Fiber Patch Cable CBO SFP5141BU3MKB — 3 m, Singlemode G.657.A1

CBO SFP5141BU3MKB is a 3 m singlemode fiber patch cable designed for high-speed optical connections. Compliant with ITU-T G.657.A1, this BlueOptics cable features a tight-bend tolerant singlemode fiber that reduces signal loss in confined routing environments. The cable is intended for indoor use and provides consistent transmission performance for access networks, fiber-to-the-home (FTTH) installations and short backbone links.

Advantages

The G.657.A1 specification ensures low bending loss and stable optical performance when routed through tight spaces, conduits or bend-prone installations. At 3 meters length the cable offers flexibility for patching between equipment in telecom racks, optical distribution frames and residential ONT setups. The BlueOptics build quality supports reliable mating with SFP modules and standard fiber connectors while maintaining consistent insertion loss and return loss characteristics.

Suitable for

• Fiber-to-the-home (FTTH) connections
• Indoor patching in telecom racks and data cabinets
• Short backbone and horizontal links in buildings
• Connections to SFP transceivers and optical network terminals (ONT)

Key specifications

• Fiber type: singlemode, ITU-T G.657.A1
• Length: 3 m
• Design: bend-insensitive structure for reduced macrobend loss
• Typical use: indoor patch cable for access and distribution
• Connector compatibility: designed for standard singlemode SFP and optical ports

How to use

Route the cable between devices avoiding unnecessary strain and sharp kinks; maintain recommended bend radii as specified by G.657.A1 to preserve optical performance. Connect each end to the appropriate singlemode ports on your SFP transceiver, ONT or optical patch panel. For repeatable connections, insert and secure connectors until they click or seat fully; inspect connector endfaces for contamination and clean with appropriate fiber cleaning tools when required.

Usage recommendations

Use this 3 m G.657.A1 patch cable for indoor fiber runs where space is limited or bends are unavoidable. Store and handle the cable in a way that prevents tight kinks, keep connector endfaces clean, and verify link performance with an optical power meter or compatible network diagnostics after installation.
