CBO QSFP28 100Gbit/s BlueOptics 3m Male-to-Male optical cable

The CBO QSFP28 100Gbit/s BlueOptics 3m Male-to-Male optical cable is a 3-meter direct-attach cable designed for high-density, short-reach 100 Gbit/s links. With male QSFP28 connectors on both ends it supports direct connections between compatible switches, routers and servers in data centre and enterprise network environments. The cable provides a compact, low-latency physical connection that is suitable for top-of-rack, aggregation and computing cluster applications where space and signal integrity are important.

Advantages

This BlueOptics QSFP28 cable offers a reliable, single-segment solution for 100 Gbit/s links without the need for separate transceivers. The fixed-length 3 m design reduces insertion points and potential signal loss compared with patchcord-plus-transceiver options. Male QSFP28 connectors ensure compatibility with equipment that accepts QSFP28 direct-attach cables, and the assembly supports plug-and-play installation for quick deployment. The cable's form factor and materials are optimized for high-density racks and constrained cable paths.

Suitable for

• Short-reach interconnects between switches and routers in data centres
• Direct server-to-switch connections in high-performance computing clusters
• Top-of-rack and aggregation layer links where 100 Gbit/s throughput is required
• Environments that require low latency and compact cabling

Key specifications

• Interface: QSFP28 male to QSFP28 male
• Data rate: 100 Gbit/s
• Length: 3 meters
• Signal type: Optical direct-attach cable for short-reach links
• Connector gender: male on both ends
• Use case: Direct-attach, fixed-length cable for high-density installations

How to use

Ensure both endpoints support QSFP28 direct-attach cables and are powered down or follow hot-plug procedures recommended by the equipment vendor. Align each male QSFP28 connector with the corresponding port and insert until it seats firmly; observe any port latching mechanism if present. After insertion, verify link status via the connected devices' management interfaces. For removal, release the latch and extract the connector straight out to avoid bending or stressing the cable. Do not route the cable through sharp bends and avoid excessive pulling force to maintain optical performance.

Recommendations

Install the cable in rack layouts that avoid tight bends and maintain manufacturer-recommended bend radii. Keep mating surfaces clean and protect connectors from dust when not in use. Use this 3 m QSFP28 cable for short interconnects inside racks or between adjacent racks rather than long-span backbone links.
