Fiber cable CBO SFP2121BU15MK 15 m, LC connector, G.657.A1 single-mode

Single-mode fiber patch cable BlueOptics SFP2121BU15MK, 15 m length with LC connectors, designed for optical interconnects in data networks. The cable uses G.657.A1 bend-insensitive single-mode fiber suitable for indoor installations and short outdoor runs where tight routing and low loss are required. It is intended for connection of SFP transceivers, switches and other optical equipment, offering consistent signal transmission and flexible placement in constrained spaces.

Advantages

The BlueOptics fiber cable provides bend-insensitive single-mode performance according to ITU-T G.657.A1, reducing signal loss when routed around tight bends. LC connectors ensure compact, high-density connections commonly used with SFP modules and networking equipment. A 15 m length allows connections between equipment in adjacent rooms or within larger rack environments without additional splices or adapters. The construction supports stable, low-loss optical transmission suitable for short-range network links.

Suitable for

• Connecting SFP transceivers to switches and fiber ports
• Inter-rack or room-to-room fiber links up to 15 m
• Installations requiring tight routing or bent pathways
• Indoor cabling and short outdoor runs where G.657.A1 fiber is preferred

Key specifications

• Fiber type: single-mode, bend-insensitive (ITU-T G.657.A1)
• Connector type: LC to LC
• Length: 15 m
• Application: short-range optical patching for networking equipment

How to use

Route the cable avoiding sharp edges and excessive tension. Insert LC connectors into the corresponding LC ports on SFP transceivers, switches or other optical devices until they click into place. Ensure connector endfaces are clean before mating to minimize insertion loss and maintain signal quality. When disconnecting, press the LC latch and withdraw the connector in a straight motion. Coil any excess length in gentle loops and secure to avoid kinks.

Usage recommendations

Inspect and clean connector endfaces with appropriate fiber cleaning tools before installation. Maintain bend radii above the minimum recommended for G.657.A1 fiber and avoid repeated tight bends. Use dust caps when ports are not in use to protect ferrules and ensure reliable optical performance.
