Ethernet breakout cable CBO JNP-100G-4X25G-5M Cat8.1 QSFP28 to 4×SFP28, 5 m, black

CBO JNP-100G-4X25G-5M Cat8.1 QSFP28 to 4×SFP28 breakout cable is a 5-meter, fixed-length electrical cable designed to convert a single 100G QSFP28 port into four independent 25G SFP28 ports. With a Cat8.1-rated construction and a durable black jacket, the cable delivers short-reach, high-bandwidth connectivity for data center switches, servers, and aggregation equipment where reliable 100G-to-4×25G splitting is required.

Advantages

The cable provides straightforward native electrical breakout without additional modules, supporting multi-lane 100G to 25G conversion in a compact form factor. Its Cat8.1 specification ensures controlled impedance and reduced crosstalk for high-frequency signals over the 5 m length. The fixed-length design simplifies rack and patch-panel installations by eliminating the need for adapters or transceivers for short-distance links.

How to use

Plug the QSFP28 end into the 100G QSFP28 port on the switch, router, or adapter card. Insert each SFP28 connector into the corresponding 25G SFP28 ports on target devices such as servers, NICs, or line cards. Ensure equipment ports are powered down or follow hot-plug guidance from the device vendor if applicable. Verify link status and lane mapping according to the host hardware documentation to confirm proper 100G-to-4×25G operation.

Recommendations

Use the cable for short-distance connections within a rack or between adjacent racks to maintain signal integrity. Avoid tight bends and excessive pulling during installation; maintain manufacturer-recommended bend radius. Confirm compatibility with equipment vendor interoperability lists where precise lane mapping or firmware support is required.
