General Description
LACF-0429-LR is the optical transceiver module which is a hot pluggable form factor designed for high speed optical networking application. It is designed for 100 Gigabit Ethernet application and provides 100GBASE-LR4 compliant optical interface, CAUI electrical interface and MDIO module management interface. LACF-0429-LR converts 10-lane 10.3Gb/s electrical data streams to 4-lane LAN-WDM 25.78Gb/s optical output signal and 4-lane LAN-WDM 25.78Gb/s optical input signal to 10-lane 10.3Gb/s electrical data streams. This 10-lane 10.3Gb/s electrical signal is fully compliant with IEEE 802.3ba CAUI specification. The high performance Cooled LAN-WDM EA-DFB transmitter and high sensitivity PIN receiver provide superior performance for 100Gigabit Ethernet applications up to 10km links and compliant optical interface with IEEE802.3ba 100GBASE-LR4 requirements.
The LACF-0429-LR contains a duplex LC connector for the optical interface and a 148-pin connector for the electrical interface. Figure 1 shows the functional block diagram of LACF-0429-LR.

Figure 1. CFP LR4 Optical Transceiver functional block diagram
Transmitter
The transceiver module receives 10-lane 10.3 Gb/s CAUI electrical inputs. The gearbox multiplexes 10-lane electrical signals to 4-lane electrical signals. The multiplexed 4-lane signals are fed to the transmitters. The four transmitters convert 4-lane signals to an optical signal through 4 Laser drivers and Lasers diodes which are packaged in the Transmitter Optical Sub-Assembly (TOSA). Each Laser launches optical signal in specific wavelength specified in IEEE802.3ba 100GBASE-LR4 requirements. These 4-lane optical signals will be optically multiplexed into one fiber by 4 to1 Optical WDM MUX which is in the TOSA. The optical output power is held constant by an automatic power control (APC) circuit. The transmitters output can be turned off by TX_DIS hardware signal and/or through MDIO module management Interface.

Receiver
The LACF-0429-LR receives 4-lane LAN WDM optical signals. The optical signals are de-multiplexed by 1 to 4 optical DE-MUX and fed into each Receiver Optical Sub-Assembly(ROSA)integrated 1:4 optical DE-MUX. The ROSA converts optical signal to electrical signal. The 4-lane regenerated electrical signals are de-multiplex to 10-lane signals by the 4 to 10 gearbox. The 10-lane signals are compliant with IEEE CAUI interface requirements. Each received optical signal is monitored by the DOM section. The monitored value is reported through the MDIO section. If one or more received optical signal is weaker than the threshold level, RX_LOS hardware alarm will be launched.

MDIO Management Interface

The LACF-0429-LR supports the MDIO interface specified in IEEE802.3 Clause 45. This 2-wire management data I/O interface is provided for the module status monitoring and control. The management data clock (MDC) provides clocking for the data that is passed on the MDIO port. Five further pins allow for loading of a port address (PORT_ADDR0-4) into the module. The CFP transceiver supports MDIO pages 8000h NVR 1 Based ID registers, 8080h NVR 2 Extended ID registers, 8100h NVR 3 network lane specific registers , and pages A000h CFP module VR 1 registers,A080h MLG VR 1 registers, A200h network lane VR 1 registers,A280h network lane VR 2 registers.
Details of the protocol and interface are explicitly described in CFP MSA Management Interface Specification. Please refer to the specifications for design reference.
