As shown in Figure 1, the transmitter path of the transceiver contains an 4x25Gbps CAUI-4 electrical input with equalization (EQ) block, integrated electrical multiplexer, EML driver, EML lasers and diagnostic monitor. The transmitter section uses a wavelength of L-WDM EML, it’s a class 1 laser compliant according to International Safety Standard IEC 60825.
As shown in Figure 1, the optical receiver portion of the transceiver contains TAP-PD, VOA, SOA, four PDs, trans- impedance amplifiers (TIA), integrated de-multiplexer and CAUI-4 compliant electrical output blocks.
The high speed signal lines are internally AC-coupled and the electrical inputs are internally terminated to 100 Ohms differential.All transmitter and receiver electrical channels are compliant to module XLAUI/CAUI specifications per IEEE 802.3ba.
The module has the following low speed signals for control and status: ModSeL ModPrsL ResetL IntL/RxLOSL LPMode/TxDis. In addition, there is an industry standard two wire serial interface scaled for 3.3V LVCMOS. It is implemented as a slave device. Signal and timing characteristics are further defined in the Control Characteristics and Control Interface.
Exposure to current surges and overvoltage events can cause immediate damage to the transceiver module. Observe the precautions for normal operation of electrostatic discharge sensitive equipment; Attention shall also be paid to limiting transceiver module exposure to conditions beyond those specified in the absolute maximum ratings.
Optical connectors include female connectors. These elements will be exposed as long as the cable or port plug is not inserted. At this time, always pay attention to protection.
Each module is equipped with a port guard plug to protect the optical port. The protective plug shall always be in place whenever the optical fiber is not inserted. Before inserting the optical fiber, it is recommended to clean the end of the optical fiber connector to avoid contamination of the module optical port due to dirty connector. If contamination occurs, use standard LC port cleaning methods.

The PMD block diagram is shown in Figure3. For purposes of system conformance, the PMD sublayer is standardized at the points described in this subclause. The optical transmit signal is defined at the output end of a single-mode fiber patch cord (TP2), between 2 m and 5 m in length. Unless specified otherwise, all transmitter measurements and tests defined in IEEE 802.3 88.8 are made at TP2. The optical receive signal is defined at the output of the fiber optic cabling (TP3) at the MDI (see IEEE 802.3 88.11.3). Unless specified otherwise, all receiver measurements and tests defined in IEEE 802.3 88.8 are made at TP3.

1: GND is the symbol for signal and supply (power) common for the module. All are common within the module and all module voltages are referenced to this potential unless otherwise noted. Connect them directly to the host board signal-common ground plane. 2: VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and applied concurrently. VccRx, Vcc1 and VccTx are internally connected within the module in any combination. Vcc contacts in SFF- 8662 and SFF-8672 each have a steady state current rating of 1A. |
