Break out a 100G QSFP28 connection into four 25G SFP28 links with an integrated active optical cable assembly. This topology connects one QSFP28 interface to four separate SFP28 interfaces without selecting individual transceivers and patch cords. The 3 m reach suits adjacent equipment, including switch-to-server and switch-to-storage connections within the same rack or across nearby racks. Active optical construction places optical and electrical conversion in the cable ends rather than requiring detachable optics at each connection. Q284S-AO03M-NO-AX carries Nokia-compatible coding for equipment that requires this compatibility profile. Its QSFP28-to-four-SFP28 breakout arrangement is intended for 100G fan-out, not for a one-to-one 100G link. Confirm that the host has a QSFP28 port and that the four downstream interfaces accept SFP28 connections. Choose this cable where a consolidated 100G host connection must serve four 25G endpoints. The four SFP28 branches let one high-speed upstream port connect to separate devices, while the QSFP28 end keeps the host-side connection consolidated. Evaluate the 3 m length against actual rack routing, including vertical managers, cable trays, and the distance between endpoint ports.
