The module is intended to be used on the host board of system integrators to support transmission over
DWDM links in Metro networks. As shown in Figure 1-1, 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 LNK-OM8769XX200 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.

The CFP2 module is designed to be inserted into a host board with a railing system that includes a heat
sink. The module is 107.5 mm x 41.5 mm x 12.4 mm in size and is mechanically compliant with the
requirements detailed in the CFP2 HW Baseline Design Rev.1L.
The optical port connections on the front of CFP2 are shown in the Figure 8-1. The CFP2 module will
support LC receptacles for standard single mode fiber. As mention in the OIF-CFP2-DCO-01.0, the
position of the optical connector in the Y and Z axes shall be specified by the CFP2-DCO module
manufacturer. In addition to the centered duplex LC connector location specified by the CFP MSA, the
CFP2-DCO IA also optionally allows the optical port position on the front of the module to be either left or
right-justified if needed to enable a certain vendor-specific implementation technology.
Please check whether the cage matches before using the module because of the side has dissipation
hole structure. For example, the cage part CN121C-104-0029(H1) (YAMAICHI) has side openings
and a side without sharp protrusions.
