## Summary description

The BlueOptics SFP3333EU3MK is a 3 m InfiniBand fibre optic cable featuring 2x ST connectors. It utilizes OM3 fibre optic type with a core diameter of 50 µm, ensuring full duplex communication for efficient data transfer. Ideal for high-speed networking applications.

## Long description

The BlueOptics SFP3333EU3MK InfiniBand fibre optic cable is a 3 m duplex link with two ST connectors, designed for short- to medium-range high-speed networking. Constructed with OM3 multimode fibre (50 µm core), this cable supports full duplex data transmission and is intended for InfiniBand environments where low latency and reliable signal integrity are required. The cable's straightforward ST terminations make it compatible with equipment that accepts bayonet-style multimode connectors.
Advantages
This fibre optic cable offers multimode OM3 performance suitable for high-bandwidth links over a few meters, providing consistent signal quality and minimal attenuation across the run. The duplex configuration enables simultaneous bidirectional communication, and ST connectors provide a secure mechanical connection with wide equipment compatibility. The 3 m length balances flexibility for rack-to-rack or rack-to-switch connections while keeping excess cable management minimal.
Suitable for
 InfiniBand interconnects in server rooms and data centers
 Short to medium distance multimode fibre links (up to a few tens of meters depending on equipment)
 Connections between switches, transceivers and network interface cards that accept ST connectors
 Applications requiring full duplex high-throughput links with low latency
Key specifications
 Length: 3 m
 Fibre type: OM3 multimode
 Core diameter: 50 µm
 Connector type: 2× ST (duplex)
 Transmission mode: full duplex
 Intended application: InfiniBand high-speed networking
How to use
Inspect connector end-faces and ensure cleanliness before insertion. Align each ST connector with the corresponding ST receptacle on your transceiver or port, push in and twist the bayonet coupling to lock. Use one fibre per direction for duplex operation. Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius recommended for OM3 multimode fibre. If needed, secure the cable with appropriate cable management to prevent strain on connectors and maintain optimal performance.
Usage recommendations
Keep connector end-faces free from dust and contaminants by using dust caps when ports are unused and perform periodic cleaning with approved fibre cleaning tools. For longer runs or different distance requirements, verify link budget and wavelength compatibility with your InfiniBand equipment and consider alternative fibre types or connector formats if necessary.
