HPE Aruba JL487A – 25G SFP28‑to‑SFP28 Direct Attach Cable
Overview :
The HPE JL487A is a purpose‑built 25 Gigabit Ethernet (25G) direct‑attach cable (DAC) using an SFP28 interface at both ends, designed for short‑reach interconnects such as adjacent rack or within‑rack switch links. With a fixed 0.65 m (approximately 2.1 ft) passive twinax copper construction, it supports 25 Gb/s bi‑directional data transfer while maintaining low latency and low power consumption. It is compatible with the SFP28 form‑factor and meets the required MSA and SFF‑8402 electrical specifications. The cable is typically used in DC‑class data‑centre deployments, for example linking 25G SFP28 ports on switches and servers, and is best suited for environments with high port density and short‑distance connectivity requirements. Its passive design removes the need for an external power supply and simplifies deployment between compatible 25G‑capable SFP28 ports.
