 25G SFP28 DWDM 10km Transceiver RDSFP28-XX25G-L1D

Product description

Rollball’s RDSFP28-XX25G-L1D 25Gb/s DWDM SFP28 transceiver is designed for use in 25-Gigabit Ethernet links up to 10km over single mode fiber. The module consists of DWDM EML Laser, APD and Preamplifier in a high-integrated optical sub-assembly. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.This module is designed for single mode fiber and operates at a nominal wavelength of 100GHz ITU Grid, C Band DWDM wavelength.

The module optical connection is duplex LC and shall be compatible with SFP+ 28Gbps and backward compatible with legacy 10G SFP+ pluggable. The SFP28 DWDM LR module is a dual directional device with a transmitter and receiver plus a control management interface (2-wire interface) in the same physical package. 2-wire interface is used for serial ID, digital diagnostics and module control function.

The transmitter converts 25Gbit/s serial PECL or CML electrical data into serial optical data compliant with the 25GBASE-LR standard.  An open collector compatible Transmit Disable (Tx_Dis) is provided.  Logic “1” or no connection on this pin will disable the laser from transmitting.  Logic “0” on this pin provides normal operation.
