The Etern 100G QSFP28 PSM4 supports link lengths of up to 2km (PSM IR4) FLS100P02S or 10km (PSM LR4) FLS100P10S on G.652 Single-Mode Fiber (SMF). It enables high-bandwidth 100G optical links over 12-fiber parallel fiber terminated with MPO/MTP multifiber female connectors. It can also be used in a 4x25G mode for interoperability with 25GBASE-LR interfaces up to 2km or 10km.
The 4x25G connectivity is achieved using an external 12-fiber parallel to 2-fiber duplex breakout cable, which connects the 4x25G LR module to four 25GBASE-LR optical interfaces.
