Description
Cisco SFP (mini-GBIC) Module – For Data Networking
Optical Network – 1 x LC/PC 1000BASE-BX40-U Network – Optical Fiber – Single-mode – Gigabit Ethernet – 1000BASE-BX40-U – Hot-swappable
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-X40-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.
