FVB-006 Evaluation Board Description: The FVB-006 Evaluation Board from Fiberxon is specifically designed to test and evaluate the optical Small Form Factor (SFF) transceiver modules for data rates from 100Mbps up to 2.5Gbps. The FVB-006 Evaluation Board accepts both the pins of a 2x5 or 2x10 SFF optical transceiever. The FVB-006 Evaluation Board provides four 50 Ohm SMA coaxial connectors (J1-J4) for the high-speed differential transmitter input signals (TX+, TX-) and receiver output signals (RX+, RX-). If SFF transceiver contains CDR module, other two 50 Ohm SMA coaxial connectors (J5, J6) are provided for the recovery clock signals (CLK+, CLK-). All high-speed inputs and outputs are transmitted by 50 Ohm transmission line on the top of the PCB. The FVB-006 board has a single power supply connection (J8), of which the power side must be supplied with 3.3V ±5% and the other side should be connected to ground. An LED (D2) indicates the power supply. J11, J12 allow separate powering of transmitter and receiver sections. An LED (D1) indicates the Signal Detect output of the module. As normal operation, Logic "1" outputs and the LED will light. For applications of 622Mbps and below, a converting circuit is designed to convert the PECL SD signal to TTL level. Two jumpers (J9, J19) are provided for this circuit selection. A switch is provided to assers and test the transmit disable function (S2). A resistor (R1), supplied photocurrent is connected to positive voltage supply and may be used to monitor received power. The current that flows into this pin is the received photocurrent. Considering the range of the received power, the value of the resistor is 2K. TP1 are provided to test the analog voltage output Vpd, which is proportional to the photo detector bias per the following formula: Ipd = (Vcc - Vpd)/2K. FVB-006 Evaluation Board Features:
