Cabo InfiniBand/fibra ótica BlueOptics 100G-Q28-Q28-C-0201 2 m QSFP28 macho/macho

The BlueOptics 100G-Q28-Q28-C-0201 is a 2 m InfiniBand/fibre optic cable with QSFP28 male-to-male connectors designed for 100G data transmission. Engineered for data center and high-performance networking environments, this cable supports full-rate 100 Gigabit links and provides a compact, low-latency connection between compatible QSFP28 ports. The cable's construction focuses on signal integrity and reliable physical mating to maintain consistent throughput in dense rack and switch installations.

Advantages

This 2 m QSFP28 cable offers low insertion loss and high return loss characteristics suitable for short-reach 100G connections. Its fixed-length assembly eliminates the need for transceivers when connecting QSFP28 ports directly, reducing power consumption and component count. The cable's male/male QSFP28 terminations ensure straightforward plug-and-play operation with compatible switches, network adapters, and active devices that accept QSFP28 passive or active cables.

Suitable for

• Direct connections between QSFP28 ports in racks and switches
• Top-of-rack (ToR) and spine-leaf network links in data centers
• High-performance computing clusters using InfiniBand or Ethernet at 100G
• Short-reach uplinks and cross-connects in server rooms

Key specifications

• Cable type: InfiniBand / fibre optic QSFP28 cable
• Data rate: 100 Gbit/s support for full-rate links
• Length: 2 metres
• Connector style: QSFP28 male to QSFP28 male
• Application: Short-reach high-speed interconnects in data centers
• Typical characteristics: low insertion loss and suitable return loss for 100G links

How to use

Identify two compatible QSFP28 ports on the devices you intend to connect (switches, adapters, or NICs) and ensure both ports are configured for the same link speed and protocol. Align the QSFP28 connector keying and insert the cable plug until it seats firmly; confirm the connection status via the device link/activity indicators or management interface. For removal, release any retention mechanism on the connector and withdraw the plug straight out to avoid damage. Avoid bending the cable sharply near the connector ends to maintain signal performance.

Recommendations

Use this cable for short-range 100G interconnects within racks or between adjacent racks. Verify compatibility with your hardware vendor's QSFP28 port policy and check device firmware for supported passive or active cable types. Handle connectors by the housing, keep dust caps on unused ends, and follow standard data center cable management practices to ensure reliable operation.
