BlueOptics SFP6143EU3MKB InfiniBand fibre optic cable 3 m OM3 MTP ST

The BlueOptics SFP6143EU3MKB InfiniBand fibre optic cable is a 3 m multi-mode OM3 MTP to 4×ST breakout cable designed for high-speed data transmission in data centers and networking environments. It features an 8‑core OM3 fiber (50/125 µm) with a single MTP/UPC multi-fiber connector on one end and four ST/PC duplex connectors on the other end. The cable is optimized for 850 nm operation, provides low insertion loss and high return loss, and comes with a flame-retardant LSZH (Low Smoke Zero Halogen) sheath for improved safety in enclosed spaces.

Advantages

This MTP to 4×ST breakout cable enables compact, pre-terminated fiber connections that reduce installation time and eliminate the need for onsite splicing or special tooling. Manufactured with industry-grade fibers and branded connector components, it delivers consistent optical performance supported by interferometer and OTDR end‑of‑line testing and an included measurement protocol for insertion loss and return loss. The LSZH jacket minimizes smoke and halogen release in case of fire and the polished zirconia ferrules support long connector lifetime and reliable mating cycles.

Suitable for

• Data center trunking and rack-to-rack connections
• InfiniBand and high-speed interconnects in storage area networks (SAN)
• Connections to MTP cassettes and patch panels with ST interfaces
• Local area network links and equipment interconnects requiring OM3 multi-mode fiber

• Low insertion loss and high return loss (measurement protocol included)
• Tested with interferometer and OTDR
• Connector ferrule: zirconia ceramic for durable mating cycles

How to use

Install the MTP connector into the corresponding MTP port or cassette designed for multi-fiber interfaces, and route the four ST duplex connectors to the target ST ports on switches, transceivers or patch panels. Ensure connectors and ports are clean before mating to maintain low insertion loss. Secure the cable along rack pathways or cable management guides to prevent strain on connectors and avoid tight bends below the fiber's minimum bend radius. No splicing or additional assembly is required; the pre-terminated breakout arrangement allows immediate use after connection.

Usage recommendations

Before installation, verify the fiber type and connector compatibility with your equipment and check the included measurement protocol. Use appropriate dust caps until final connection, perform connector cleaning with suitable fiber cleaning tools, and avoid bending the cable sharply. For installations in public or confined spaces prefer the LSZH jacket for reduced smoke and halogen emissions.
