InfiniBand/fibre optic cable BlueOptics 845410-B21-BO 7 m SFP28 Male/Male

The BlueOptics 845410-B21-BO is a 7 m InfiniBand/fibre optic active optical cable with SFP28-compatible male connectors on both ends. Designed for high-speed short-range links, this cable supports multi-mode optical transmission and is intended for use in data center and networking equipment that accepts SFP28/SR4-style active optical connections. The pre-assembled AOC construction eliminates the need for separate transceivers and patching, providing a direct optical link with low latency and immunity to electromagnetic interference.

Advantages

This BlueOptics 7 m active optical cable offers a ready-made fibre connection with integrated transmitter and receiver electronics at each end, reducing installation complexity and the need for patchcord cleaning. The multi-mode optical design provides high data throughput suitable for 100GBASE-SR4 applications over short distances while maintaining signal integrity. Built according to MSA-aligned specifications and using high-quality optical and electronic components, the cable aims to deliver stable operation and long service life in professional network environments.

Suitable for

• Short-range 100 Gbps links between switches and routers in data centres
• Interconnects for high-performance storage systems and server clusters
• Low-latency InfiniBand and Ethernet backbone connections within racks or between adjacent racks

Key specifications

• Cable type: Active optical cable (AOC) with multi-mode fibre
• Length: 7 metres
• Connector type: SFP28-style male connectors on both ends
• Supported data rates: up to 100 Gbps for SR4-compatible applications
• Transmission medium: optical laser-based multi-mode transmission
• Digital diagnostics: supports DDM/DOM monitoring when host hardware provides support

How to use

Install the BlueOptics 7 m AOC by inserting the SFP28-style male connectors into compatible SFP28 or QSFP28 ports on networking equipment, ensuring connectors are aligned and fully seated. Verify that the host devices support active optical cables and DDM/DOM if diagnostic monitoring is required. After insertion, check link status and diagnostics through the switch or host management interface. The pre-terminated design requires no additional polishing or splicing.

Usage recommendations

Use the cable for short-range, high-bandwidth optical links inside racks or between adjacent racks. Avoid tight bends and excessive pulling force; follow recommended bend radius for optical cables. Ensure the connected hardware officially supports active optical cables of this form factor to guarantee full functionality and access to digital diagnostic features.
