DIGITUS DN-81630 QSFP28 Transceiver 100GBASE-SR4 850 nm MPO/MTP Multimode up to 100 m on OM4
DIGITUS DN-81630 — 100G SR4 QSFP28 on MPO
The DIGITUS DN-81630 is a 100 Gbit QSFP28 transceiver of the SR4 type: four parallel 25G lanes at 850 nm over an MPO/MTP multimode trunk, reaching up to 70 m on OM3 and 100 m on OM4. It is a hot-pluggable MSA module for short 100G links between switches and servers in the same data room, drawing under 3.5 W. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry OM3 or OM4 fibre, and the module plus a short patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.
