Fibre optic cable Hosa OPM-305, InfiniBand/fibre, 1.5 m, silver

Hosa Technology OPM-305 is a 1.5 m fibre optic cable designed for InfiniBand and other fibre connections, featuring a silver-coloured jacket and polished optical terminations. The cable uses large-diameter Plastic Optical Fiber (POF) that supports digital audio formats including ADAT and S/PDIF (Dolby Digital, DTS). Its construction aims to provide consistent short-range optical links between networking devices, switches, storage systems or digital audio components with Toslink-compatible jacks.

Advantages

The OPM-305 combines a flexible 1.5 m length with a robust silver jacket and polished terminations to minimise signal loss and maintain stable high-speed data transfer over short distances. Large-diameter POF increases coupling efficiency with Toslink-style ports, improving signal clarity for ADAT and S/PDIF signals while the cable’s reinforced construction enhances durability in rack and studio environments.

Suitable for

• Interconnecting InfiniBand or fibre-enabled networking devices at short range
• Connecting digital audio components with Toslink jacks for ADAT and S/PDIF formats
• Data center interconnects and short optical links between switches or storage systems
• Studio and live audio equipment where optical digital signal integrity is required

Key specifications

• Length: 1.5 m
• Cable type: Plastic Optical Fiber (POF), large-diameter
• Jacket colour: Silver
• Terminations: Polished optical terminations for reduced insertion loss
• Supported formats: ADAT, S/PDIF (including Dolby Digital and DTS)
• Use case range: Short-range optical links and local interconnects

How to use

Align each polished optical connector with the Toslink-style ports on your devices and insert gently until seated; avoid forcing the connector. Ensure connectors and ports are free of dust or debris before connection to reduce insertion loss. Route the cable without tight bends—maintain gentle curves to preserve the large-diameter POF core. For removal, pull straight out from the connector body without twisting. When used in networking or storage environments, confirm device settings for optical input/output to match the chosen digital format.

Usage recommendations

For optimal performance, keep optical connector faces clean using a lint-free wipe or canned air and avoid sharp bends or kinks in the cable. Use the 1.5 m length for short-range links; if longer runs are required, select an appropriate longer cable type. When connecting audio equipment, verify sample rate and channel format compatibility between devices before use.
