LR-LINK QSFP28-4xSFP28-AOC-3m uses OM3 multimode fiber,which is suitable for merging 100G QSFP28 and 25G SFP28 enabled host adapters, switches and servers.For typical applications, users can install this breakout or splitter cable between an available QSFP28 port on 100Gbps switch and feed up to 4 upstream SFP28 enabled 25Gbps switches. Each cable features a single SFF-8436 compliant QSFP28 connector rated for 103Gb/s on one end and 4 SFF-8431 complicant SFP28 connectors rated for 25.78Gb/s each on the other end.
The QSFP28-4xSFP28-AOC-3m active optical cable can be used as a drop-in replacement for traditional cable (DAC), with lighter weight and smaller diameter. QSFP28-4xSFP28-AOC-3m provides a standard length of 3m,which is suitable for application scenarios such as 100G Ethernet application.
