CBO QSFP28 7Z57A03561 1 m optical cable, QSFP28 to QSFP28, 1 meter

The CBO QSFP28 7Z57A03561 1 m optical cable is a 1-metre multimode interconnect cable with QSFP28 connectors at both ends, designed for short-reach high-speed links in data center and telecom environments. It provides a direct optical connection between QSFP28 ports on switches, routers or optical transceivers, enabling 100G and compatible link speeds where QSFP28 optics are used. The cable’s compact form and flexible jacket simplify cable routing in dense rack installations while helping to maintain signal integrity over a 1 m distance.

Advantages

This optical cable offers low insertion loss and stable optical performance for short-reach links, reducing the need for external transceivers or complex patching. Its QSFP28-to-QSFP28 terminations ensure compatibility with equipment that accepts QSFP28 form-factor cables, and the 1 m length minimizes excess slack in rack-mounted setups. The flexible jacket and compact connector design facilitate neat cable management in high-density environments.

Suitable for

• Connecting QSFP28 ports between switches or routers within the same rack
• Direct optical links between transceivers in server or storage enclosures
• Short-reach interconnects in data center top-of-rack or spine deployments
• Upgrading or replacing existing multimode short-reach optical patching

Key specifications

• Connector type: QSFP28 to QSFP28 optical connectors
• Length: 1 metre
• Transmission: multimode short-reach optical link suitable for 100G class QSFP28 interfaces
• Jacket: flexible, compact design for high-density routing
• Typical use: direct attach optical interconnect for short distances within racks

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port until it seats securely, following the equipment manufacturer’s instructions for handling QSFP28 modules and ports. Avoid bending the cable sharply near the connector ends; maintain the manufacturer’s recommended minimum bend radius to preserve optical performance. For removal, depress any retention mechanism and withdraw the connector straight out to prevent damage to the port or plug.

Recommendations

For reliable links, verify compatibility with the host device’s QSFP28 port and ensure ports are rated for multimode optical interconnects. Route the cable to avoid tight bends and physical stress, and keep connector end faces clean using appropriate fiber cleaning tools when performing installations or reconfigurations.
