Fiber optic cable BlueOptics SFP2121BU20MM, 20 m, LC connectors, G.657.A1, yellow

Single-mode fiber optic patch cable BlueOptics SFP2121BU20MM, 20 m length, terminated with LC connectors and manufactured from G.657.A1 bend-insensitive fiber. The cable is intended for indoor use in structured cabling, connecting optical transceivers, patch panels and distribution frames. The yellow jacket provides visual identification for single-mode links while maintaining low insertion loss and consistent signal quality across local area network and telecommunications environments.

Advantages

The G.657.A1 bend-insensitive fiber minimises signal attenuation in tight routing and small bend radii, reducing the risk of performance degradation in dense installations. LC duplex connectors offer a compact footprint for high-density patching and stable optical contact. The 20 m length covers typical runs between racks or equipment areas without intermediate splices, and the yellow outer jacket aids quick identification of single-mode cabling in mixed-cable environments.

Suitable for

• Indoor optical patching between switches, routers and transceivers
• Connections to patch panels and distribution frames in data centres and comms rooms
• LAN and telecom links requiring bend-insensitive single-mode fiber
• Equipment interconnects where a 20 m pre-terminated cable simplifies installation

Key specifications

• Fiber type: single-mode, bend-insensitive (G.657.A1)
• Length: 20 m
• Connector type: LC duplex on both ends
• Jacket colour: yellow
• Application: indoor patching, data centre and telecom cabling

How to use

Route the cable along designated cable trays or pathways, avoiding sharp edges and excessive tension. Terminate each LC connector into the corresponding LC port of the transceiver, patch panel or equipment, ensuring correct polarity for duplex links. Secure the cable with appropriate management accessories to prevent movement and maintain the specified minimum bend radius. After installation, verify optical continuity and measured insertion loss using appropriate test equipment.

Usage recommendations

For reliable long-term performance, maintain the recommended minimum bend radius for G.657.A1 fiber, avoid crushing and protect connector endfaces from dust by using dust caps until final connection. Use this pre-terminated 20 m LC patch cable for indoor fixed routing where a ready-made single-mode link reduces installation time and potential splice points.
