Fiber optic cable CBO SFP3138BU20MK — 20 m, LSZH jacket, G.657.A1, 2x LC to 2x E-2000 APC, yellow

CBO SFP3138BU20MK is a 20-meter single-mode fiber optic cable with a low-smoke zero-halogen (LSZH) jacket and G.657.A1 bend-insensitive fibers. The cable is supplied in a yellow outer jacket and terminated with two LC connectors on one end and two E-2000 APC connectors on the opposite end. It is designed for indoor optical links, patching and equipment interconnection where reduced bending loss and a flame-retardant, low-toxicity jacket are required.

Advantages

This fiber optic cable provides bend-insensitive performance due to G.657.A1 fibers, maintaining signal integrity in confined routing environments. The LSZH jacket reduces toxic gases and dense smoke in case of fire, making the cable suitable for installation in public buildings and technical rooms where safety standards call for low-halogen materials. Dual pair termination (2x LC to 2x E-2000 APC) supports duplex single-mode connections and simplifies direct interconnection between different device connector types without additional adapters.

Suitable for

• Indoor backbone and horizontal patching in data centres and comms rooms
• Interconnection between network equipment with LC and E-2000 APC ports
• Environments with limited bend radius such as cable trays, ducts and patch panels

Key specifications

• Length: 20 m
• Fiber type: Single-mode, bend-insensitive G.657.A1
• Jacket material: LSZH (low-smoke zero-halogen)
• Color: Yellow outer jacket
• Connectors: 2 x LC (one end) to 2 x E-2000 APC (other end)
• Polish type on E-2000: APC (angled physical contact)

How to use

Inspect connector endfaces for cleanliness before insertion and use appropriate dust caps until installation. Route the cable following the recommended minimum bend radius for G.657.A1 fibres to preserve optical performance; avoid sharp bends and excessive twisting. Connect the 2x LC end to the equipment or patch panel with LC ports and the 2x E-2000 APC end to devices or adapters that accept E-2000 APC connectors. Secure the cable in trays or fastenings to prevent strain on the terminations and maintain consistent bend radii along the run.

Usage recommendations

For best performance, clean connectors with a suitable fiber cleaning tool prior to mating and perform an optical power or loss test after installation. Store and handle the cable in a dry environment and avoid exposure to temperatures or conditions outside the manufacturer's specified ranges.
