BlueOptics MCP1600-C0005-BL InfiniBand-glasvezelkabel 5 m QSFP28 stekker/stekker

The BlueOptics MCP1600-C0005-BL InfiniBand Fibre Optic Cable 5 m QSFP28 Male/Male is a 5‑metre high‑speed interconnect designed for short‑reach links in data centres and high‑performance computing racks. It features QSFP28 connectors on both ends and supports 100 Gbps class InfiniBand and Ethernet protocols over a passive direct‑attach connection. The cable is intended for reliable point‑to‑point connections between compatible QSFP28 ports, enabling low‑latency, high‑bandwidth links for switches, servers and storage hardware.

Advantages

This QSFP28 male‑to‑male cable provides a cost‑effective, low‑power alternative to active optical modules for short distances. Its direct‑attach design delivers minimal latency and stable electrical signal transmission suitable for 100GBase‑CR4 and InfiniBand environments. Manufactured to common MSA guidelines and built with high‑quality components, the cable offers dependable interoperability with major hardware platforms that support the corresponding Mellanox/MCP1600‑C0005 compatible specification.

Suitable for

• Rack‑to‑rack or within‑rack 100 Gbps connections between QSFP28 ports
• High‑performance computing clusters and InfiniBand fabrics
• Switches, routers and storage arrays that accept passive DAC QSFP28 links
• Short‑reach data centre interconnects up to 5 metres

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 5 m
• Supported data rates: up to 100 Gbps
• Supported protocols: InfiniBand and 100GBase‑CR4 Ethernet (passive DAC)
• Cable type: passive direct attach twinax (electrical signaling for short distances)
• Wire gauge: 26 AWG (typical for twinax DAC implementations)
• Low power consumption and low latency suitable for dense rack deployments

How to use

Install the cable by firmly inserting each QSFP28 connector into the corresponding QSFP28 port until the latch engages. Ensure devices are powered down or support hot‑plugging per vendor guidelines before insertion or removal. The cable functions as a passive link; confirm that the connected hardware supports passive 100G DAC connections and the chosen protocol (InfiniBand or 100GBase‑CR4). After connection, verify link status and negotiated speed via the host or switch management interface.

Recommendations

Use this 5 m passive QSFP28 direct‑attach cable for short, high‑bandwidth links inside racks or between adjacent racks. Avoid bending the cable beyond manufacturer‑recommended bend radius and keep connectors free of dust. For guaranteed compatibility, check that the device firmware and hardware explicitly support passive DAC QSFP28 modules and that port settings match the intended protocol.
