## Summary description

The BlueOptics 7Z57A03562-BL is a 3 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 7Z57A03562-BL is a 3 m InfiniBand/fibre optic twinax cable with QSFP28 connectors on both ends, designed for high-speed short-reach interconnects in racks and adjacent racks. The cable supports 100G data transfer rates and is intended for use where reliable, low-latency electrical or optical links are required between switches, routers, storage systems and other network hardware that accept QSFP28 to QSFP28 connections.
Advantages
This 3 m QSFP28 male-to-male cable provides a direct-attach solution for short distance links with low power consumption, low latency and a simple passive design that reduces failure points. Manufactured to multi-source agreement (MSA) guidelines and assembled from quality components, it offers compatibility across major hardware platforms and consistent signal integrity for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 100G. The passive twinax design keeps operational complexity low and helps maintain predictable performance in dense data center environments.
Suitable for
100G direct connections between rack-mounted switches
Interconnects between routers, storage arrays and switches in adjacent racks
High-throughput fabrics using InfiniBand or 100G Ethernet protocols
Short-reach links in data center top-of-rack and spine deployments
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 3 meters
Supported data rates: up to 100 Gbps
Cable type: passive twinax (suitable for short-distance electrical transmission)
Wire gauge: 26 AWG conductor
Standards compliance: QSFP DAC MSA electrical/mechanical specification; designed for use with Ethernet, FCoE, Fibre Channel and InfiniBand protocols
How to use
Install the cable by inserting each QSFP28 plug into the corresponding QSFP28 port on your networking devices until the latch secures. Ensure both connected devices support passive QSFP28 direct-attach twinax cables and the intended protocol (for example 100G Ethernet or InfiniBand). Route the 3 m cable within the rack or between adjacent racks to avoid sharp bends and mechanical strain. No additional power or transceivers are required for passive operation; device interfaces handle signalling and protocol negotiation.
Usage recommendations
Before deployment, verify device compatibility with QSFP28 passive DACs and confirm firmware or driver support for 100G links. Maintain bend radius according to manufacturer guidance, avoid crushing or kinking the cable, and perform link verification tests after installation to confirm expected throughput and latency.
