## Summary description

The BlueOptics JL307A-BL is a 3-meter InfiniBand fibre optic cable featuring QSFP28 connectors on both ends.

The male-to-male configuration allows for easy integration with compatible devices, making it an ideal choice for enhancing network performance.

## Long description

The BlueOptics JL307A-BL InfiniBand Fibre Optic Cable 3m QSFP28 Male Male is a 3‑meter high‑speed interconnect designed for short‑reach connections in data centres and high‑performance networking environments. Featuring QSFP28 connectors on both ends, it supports InfiniBand and 100G applications where reliable, low‑latency optical links are required. The cable is intended for integration with devices that accept QSFP28 to QSFP28 connections and provides a fixed-length, factory‑tested optical solution for cluster, switch‑to‑switch and switch‑to‑server links.
Advantages
The BlueOptics JL307A-BL offers a compact, single‑cable solution for 100G InfiniBand links with QSFP28 interfaces. As a pre‑terminated fibre optic assembly it reduces installation time and risk of connector contamination compared with field‑terminated fibres. The cable provides consistent signal integrity over the specified 3 m reach and is designed to meet industry mechanical and optical expectations for rack and adjacent‑rack connections.
Suitable for
Short‑reach data centre connections between switches and servers
High‑performance computing clusters using InfiniBand or 100G interfaces
Rack and adjacent‑rack interconnect cabling requiring QSFP28 to QSFP28 links
Low‑latency storage and network fabrics where optical links are preferred
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 3 metres
Media: fibre optic (single assembly, factory‑terminated)
Supported protocols: InfiniBand and 100G Ethernet applications (per device support)
Typical use: short‑reach, rack and adjacent‑rack links with low latency requirements
How to use
Install by aligning each QSFP28 connector with the corresponding port on the network device and insert until the latch engages. Verify port configuration and transceiver/port compatibility before enabling traffic. Use a single, fixed route between devices to avoid excessive bending; follow equipment manufacturer bend radius limits. After installation, perform link‑level tests or diagnostic commands on your switches or hosts to confirm the link is up and operating at the expected rate.
Usage recommendations
Handle the cable by the connector housing where possible and avoid pulling on the fibre assembly. Observe minimum bend radius and secure the cable in the rack to prevent strain. Confirm device compatibility with QSFP28 optical assemblies and keep connector dust caps in place until final insertion to maintain optical performance.
