Fibre optic cable LANBERG FO-SASA-SS31-0250-WH 25 m SC–SC G.657.B3 125 µm White

Fibre optic cable LANBERG FO-SASA-SS31-0250-WH is a 25 m single-mode (SM) simplex cable with SC–SC APC connectors and G.657.B3 fibre. The cable features a 9/125 µm core/cladding configuration, a compact 3.0 mm diameter and LSZH jacket for indoor use. Designed for low-bend-loss applications, this white SC–SC patch lead provides reliable connections for optical equipment links, data centres and telecom installations where tight routing and modest space are required.

Advantages

The G.657.B3 fibre minimizes signal loss at tight bend radii while maintaining low insertion loss (< 0.25 dB) and high return loss (> 60 dB) thanks to APC-polished SC connectors. The LSZH coating reduces hazardous smoke and corrosive gases in case of fire, making the cable suitable for indoor and data centre environments. Its 3.0 mm simplex construction and 25 m length offer a balance of flexibility and reach for structured cabling runs.

Suitable for

• Interconnects between optical equipment and active devices in data centres
• Indoor telecom cabling and rack-to-rack patching
• Tight-routing installations where small bend radius is required
• Optical links in offices, server rooms and central wiring closets

How to use

Install the LANBERG FO-SASA-SS31-0250-WH by gently routing the cable along cable trays or through conduits, avoiding excessive pulling or sharp kinks. Align SC connectors with the device adapter ports and push until they click into place; the APC polish requires precise seating to maintain low return loss. Ensure the minimum bend radius of 5 mm is not violated during installation and secure the cable with appropriate clips or ties that do not compress the jacket. For testing, verify insertion loss and return loss with suitable optical test equipment after termination.

Usage recommendations

For optimal performance, route the cable with smooth curves rather than tight angles, avoid repeated bending at the same point, and use protective tubing or patch panels in high-traffic areas. Use proper ESD-safe handling when connecting to sensitive optical equipment and confirm connector cleanliness before mating to maintain low insertion and return loss.
