## Long description

BlueOptics SFP2121BU5MM is a 5 m singlemode fiber optic patch cable with LC to LC termination and G.657.A1 bend‑insensitive fiber. Designed for low insertion loss and reliable signal transfer, this yellow singlemode patch lead connects SFP transceivers, switches and other networking equipment in telecom, data center and campus environments. The compact LC connector footprint and colour-coded jacket simplify installation and cable management in dense racks and confined spaces.
Advantages
This fiber patch cable features bend‑insensitive G.657.A1 fiber to reduce attenuation in tight bends and cable routing paths. The LC to LC connections provide a compact duplex interface suitable for modern SFP transceivers. A 5 m length covers typical patching distances inside racks and between adjacent equipment cabinets, while the yellow jacket offers quick visual identification for singlemode links. The cable is manufactured to provide consistent insertion loss, low back reflection and stable performance for optical links.
Suitable for
 Patching between SFP modules and network switches or routers
 Interconnecting equipment in data centers and server rooms
 Campus and enterprise backbone links requiring singlemode fiber
 Tight-space installations where LC connectors and bend‑insensitive fiber are needed
Key specifications
 Fiber type: Singlemode, G.657.A1 bend‑insensitive
 Connector type: LC to LC duplex
 Length: 5 m
 Jacket colour: Yellow
 Application: SFP transceiver patching, telecom and data center links
How to use
Inspect connectors for cleanliness before connecting; clean endfaces if required using approved fiber cleaning tools. Align and insert the LC connectors into the corresponding SFP transceiver and switch/router ports until they click into place. Route the cable to avoid sharp bends tighter than the minimum bend radius recommended for G.657.A1 fiber, and secure the cable using appropriate management accessories to prevent strain on connectors. To disconnect, depress the LC latch and gently withdraw the connector.
Usage recommendations
Store the cable coiled without tight loops, avoid mechanical stress on connectors, and perform periodic inspection of connector endfaces to maintain low insertion loss and reliable optical performance.
