## Long description

The BlueOptics CAB-Q-Q-100G-2M-BL is a 2-meter InfiniBand/fibre optic cable with QSFP28 male-to-male connectors designed for high-speed short-range links. It supports 100G class connectivity and is intended for direct attach use in rack and adjacent-rack environments where reliable, low-latency connections are required between switches, storage systems and servers. The cable is suitable for applications that use QSFP28 interfaces and conforms to common MSA physical connector standards.
Advantages
This QSFP28 2m cable provides a compact direct-attach connection with a male-to-male QSFP28 interface, offering a straightforward plug-and-play solution for 100G links over short distances. Its design focuses on low latency and efficient electrical signal transmission for use in data center topologies. The cable is built to meet industry mechanical and interface conventions and is compatible with hardware platforms that support QSFP28 100G direct attach connections.
Suitable for
Short-range 100G links between switches and routers in racks
Server-to-switch and storage-to-switch connections within rack or adjacent racks
InfiniBand and other 100G-capable network fabrics that use QSFP28 interfaces
High-performance computing and data center aggregation layers requiring direct attach cabling
Key specifications
Connector type: QSFP28 male to QSFP28 male
Nominal length: 2 meters
Supported bandwidth: up to 100 Gbps
Cable type: direct attach (electrical/twinax style for short distances)
Application protocols: Ethernet, InfiniBand and other 100G-capable protocols (subject to device support)
How to use
Identify QSFP28 ports on the two devices to be connected, ensure both devices support passive direct-attach QSFP28 cabling for the intended protocol and power state, and insert each QSFP28 connector firmly into the corresponding port until the latch engages. Verify link status in the host devices and consult device documentation for any platform-specific configuration required for 100G operation. For removal, disengage the connector latch before pulling the cable to avoid port damage.
Usage recommendations
Use this 2m QSFP28 direct-attach cable for short, rack-based 100G connections where passive twinax-style cabling is supported. Confirm compatibility with the specific switch, router or server model and verify that the platform permits passive QSFP28 direct-attach cables for the desired protocol to ensure proper link negotiation and performance.
