested IL/RL Performance

Each cable can be supplied with a label showing the serial number, cable length, insertion loss and return loss values. The attached 5m sample test data shows insertion loss values from 0.05 dB to 0.14 dB and return loss values from 54.1 dB to 61.7 dB.

Custom Built for Project BOMs

BWNFiber can support custom cable length, G.657A1 or G.657A2 fiber options, 2.0mm standard cable, evaluated compact cable structures, LSZH jacket, custom polarity, boot color, pull-tab length, product label, OEM packaging and 100% IL/RL test report before shipment.
