Cisco compatible GLC-BX80-D-I Description

EdgeOptic's GLC-BX80-D-I compatible is a Cisco-coded version of the EdgeOptic 1.25G BiDi SFP 80km Industrial Transceiver (Side B), a multi-vendor Gigabit Ethernet BiDi SFP for single-fiber links up to 80 km. Cisco documents that a GLC-BX80-D-I device is always connected to a GLC-BX80-U-I device over a single strand of standard single-mode fiber, with an operating range up to 80 km, so order the two part numbers as a matched pair. EdgeOptic also carries a compatible for the GLC-BX80-U-I Side A unit that completes this link.

The module uses a DFB laser transmitting at 1550 nm and a PIN photodiode receiving at 1490 nm, rated at a 22 dB average link budget over an industrial operating range of -45 degrees C to +85 degrees C. Minimum transmit power is -2 dBm and maximum transmit power is 3 dBm, with -24 dBm receiver sensitivity and -3 dBm receiver overload. Dispersion tolerance is rated 1600 to 1700 ps/nm across the 1.063 to 1.25 Gbps supported data rate for Gigabit Ethernet applications. DDM/DOM diagnostics are supported for real time Tx power, Rx power, bias current, voltage and temperature monitoring. The interface uses a single LC/UPC connector and runs on a single 3.3V power supply.

EdgeOptic codes the GLC-BX80-D-I compatible to the Cisco ordering code referenced above. Cisco transceiver recognition and third-party optic acceptance vary by platform and software release, so verify against Cisco's own compatibility matrix for the target platform before deployment.

Backed by EdgeOptic's compatibility engineering across vendor optical platforms, this part is made to order with a 2-week lead time and includes EdgeOptic's lifetime warranty. For project-quantity pricing or an alternate vendor coding, contact our sales team.

Frequently Asked Questions

Does the GLC-BX80-D-I need to be paired with a GLC-BX80-U-I on the other end of the link?

Yes. Cisco documents that a GLC-BX80-D-I device is always connected to a GLC-BX80-U-I device over a single strand of standard single-mode fiber, with an operating range up to 80 km. The Side D and Side U part numbers use different transmit and receive wavelengths, so they only interoperate as a matched pair. EdgeOptic offers a compatible for the GLC-BX80-U-I unit needed to complete the link.

Is GLC-BX80-D-I= a different part than GLC-BX80-D-I?

No. The trailing equals sign in Cisco's part numbering is a spare orderable indicator, not a separate hardware revision. GLC-BX80-D-I and GLC-BX80-D-I= identify the same transceiver.
