What Is an SN/UPC to LC/UPC Uniboot Patch Cord?
An SN/UPC to LC/UPC Uniboot Patch Cord is a hybrid duplex single-mode fiber cable that connects SENKO SN® VSFF interfaces to standard LC/UPC duplex ports.
The SN® connector side is designed for compact, high-density optical connectivity, while the LC/UPC side supports existing single-mode data center, telecom, and optical distribution equipment. This makes the cable useful for projects where customers need to connect next-generation SN® VSFF patching systems with established LC/UPC infrastructure.
This product is designed for high-density Base-2 optical connectivity, compact patching, easier cable routing, and reduced cable congestion.
SENKO SN® VSFF Connector to Standard LC/UPC Infrastructure
Bridge compact next-generation SN® VSFF ports with widely deployed LC/UPC equipment without a full infrastructure refresh.
The SENKO SN® connector is a Very Small Form Factor (VSFF) duplex optical connector that enables significantly higher port density than traditional LC duplex connectivity. By pairing SN®/UPC on one side with LC/UPC on the other, this uniboot patch cord lets network teams:
- Deploy high-density SN® patching in new racks or panels
- Retain existing LC/UPC switches, servers, and transceivers
- Reduce cable bulk with a 2.0mm round duplex uniboot jacket
- Simplify switch-to-switch and switch-to-server cabling
This is especially valuable in 400G/800G data center builds, Base-2/Base-8 migration, and space-limited high-port-count patch panels.

Product Advantages
Compact SN® VSFF to Standard LC/UPC Connectivity
The SN® side supports compact VSFF duplex connectivity, while the LC/UPC side connects to standard LC-based single-mode equipment. This allows network teams to introduce SN® high-density patching without replacing all existing LC/UPC infrastructure.
Cleaner Cable Routing in Dense Racks
The 2.0mm round duplex uniboot cable structure helps reduce cable congestion compared with traditional duplex zipcord patch cords. This is useful in racks where airflow, cable routing, port access, and patching visibility are important.
Suitable for 400G / 800G Cabling Environments
This patch cord is designed for high-density optical connectivity and can be used in 400G / 800G data center cabling environments, especially where compact Base-2 links, high-port-count panels, and equipment-side LC/UPC connections need to be matched.
Factory-Tested IL/RL Performance
Each cable can be supplied with a production label showing serial number, connector type, length, insertion loss, and return loss. The sample label format shows channel-level IL/RL data, including insertion loss values such as 0.12 dB, 0.20 dB, 0.07 dB, and 0.14 dB, with return loss values from 53.1 dB to 55.5 dB.
Custom Built for Project BOMs
BWNFiber can support custom length, polarity, label, boot color, packaging, private label options, and 100% IL/RL test reports before shipment. G.657A1 is standard, while G.657A2 and compact cable structures can be evaluated based on project requirements.
Base-2 / Base-8 Migration Support
Modern data centers are moving toward higher-density optical architectures. The SN® connector is optimized for Base-2 optical links, while Base-8 MPO/MTP systems remain common for parallel 400G/800G transceiver connectivity.
This SN/UPC to LC/UPC Uniboot Patch Cord helps during migration by:
- Connecting Base-2 SN® breakout ports to LC/UPC endpoint equipment
- Supporting compact front-panel patching in high-port-count racks
- Reducing cable congestion when scaling from Base-8 trunking to Base-2 server links
- Providing a clean upgrade path for hyperscale and cloud facilities
BWNFiber also supplies MPO/MTP trunk cables, SN® cassettes, and LC/UPC breakout panels to support complete migration designs.
