Nokia (Alcatel-Lucent) 3HE11239AA Compatible 100GBASE-ER4 Lite QSFP28 40km Module

EdgeOptic's 3HE11239AA compatible is a Nokia (Alcatel-Lucent) coded 100GBASE-ER4 Lite QSFP28 transceiver built on our 100G-QSFP28-40 hardware platform. The module ships pre-programmed with EEPROM values for the 3HE11239AA ordering code, so the optic identifies on the host as the OEM transceiver. This page covers the standard 40km LAN-WDM ER4 Lite variant only; the 3HE11239AA-IND industrial-temperature build and the 3HE11239AA-80 ZR4 80km variant are separate products and are not interchangeable with this SKU.

Optically the module conforms to the 100GBASE-ER4 Lite specification. Four LAN-WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm each carry 25.78125 Gbps NRZ, multiplexed onto one duplex LC single-mode fiber pair. Reach is 40km on G.652 SMF with host RS-FEC enabled (22 dB optical budget), and 30km on the same fiber without FEC (18 dB budget). The transmitter is an EML array; the receiver is an APD array, providing the additional sensitivity that distinguishes ER4 Lite from a standard LR4 PIN-receiver build. ER4 Lite is not an IEEE 802.3ba/bm subclause and is not part of the 100G Lambda MSA.

Host-side FEC is the gating requirement for the 40km reach. RS-FEC must be enabled on the connected port; the optic itself is transparent to FEC and contains no internal FEC engine. Without FEC the link will close at distances up to 30km on plant operating near the typical 0.35 dB/km attenuation budget. Engineers planning links between 30 and 40km should confirm the host port has RS-FEC available on the 100GE MAC and verify both ends match during commissioning. The optic is hot-pluggable and recognized by the Nokia host as the OEM 3HE11239AA transceiver.

QSFP28 MSA SFF-8665 and SFF-8636 management compliance covers the electrical and software interfaces. DDM/DOM telemetry exposes per-lane TX and RX optical power, module temperature, supply voltage and laser bias current to the host. The duplex LC connector accepts standard SMF patch cords. Power draw is bounded at 4.5 W; the commercial 0 to +70 degC case-temperature range covers central-office and metro POP environments. Connector hygiene matters at ER4 Lite reach budgets; inspect and clean both end-faces before turn-up to avoid attenuation that erodes the FEC margin.
