## Long description

CBO Fiber Optic Cable SFP2121BU10MK is a 10 m single-mode patch cable with LC connectors and a blue outer sheath. It is designed to link network devices that use LC ports, providing low-loss optical transmission for data links and telecom applications. The cable is intended for short runs inside racks, between patch panels, switches and SFP transceivers where single-mode performance and compact LC terminations are required.
Advantages
The single-mode construction ensures low attenuation and stable signal quality over the 10 m length, while LC connectors provide a compact duplex interface compatible with many transceivers and patch panels. The blue sheath offers easy visual identification of the cable type in structured cabling environments. The product is manufactured to industry connector standards to ensure reliable mating and repeatable performance in data centre and telecom installations.
Suitable for
 Interconnects between patch panels and network switches
 Connecting SFP/SFP+ single-mode transceivers to fibre ports
 Short single-mode runs within racks or server rooms
 Telecom and carrier access where LC duplex terminations are used
Key specifications
 Length: 10 metres
 Mode: single-mode (SM)
 Connector type: LC duplex (both ends)
 Outer sheath colour: blue
 Typical use: patch cable for optical data links and telecom equipment
How to use
Route the cable following standard cable management practices to avoid tight bends and mechanical stress. Clean LC connector endfaces before mating to minimise insertion loss and back-reflection. Insert each LC connector into the corresponding duplex LC port until it clicks; ensure correct polarity for transmit and receive channels. When disconnecting, depress the latch and pull the connector straight out to avoid damaging the ferrule or port.
Usage recommendations
Store and handle the cable to prevent kinks and avoid bend radii smaller than the manufacturer’s specified minimum. Use dust caps when connectors are not in use and perform periodic endface inspection in environments that demand low optical loss and high reliability.
