Cisco GLC-BX40-D-I= 1000BASE-BX40-D SFP Transceiver Module, SMF 1550nm, DOM Max 40Km
Product Specifications
1000BASE-BX40-D and 1000BASE-BX40-U for single-fiber bidirectional applications
The Cisco GLC-BX40-D-I, GLC-BX40-DA-I, and GLC-BX40-U-I SFPs operate on a single strand of standard SMF.
A GLC-BX40-D-I or GLC-BX40-DA-I device connects to a GLC-BX40-U-I device with a single strand of standard SMF with an operating transmission range up to 40 km.
The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. The GLC-BX40-D-I, GLC-BX40-DA-I, and GLC-BX40-U-I SFPs also support Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
1000BASE-BX80-D and 1000BASE-BX80-U for single-fiber bidirectional applications
The Cisco GLC-BX80-D-I and GLC-BX80-U-I SFPs operate on a single strand of standard SMF.
A GLC-BX80-D-I device is always connected to a GLC-BX80-U-I device with a single strand of standard SMF with an operating transmission range up to 80 km.
The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. The GLC-BX80-D-I and GLC-BX80-U-I SFPs also support Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
Optical specifications
Table 2 specifies the optical parameters for the SFPs. Both receiver power and channel insertion loss specifications must be met for guaranteed operation.

GLC-BX40-DA-I | -5 to +3 | -25 to +3 | 19 (G.652 SMF) | 1480 to 1500 (Transmit) 1260 to 1360 (Receive) |
GLC-BX40-U-I | -5 to +3 | -25 to +3 | 19 (G.652 SMF) | 1260 to 1360 (Transmit) 1480 to 1600 (Receive) |
GLC-BX80-D-I | -2 to +3 | -27 to +3 | 23 (G.652 SMF) | 1560 to 1580 (Transmit) 1470 to 1510 (Receive) |
GLC-BX80-U-I | -2 to +3 | -27 to +3 | 23 (G.652 SMF) | 1480 to 1500 (Transmit) 1550 to 1620 (Receive) |
* Maximum channel insertion loss is defined for maximum distance guaranteed as specified in Table 1 and by fiber type. When links are deployed over shorter distances, additional channel insertion loss may be allowed.
