The LNK-OM8668XX100 module uses a 148-pin OIF MSA connector for all electrical interfaces with the
host card, whereas the optical interfaces on the line side are provided through the optical receptacles
on the CFP. As depicted in Figure 2-1, the module can be portioned into four parts: oDSP, optical
component, control unit and power block.

● Transmission reach beyond 1300 km for 200G and 3000 km
for 100G over SMF without inline chromatic dispersion
compensation
● Hot-pluggable
● Supports PM-DQPSK (100G), PM-QPSK (100G) and PM-
16QAM (200G) modulation
● Supports 50 GHz channel spacing
● Supports SD-FEC
● Support OTU4, OTUC2, compliant with
OTL4.10/OTL4.4/OTLC2 signaling
● Compliant with CFP MSA CFP Hardware Specification 1.4
with modifications
● Compliant with CFP MSA Management Interface
Specification 2.6 with modifications
● Framed PRBS generator/checker on the host and network
side interfaces
● SerDes PRBS generator/checker for per lane testing of host
interface
● LC optical receptacle
● Operating case temperature: 0°C to 70°C
● Power consumption: 32 W

The module is designed to be used on the host board of system integrators to support transmission over
DWDM links in Metro/Long-haul networks. As shown in Figure 1-1, it comprises of high-data lanes, a
single reference clock for OTUCn hosts, a single 3.3 V power supply, an MDIO interface for module
1. Application
control and status report, and dedicated alarm and control pins.

The CFP module is designed to be inserted into a host board with a railing system that includes a heat
sink. The module is 144.75 mm x 75.00 mm x 13.60 mm in size and is mechanically compliant with the
requirements detailed the CFP Hardware Specification rev.1.4 (with modifications, added heat dissipation
holes).
A mechanical model is available from E-link upon request.
