Nokia 3HE10552AA compatible QSFP28 100G CWDM4 2km transceiver

EdgeOptic's 3HE10552AA compatible is a Nokia-coded version of the EdgeOptic 100G-QSFP28-2.1 multi-vendor 100G CWDM4 QSFP28 transceiver. It carries the EEPROM coding Nokia (formerly Alcatel-Lucent) platforms expect, so the module reports as a recognized 100G CWDM4 optic in QSFP28 ports that accept CWDM4 transceivers.

The optic follows the 100G CWDM4 MSA and 100G CLR4 Alliance specification. Four NRZ lanes run on the CWDM grid at 1271, 1291, 1311 and 1331 nm, multiplex onto a single duplex LC single-mode pair, and support 2 km over G.652 SMF. The wavelength plan follows the coarse WDM spacing of ITU-T G.694.2 rather than the tighter LAN-WDM grid used by LR4 optics, which is what keeps the part inside the 2 km reach class. DML transmitters drive PIN receivers, transmit power sits in the standard CWDM4 range, and digital diagnostics monitor temperature, supply voltage, laser bias, and per-lane optical power through the SFF-8636 and SFF-8665 management interface. Commercial 0 to 70°C operating temperature matches the family baseline, and the QSFP28 form factor seats in any standard QSFP28 cage.

The underlying EdgeOptic 100G-QSFP28-2.1 hardware is rated for three traffic types: 100G Ethernet, 4x32G Fibre Channel, and OTU4. Nokia deployments built around this ordering code run the optic for 100G Ethernet links. If a span needs the Fibre Channel or OTU4 service on the same module, contact our sales team so the right part is matched to the application.

One ordering note matters with Nokia 100G optics. 3HE10552AA is the CWDM4 2 km single-mode part, using the CWDM grid at 1271 to 1331 nm. Nokia assigns adjacent 3HE ordering codes to other 100G reach classes and fiber types, and the exact code determines the wavelength plan, the reach, and whether the optic runs on single-mode or multimode fiber. CWDM4 also does not interoperate with the LAN-WDM grid used by longer-reach 100G optics. Confirm the ordering code against the link distance and the cabling already in place, verify port support against the chassis transceiver table for the specific platform, and keep single-mode fiber with a clean duplex LC termination at both ends of the span before deploying.
