10/25GBASE-LR BiDirectional - U SFP28 iTemp Module

The Cisco 10GBASE-LR/10GBASE-BR/25GBASE-BR Module supports a link length of 10 kilometers on a single strand of standard Single-Mode Fiber (SMF) G.652 at both 10G and 25G. A SFP-10/25G-BXD-I device is always connected to a SFP-10/25G-BXU-I device with a single strand of standard SMF. The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. SFP-10/25G-BXD-I transmits at 1330nm channel and receives at 1270nm signal. The SFP-10/25G-BXU-I transmits at a 1270nm wavelength and receives a 1330nm signal.

The module requires RS-FEC on the host ports for full reach operation at 25G. This module has an industrial temperature range. This module also supports CPRI datarates options 7, 8, 9 and 10.

In some applications using BASE-R FEC the module can support 3.5km and without FEC it can support 1.5km, depending on fiber quality.
