M120 Compact FPCs (CFPCs) Description
A CFPC is a combination of a PIC and an FPC. It contains the interface circuitry and the FPC as a single assembly. Two CFPCs are available for the M120 router: a 10-Gigabit Ethernet CFPC and an OC192 CFPC. Each CFPC is rated at 10 Gbps full duplex. Both CFPCs provide receptacles for XFP optical transceivers. The WAN interface enables interconnection directly to SONET transport facilities, eliminating the need for a separate SONET interface device. The M120 chassis provides two slots for CFPCs, and supports any combination of the two CFPC types. The CFPC slots feature a smaller form factor than the Type 1, 2, and 3 FPC slots, to provide higher density for M120 10-Gigabit interfaces.
Up to two Compact FPCs (CFPCs) install vertically in the front of the router (see FPC and CFPCs Installed in Router Chassis). The CFPC slots are numbered top to bottom CFPC0 and CFPC1. A CFPC can be installed in the two vertical slots on the left side of the chassis. Each CFPC weighs approximately 2 lbs. (0.9 kg.).
Figure 1 shows the Ethernet 10GBase XFP CFPC that the M120 router supports.

CFPC Components
Both CFPC types consist of the following components:
- CFPC card carrier.
- Midplane connectors and power circuitry.
- Processor subsystem, which includes a 667-MHz CPU, system controller, 128 MB of SDRAM, and two Fast Ethernet links to the Control Board.
- Crosspoint switches for redundancy.
- A metal bracket that enhances airflow and serves as a guide for removing and installing the CFPC.
- An LED located on the CFPC faceplate that displays the status of the CFPC.
The 10-Gigabit Ethernet CFPC also contains the following components:
- S2H FPGA—Bridge between HSL2 and one SPI-4.2 interface.
- 10GE MAC interface circuitry.
- XFP optical transceiver (LAN/WAN PHY).
The OC192 CFPC also contains the following components:
- H2H FPGA—Bridge between HSLA and HSL1 interface.
- Juniper Networks D4P framer.
- XFP optical transceiver.
