- Specifications
The SFP-10G-BX40U-I is the upstream end of a Cisco 10GBASE-BX40 link, a bidirectional SFP+ module for 40 km over one strand of standard single-mode fiber (G.652). It always pairs with an SFP-10G-BX40D-I over a single strand, and the pair reaches up to 40 km.
This upstream module transmits at 1270 nm and receives a 1330 nm signal, the reverse of its downstream partner. Its transmit window runs from 1260 to 1280 nm and its receive window from 1320 to 1340 nm.
Digital Optical Monitoring is supported under the SFF-8472 MSA, with readings of optical output power, optical input power, temperature, laser bias current and transceiver supply voltage. Power consumption is 1.2 W and the module belongs to the industrial temperature (IND) class, and its color code is red. Additional transceivers are in the Cisco interface card category.
