Fibre optic cable BlueOptics QK731A-BO MPO OM4 50 m Violet

The BlueOptics QK731A-BO MPO OM4 50 m Violet is a 50-meter multimode fibre optic patch cable with MPO/UPC connectors on both ends. Designed for high-density and high-speed network environments, this OM4 cable uses laser-optimized multimode fiber to support short-reach data transmission in data centers, switches and optical transceiver connections. The cable is supplied in violet sheathing for easy identification and organized cabling, and its LSZH flame-retardant jacket reduces smoke and avoids halogen emissions in the event of fire.

Advantages

This MPO-MPO OM4 cable provides low attenuation and high return-loss performance for reliable signal integrity over multi-fiber links. Manufactured with branded fiber and precision connectors, the cable offers consistent component quality and a high mating cycle life. Full production testing with interferometer and OTDR ensures measured input loss and return loss values are documented, meeting common telecommunication requirements for patch cabling.

Suitable for

• Interconnects between patch panels in data centers
• Parallel optics links for high-speed transceivers (MPO systems)
• Structured cabling in server rooms and telecom racks
• Short-reach multimode links requiring OM4 performance

Key specifications

• Fiber type: Multimode OM4, laser-optimized
• Connector type: MPO / UPC on both ends (MPO-MPO)
• Length: 50 meters
• Sheath: LSZH (Low Smoke Zero Halogen), violet color for identification
• Testing: Interferometer and OTDR tested with supplied measurement protocol
• Performance: Low attenuation per kilometer and high return loss suitable for high-density systems
• Durability: Zirconia ceramic ferrules and rated mating cycles for extended service life

How to use

Route the cable along rack guides or cable management trays to avoid sharp bends and mechanical stress; maintain the minimum bend radius recommended for multimode OM4 fiber. Plug the MPO connectors into matching MPO ports on patch panels or transceivers, ensuring correct alignment of the keying to avoid mis-mating. Use the supplied test protocol to verify link loss after installation or perform an OTDR check when integrating into an existing plant. For long-term reliability, secure the cable to strain-relief points and avoid excessive pulling forces during installation.

Recommendations

Store and transport the cable on reels or coiled loops without tight bends. When cleaning connectors, use appropriate fiber cleaning tools and avoid touching ferrule end faces. For best optical performance in high-density MPO systems, match fiber types and maintain consistent polarity and connector type across the link.
