DIGITUS DN-81630 — 100G SR4 QSFP28 on MPO
100 GbpsQSFP28 SR4MPO/MTPOM4 100 m
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.
Compatibility — check before buying:
This is an SR4 module, not CWDM4: it needs an MPO/MTP multimode trunk and will not take a duplex LC patch cord or run over single-mode fibre. Reach is 70 m on OM3, 100 m on OM4. DIGITUS lists many compatible brands but states no vendor-specific coding, so switches that lock out third-party optics may refuse it. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your device model and the cable run and we check it before you order.
Best For
✓ 100G links inside one data room
✓ Switch-to-switch uplinks on MPO trunks
✓ QSFP28 ports that accept MSA optics
✓ OM3 / OM4 structured cabling
✓ Cost-conscious 100G builds
✓ Spare 100G SR4 optics
Key Features
100G on short multimode runs
Four 25G lanes at 850 nm carry 100 Gbps over an MPO/MTP trunk, up to 100 m on OM4.
Multimode fibre, short reach
Built for the short runs inside a building or data room over OM-grade multimode fibre. Reach depends on the fibre grade — check what is actually in your walls before you plan a link.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.
Plan both ends together
A link only comes up when both ends use the same standard, speed and media. Order the far-end module, the cable and any spares in one go and the link works on day one.

Frequently Asked Questions
Singular Expert Insight
The DN-81630 is a sensible choice for 100G links inside one room where the switch accepts third-party optics. Before ordering, confirm two things with us: that your switch does not lock out uncoded modules, and that the MPO trunk is OM3 or OM4 and within 70 or 100 m. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status and we help you find out whether it is the module, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You need 100G over MPO multimode within 100 m on a switch that accepts MSA optics.
Skip it if
Your fibre is duplex LC or single-mode, the run is over 100 m, or the switch only accepts its own brand of optics.
