OM8769XX200 is intended to be used on the host board of system integrators to support transmission over DWDM links in Metro networks. It comprises high-data lanes, a single reference clock from hosts, a single 3.3 V power supply, an MDIO interface, and dedicated alarm and control pins. The module uses a 104-pin CFP2 MSA connector for all electrical interfaces with the host board, whereas the optical interfaces on the line side are provided through the optical receptacles on the CFP2. The module can be portioned into three functional parts: Tx path, Rx path and control & power block. All control interface pins are routed to the MCU and oDSP. The MCU is also used for fast control inside the module such as modulator bias adjustment, firmware management, overall control coordination and status reporting.
