NOKIA (Alcatel) compatible 3FE25772AB Description
EdgeOptic's 3FE25772AB compatible is a Nokia-coded version of the EdgeOptic BiDi-1.25G-SFP-21-BD multi-vendor 1.25G BiDi SFP transceiver, coded for the downstream (B) side of a single-fiber link. It transmits at 1490nm and receives at 1310nm over a single LC fiber, with a 20km reach on a 15dB optical link budget. The design uses a DFB laser and PIN photodiode, with transmit power from −9 to 3 dBm, receiver sensitivity of −22 dBm and an overload point of −3 dBm. Transmit and receive bandwidths span 40nm windows, 1470 to 1510nm and 1290 to 1330nm, with chromatic dispersion tolerance of 430 to 500 ps/nm.
The module operates from 0 to 70°C at 3.3V and includes digital diagnostic monitoring per SFF-8472, reporting temperature, voltage, bias current, and transmit and receive optical power. It carries CE and RoHS marking, Class 1 laser safety per FDA regulations and IEC 60825-1, and follows the INF-8074i and SFP MSA mechanical and electrical specifications. Reseller catalogs also list an industrial-temperature, -40 to +85°C, variant of this SKU class. EdgeOptic's compatible ships to the standard 0 to 70°C commercial specification described here, not the industrial variant.
As the downstream half of the BiDi pair, 3FE25772AB is built to link with 3FE25772AA at the far end, which transmits at 1310nm and receives at 1490nm. Both modules install at opposite ends of the same single fiber, not the same end. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, this module ships with a lifetime warranty.

Frequently Asked Questions
Is the Nokia 3FE25772AB the same module as the 3FE25772AA?
No. The 3FE25772AB is the downstream (B) side of a Nokia BiDi single-fiber pair, transmitting at 1490nm and receiving at 1310nm. The 3FE25772AA is the upstream (A) side, transmitting at 1310nm and receiving at 1490nm. They are two ends of the same link, not interchangeable; installing two modules of the same side on one fiber run will not establish a link.
Which module pairs with the Nokia 3FE25772AB at the far end of the link?
3FE25772AB transmits at 1490nm and receives at 1310nm, so the module at the opposite end of the fiber must transmit at 1310nm and receive at 1490nm. Reseller catalogs pair 3FE25772AB with 3FE25772AA for that role.
Is the 3FE25772AB available in an industrial-temperature variant?
Reseller catalogs list an industrial-temperature, -40 to +85°C, variant of the 3FE25772AB class alongside the standard version. EdgeOptic's compatible ships to the standard 0 to 70°C commercial specification; it is not the industrial-temperature build. Contact our sales team if an extended-temperature version is required for the deployment.
