The GLC-BX80-U-I is the upstream half of a Cisco 1000BASE-BX80 pair: a single-fiber Gigabit Ethernet SFP that transmits at 1490 nm (1480 to 1500 nm) and receives in the 1550 to 1620 nm window. A GLC-BX80-D-I sits at the other end of the strand, and the operating transmission range reaches 80 km over standard G.652 single-mode fiber.
The two ends use separate transmit wavelengths, which is how one strand carries both directions. Digital Optical Monitoring follows the SFF-8472 standard and tracks output power, input power, temperature, laser bias current and transceiver supply voltage. The module measures 8.5 x 13.4 x 56.5 mm (H x W x D) and typically weighs 75 grams or less.
Platform support is set in the Cisco SFP Compatibility Matrix, which covers a variety of Cisco networking equipment. For a shorter upstream link, the GLC-BX40-U-I 1000BASE-BX40-U industrial SFP covers 40 km on one strand. More optics can be found in Cisco interface cards.
