## Summary description

The BlueOptics SFP3133FU7.5MK is a 7.5 m fibre optic cable designed for high-speed data transmission. It features OM4 fibre type, LC and ST connectors, and a core diameter of 50 µm, ensuring full duplex communication. Ideal for InfiniBand applications, it provides reliable performance and high bandwidth.

## Long description

BlueOptics SFP3133FU7.5MK is a 7.5 meter duplex fiber optic patch cord with LC/UPC to ST/PC connectors, laser-optimized multi-mode OM4 fiber (50/125 µm) and a magenta LSZH jacket. It is designed for 850 nm signal transmission and suitable for connecting patch panels, optical transceivers and other fiber network components in high-bandwidth environments such as InfiniBand links.
Advantages
The cable uses laser-optimized OM4 multi-mode fiber offering low attenuation (2.5 dB/km) and high return loss. Connectors use zirconia ceramic ferrules and branded components to ensure mechanical reliability and up to 1500 mating cycles. Production testing includes interferometer and OTDR measurements, and each unit ships with a protocol of insertion loss and return loss values. The LSZH jacket reduces smoke emission and contains no halogens.
Suitable for
InfiniBand high-speed links
Connections between optical transceivers
Interconnections on patch panels and fiber distribution frames
Short- to mid-reach multimode data center links
Key specifications
Fiber category: OM4 (laser-optimized multi-mode)
Core/cladding diameter: 50/125 µm
Length: 7.5 m
Connectors: duplex LC/UPC to ST/PC
Operating wavelength: 850 nm
Attenuation: approx. 2.5 dB/km
Jacket: LSZH (low smoke, zero halogen)
Durability: up to 1500 mating cycles for connectors
How to use
Route the duplex cable between the devices to be connected, ensuring correct duplex orientation for transmit and receive channels. Insert the LC connectors into LC ports and the ST connectors into ST ports until they click or lock; avoid sharp bends and maintain the minimum bend radius specified by the manufacturer. For best performance, keep connectors clean and inspect or clean endfaces before mating.
Usage recommendations
Store and install the patch cord in dry, dust-free environments; use protective caps when connectors are not in use. For critical links, verify insertion loss and return loss against the supplied measurement protocol after installation.
