NOKIA (Alcatel) compatible SFP-GIG-BX-D20 Description
EdgeOptic's SFP-GIG-BX-D20 compatible is an Alcatel-Lucent Enterprise-coded version of the EdgeOptic BiDi-1.25G-SFP-21-BD multi-vendor 1000BASE-BX single-fiber BiDi SFP transceiver. ALE's OmniSwitch transceivers guides classify SFP-GIG-BX-D20 as 1000BASE-BX20, ALE's own 20 km reach label, matching the EdgeOptic module's 20 km reach and 15 dB link budget directly. IEEE 802.3ah defines only the 10 km BX10 class; 1000BASE-BX20 is ALE's own vendor label, not an IEEE clause number.
On the wire, the D20 side transmits at 1490 nm and receives at 1310 nm over a single strand of single mode fiber, using a DFB laser and a PIN photodiode. Transmit power runs −9 to 3 dBm, receive sensitivity is −22 dBm, and the overload point is −3 dBm, yielding the 15 dB link budget. Guaranteed bandwidth is 1470 to 1510 nm on transmit and 1290 to 1330 nm on receive, with dispersion tolerance of 430 to 500 ps/nm. Operating range is 0 to 70°C at 3.3V, with DDM per SFF-8472.
SFP-GIG-BX-D20 pairs at the far end with SFP-GIG-BX-U20, not the base SFP-GIG-BX-U code. EdgeOptic sells the matching SFP-GIG-BX-U20 compatible for the opposite end of the link. SFP-GIG-BX-D20 belongs to ALE's 1G Gigabit Ethernet BiDi family; ALE's 10G BiDi optics use different vendor part numbers, so a bill of materials calling for a 10G BX D20 module does not match this SKU. Connector type is LC, with CE, RoHS and Class 1 laser safety compliance per FDA/IEC 60825-1. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the compatible ships with a lifetime warranty.

Frequently Asked Questions
Is the SFP-GIG-BX-D20 a 10 km or a 20 km module?
ALE's own OmniSwitch transceivers guides classify SFP-GIG-BX-D20 under Connections Supported as 1000BASE-BX20, ALE's 20 km reach class label. This module reaches 20 km with a 15 dB link budget, matching ALE's own classification exactly.
Which far-end module pairs with the SFP-GIG-BX-D20?
ALE documents SFP-GIG-BX-D20 as pairing with SFP-GIG-BX-U20 at the far end, not the base SFP-GIG-BX-U code. EdgeOptic sells the matching SFP-GIG-BX-U20 compatible for the opposite end of the link.
Is the SFP-GIG-BX-D20 a 1G or 10G module?
SFP-GIG-BX-D20 is part of ALE's 1G Gigabit Ethernet BiDi family; the module operates at a maximum data rate of 1.25 Gbps. ALE's 10G single-fiber BiDi optics use different vendor part numbers, so a bill of materials calling for a 10G BX D20 module does not match this SKU.
