Fibre optic cable BlueOptics SFP2121BU2MS LC G.657.A1 2 m Yellow

The BlueOptics SFP2121BU2MS LC fibre optic cable is a 2 m single-mode patch cable designed for reliable high-speed data transmission in network environments. Compliant with G.657.A1 specifications and featuring a 9 µm core diameter, this yellow cable provides low attenuation and optimized bend performance for installations where space and cable routing impose tight radii. LC connectors on both ends ensure secure mating with SFP transceivers, switches and patch panels that accept LC interfaces.

Advantages

This 2 m cable offers predictable optical performance with standardised single-mode characteristics and low insertion loss. G.657.A1 compliance improves bend tolerance compared with older single-mode types, reducing signal loss in constrained routing scenarios. The LC connector format provides a compact footprint for high-density racks and patch panels, while the yellow jacket improves visual identification within structured cabling systems.

Suitable for

• Connecting SFP transceivers to switches and routers with LC ports
• Patch panel to network device links in data centres and wiring closets
• Environments requiring improved bend performance and compact routing
• Single-mode long-reach links within enterprise and telecom networks

Key specifications

• Fibre type: single-mode, G.657.A1 compatible
• Core diameter: 9 µm
• Length: 2 m
• Connector type: LC to LC
• Cable jacket colour: yellow
• Typical insertion loss: industry-standard low values (dependent on connector/mating)
• Suitable for high-density installations due to compact connector size

How to use

Identify the LC ports on the network devices to be connected and ensure both devices support single-mode SFP transceivers. Gently align each LC connector with the corresponding port and insert until a tactile click confirms proper mating. Avoid excessive bending near the connector boots; route the cable following existing cable management channels or bend-control guides. When disconnecting, depress the LC latch and pull straight out to avoid damaging the ferrule or connector housing.

Usage recommendations

For optimal performance, use the cable within recommended bend radii and avoid tight kinks. Keep connector end-faces clean and free of dust; inspect and, if necessary, clean with appropriate fibre cleaning tools before connection. Store spare cables in protective sleeves to prevent contamination and mechanical damage.
