InfiniBand/optický kábel BlueOptics CAB-Q-Q-100G-5M-BL 5m QSFP28 samec/samec

The BlueOptics CAB-Q-Q-100G-5M-BL is a 5-meter high-speed connectivity cable with QSFP28 connectors on both ends, designed for InfiniBand and short-reach fibre optic or direct-attach Twinax applications. It supports 100G data rates over a 5 m link and is intended for installation inside racks or between adjacent racks in data centers and high-performance computing environments. The cable is compatible with equipment that accepts QSFP28 to QSFP28 connections and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand protocols when used within its supported distance.

Advantages

This cable offers a reliable, low-latency link for short-distance, high-bandwidth connections and is built to industry MSA-compatible connector standards. As a direct-attach solution it provides low power consumption compared with active optical modules, simplified installation and low failure rates due to the passive design. The 5 m length balances reach and signal integrity for rack-to-rack or in-rack connections at 100G.

Suitable for

• Connecting QSFP28 ports between switches and routers inside racks
• High-performance computing clusters and InfiniBand fabric links
• Storage arrays and SAN interconnects using 100G protocols
• Short-reach data center links (rack-to-rack or within a rack)

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable length: 5 meters
• Maximum supported data rate: 100 Gbit/s
• Transmission media: passive direct-attach twinax / short-reach fibre optic use (protocol dependent)
• Conforms to MSA-compatible QSFP28 mechanical and electrical form factors

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your devices until the latch engages. Verify both ends are fully seated and check link status on the connected equipment. Use this cable for short-distance 100G links; it does not require external power or transceivers when used as a passive direct-attach twinax connection and relies on the host hardware to support passive cables at 100G. For optical operation, ensure connected ports and devices support the required optical modules and transceiver settings.

Recommendations

Avoid sharp bends and excessive strain on the cable; maintain the manufacturer’s minimum bend radius and secure the cable to prevent movement in high-traffic areas. Confirm device firmware and hardware compatibility with QSFP28 passive direct-attach cables for full functionality at 100G before deployment.
