Fibre optic cable BlueOptics SRCABLE7M-BO 7.5 m LC Beige OM3

The BlueOptics SRCABLE7M-BO is a 7.5 m LC-to-LC OM3 multimode fibre optic patch cable designed for full-duplex, high-speed data transmission in structured networks. It uses laser-optimized OM3 multimode fiber and LC/UPC connectors on both ends to support short-range, high-bandwidth links between patch panels, transceivers and active equipment. The cable features a beige LSZH (low-smoke, zero-halogen) jacket for reduced smoke and no halogen release in case of fire and is intended for industry-standard optical patching environments.

Advantages

This BlueOptics OM3 LC–LC patch cable provides low attenuation and high return loss for reliable signal integrity in multimode links. Connectors employ zirconia ceramic ferrules and industrial-grade components to deliver consistent mating performance and a long service life. Each cable is factory-tested with interferometry and OTDR to document input loss and return loss, and the product is manufactured to recognized industry standards to ensure compatibility with common optical hardware.

Suitable for

• Interconnection of optical transceivers in data centres and server rooms
• Patching between fibre patch panels and network switches
• Short-range, high-bandwidth multimode links (OM3) such as 10/25/40/100 Gbps within racks or between adjacent racks
• Environments where LSZH sheathing is required for safety and low smoke emission

How to use

Route the cable carefully to avoid tight bends and mechanical stress; maintain the recommended minimum bend radius specified for multimode OM3 fiber to preserve optical performance. Clean LC connector endfaces before insertion using appropriate fibre cleaning tools or wipes to avoid contamination-related losses. Insert each LC connector into the matching LC port or adapter until it clicks, ensuring correct duplex orientation for transmit/receive pairing. When removing the cable, depress the LC latch and pull straight to avoid damaging the connector or adapter.

Recommendations

Store the cable coiled loosely and secured with a soft tie; avoid kinking and exposure to temperatures or mechanical stresses outside the manufacturer's specified range. Use this OM3 LC–LC cable for short to medium multimode runs where high bandwidth is needed and choose LSZH-sheathed versions where low smoke and zero halogen emissions are required by the installation environment. For optimal long-term performance, follow regular inspection and cleaning intervals for connectors and retain the supplied test protocol for troubleshooting and verification.
