## Long description

CBO SFP2121BU2MK is a 2 m singlemode fiber patch cable with LC to LC connectors and a yellow outer jacket. The cable uses bending‑insensitive G.657.A1 fiber and compact LC terminations to provide reliable optical connections for patching and interconnection in telecom and data network environments. Designed for use in racks, cabinets and wall panels, it simplifies identification and routing with its standardized yellow color and slim connector form factor.
Advantages
The 2 m length offers a balance between reach and cable management in patching fields. G.657.A1 bending‑insensitive fiber reduces performance degradation in tight routing scenarios and allows closer bends near equipment and panels. LC to LC connectors deliver compact duplex connections suited to high‑density panels while the yellow jacket enhances visibility and standard compliance for singlemode links.
Suitable for
 Patching between optical distribution frames, switches and transceivers
 Connections inside server racks and network cabinets
 Interconnections on wall panels and fiber outlets
 Short interconnect runs in data centres and telecommunication rooms
Key specifications
 Fiber type: singlemode, bending‑insensitive G.657.A1
 Length: 2 m
 Connector A: LC duplex
 Connector B: LC duplex
 Jacket colour: yellow
 Application: indoor patching and interconnection
How to use
Route the patch cable between the two LC ports to be connected, taking care to follow existing cable management paths and strain relief practices. Align the duplex LC connectors with the adapter or transceiver ports and insert until a tactile click confirms engagement. Avoid tight bends below the specified minimum bend radius for G.657.A1 fiber where possible and secure excess length to prevent stress on the connectors and adapters.
Usage recommendations
Store and handle the cable in a clean environment, keep connector end faces covered until installation, and use compressed air or approved cleaning tools to remove dust before mating. For repeated moves or frequent re-patching, inspect connector end faces and replace the cable if physical damage or persistent loss is observed.
