3AL82217AA Nokia (Alcatel-Lucent) Compatible 100GBASE-SR4 QSFP28

EdgeOptic's 3AL82217AA compatible is a Nokia-coded 100GBASE-SR4 version of the EdgeOptic 100G-QSFP28-100 multi-vendor 100GBASE-SR4 transceiver, one universal short-reach module coded across multiple vendor platforms. It carries 100G Ethernet over four parallel 850 nm VCSEL lanes at 25G each across multimode fiber, terminated on an MTP/MPO-12 (UPC) connector that uses 8 active fibers, 4 transmit and 4 receive. The transceiver port is female (unpinned); the patch cable is the pinned male side, so a transceiver-to-transceiver run needs a male-to-male Type B cable. Reach is 70 m over OM3 and 100 m over OM4, per IEEE 802.3bm Clause 95.

Optical specifications include a 1.9 dB average link budget, receiver sensitivity of −10.3 dBm per lane, NRZ modulation, and no FEC required at this reach. The transmitter uses 850 nm VCSEL sources; the receiver is a PIN photodiode. OM4 supports the full 100 m while OM3 is rated to 70 m, with achievable distance depending on patch panels, splices, and connector cleanliness in the installed link. DDM/DOM is supported per SFF-8636, so the host can read per-lane transmit power, receive power, and bias along with module-level temperature and voltage. The module runs across the 0°C to 70°C commercial range at 3.5 W maximum and is compliant with the QSFP28 MSA and SFF-8665.

The Nokia 3AL82217AA is a multi-rate OEM part that, beyond 100GBASE-SR4 Ethernet, is documented across the market as also supporting OTU4 and 128G Fibre Channel. This EdgeOptic compatible is coded for the 100GBASE-SR4 Ethernet application only; it does not cover OTU4 or 128G Fibre Channel. If your deployment requires the OTU4 or Fibre Channel modes of the original Nokia module, our sales team can advise on the right part for that requirement.

EdgeOptic codes this compatible with Nokia-recognized EEPROM for use on Nokia QSFP28 platforms, including Nokia service router and aggregation platforms with 100G short-reach ports. Confirm the specific platform and port card against Nokia's transceiver compatibility guide for your deployment. Typical roles include data center core interconnects, ISP aggregation, and mobile operator core networks.
