Cisco 1000BASE-BX10-D network 1310 nm GLC-BX-D=

The industry-standard Cisco® Small Form-Factor Pluggable (SFP) Gigabit Interface Converter is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot. linking the port with the network. SFPs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-SX. 1000BASE-LX/LH. 1000BASE-ZX. or 1000BASE-BX10-D/U on a port-by-port basis. The 1000BASE-BX-D. compatible with the IEEE 802.3ah 1000BASE-BX10-D standard. operate on a single strand of standard SMF. A 1000BASE-BX10-D device is always connected to a 1000BASE-BX10-U device with a single strand of standard SMF with an operating transmission range up to 10 km. The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices: 1000BASE-BX10-D transmits a 1490-nm channel and receives a 1310-nm signal. whereas 1000BASE-BX10-U transmits at a 1310-nm wavelength and receives a 1490-nm signal. The GLC-BX-D SFP also support digital optical monitoring (DOM) functions according to the industry-standard SFF-8724 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.
