## Summary description

The BlueOptics R9F77A-BL is a 1 m InfiniBand/fibre optic cable featuring QSFP28 connectors on both ends. Designed for high-speed data transmission, it ensures reliable connectivity for data centers and networking applications. The male/male configuration allows for easy installation and compatibility with various devices.

## Long description

The BlueOptics R9F77A-BL InfiniBand/fibre optic cable is a 1 m QSFP28 Male-to-Male connection designed for short-range, high-speed links in data center and networking environments. It supports 100G Ethernet and InfiniBand applications, providing a direct attach connection between QSFP28 ports. The cable is intended for use where low latency, low power consumption and reliable electrical signal transfer are required over a one metre distance.
Advantages
This 1 m QSFP28 male/male cable offers a compact, passive direct attach solution for connecting switches, routers and storage systems that accept QSFP28 interfaces. The cable conforms to common MSA electrical and mechanical requirements for QSFP28 direct attach cables and uses 30 AWG twinax construction for consistent signal integrity. Compared with active modules, the passive design keeps power consumption and latency low while providing a cost-effective link for rack-to-rack or in-rack connections.
Suitable for
100G Ethernet connections between compatible QSFP28 ports
InfiniBand links in server and storage environments
Short-range direct attach connections inside racks or between adjacent racks
High-density switch-to-switch or switch-to-server cabling
Key specifications
Connector type: QSFP28 Male to QSFP28 Male
Length: 1 metre
Maximum data rate: up to 100 Gbps
Cable type: passive twinax copper, 30 AWG
Supported protocols: 100GBase-CR4 Ethernet, InfiniBand, FCoE and Fibre Channel (protocol-dependent)
Application: short-distance direct attach for racks and adjacent racks
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port until the latch engages. Ensure both connected devices support passive QSFP28 direct attach copper cables and the selected protocol. After installing, verify link status on both devices and check negotiated speed and protocol compatibility through the host interfaces or management software. Avoid sharp bends and maintain the minimum bend radius specified by the hardware vendor to preserve signal integrity.
Usage recommendations
Use this 1 m QSFP28 passive cable for short, high-bandwidth links where low latency and low power consumption are priorities. Confirm vendor compatibility for passive direct attach cables and test a sample in your environment if exact hardware support is required. Store the cable in a dry, dust-free area and avoid excessive mechanical stress to maximise service life.
