NOKIA (Alcatel) compatible 3AL82072AA Description
EdgeOptic's 3AL82072AA compatible is a Nokia-coded dual-rate QSFP28 transceiver built on our 100G-QSFP28-10 platform. The module supports both 100GBASE-LR4 Ethernet at 103.125 Gbps and OTU4 4l1-9D1F at 111.81 Gbps per ITU-T G.709, which is the differentiating capability versus the LR4-only 3HE10550AA. The 3AL-prefix is the legacy Alcatel-Lucent hardware ordering code that remains active in Nokia 7750 SR transceiver compatibility tables after the 2016 Nokia acquisition. Engineers will also see this module referenced internally by Nokia as q28lr4d.
The optical path uses LAN WDM with four channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, multiplexed within the 1310 nm window onto a single duplex LC fiber pair. Per-lane modulation is NRZ at 25.78125 Gbps for 100GbE and 27.9525 Gbps for OTU4. Transmitter is an EML array; receiver is a PIN photodiode array. Optical path loss budget is 6.3 dB per IEEE 802.3ba Clause 88, supporting up to 10 km over OS2 (G.652.D) single-mode fiber. Reach in the field depends on actual fiber attenuation and connector loss.
Digital optical monitoring (DDM/DOM) reports transmit and receive optical power, module temperature, laser bias current, and supply voltage through the SFF-8636 management interface. The module has no internal FEC; OTU4 generic FEC and Ethernet RS-FEC (IEEE 802.3bj Clause 91) are handled host-side in the platform ASIC. Host electrical interface is CAUI-4 (4x25G NRZ per IEEE 802.3bj Clause 83). Operating temperature is 0 to 70 °C. Power draw is typical 3.5 W; QSFP28 Class 4 cage budget is 4.5 W maximum per SFF-8665.
The module ships CE/RoHS certified and complies with QSFP28 MSA SFF-8665 and IEEE 802.3ba 100GBASE-LR4. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing or alternative vendor coding, contact our sales team.
Frequently Asked Questions
What is the difference between 3AL82072AA and 3AL82074AA?
3AL82072AA and 3AL82074AA are distinct Nokia ordering codes that appear in vendor catalogs as separate part numbers. 3AL82072AA is the dual-rate 100GBASE-LR4 / OTU4 module covered on this page. The 74AA variant is a related Nokia SKU; verify the target SR OS chassis transceiver table before ordering, since the platform compatibility list determines which code is the correct match.
Which Nokia platforms support 3AL82072AA?
Nokia 7750 SR is the confirmed platform family for 3AL82072AA. The OTU4 dual-rate capability is most commonly used on 7750 SR line cards that present 100G client interfaces and OTN tributaries from the same QSFP28 cage. Always check the chassis transceiver table for the specific MDA and SR OS release before deployment.
Does the compatible 3AL82072AA work natively on Nokia SR OS?
Yes. EdgeOptic codes the EEPROM with Nokia-recognized data, so SR OS reports the module as a vendor-supported 3AL82072AA. No allow-unsupported-transceiver or equivalent CLI override is required.
Does 3AL82072AA support OTU4 in addition to 100GbE?
Yes. 3AL82072AA is a dual-rate module. It carries 100GbE at 103.125 Gbps and OTU4 4l1-9D1F at 111.81 Gbps per ITU-T G.709 over the same LAN WDM optical interface. The host SR OS platform selects the operating mode based on the line card configuration.
What is the difference between 3AL82072AA (3AL-prefix) and 3HE10550AA (3HE-prefix)?
The prefixes reflect different eras of Nokia ordering codes. 3AL is the Alcatel-Lucent legacy hardware code, retained in Nokia catalogs after the 2016 acquisition. 3HE is Nokia's current hardware code. The two parts are not interchangeable specifications: 3AL82072AA is dual-rate 100GBASE-LR4 / OTU4, while 3HE10550AA is 100GBASE-LR4 only. Order based on whether OTN transport over OTU4 is required on the link.
