FDB-1027 Finisar

Product Specification SFP/SFP+ Evaluation Board FDB-1027 Serial ID information available in Finisars SFP/SFP+ transceivers. Switch (S1) is provided to assert and test the transmit disable function. Switch (S2) is provided to select the operating bit rate of the receiver (RS0) in multi-rate SFP/SFP+ transceivers that require it. Switch (S3) is provided to select the operating bit rate of the transmitter (RS1) in multi-rate SFP+ transceivers that require it. (Note: SFP modules do not support RS1.) TX disable can be controlled either by the switch or the parallel port control is determined by the position of the Finisars FDB-1027 Evaluation Board is the jumper (S4). Similarly, jumpers at (S5) and (S6) perfect vehicle for testing and evaluating govern the RS0 and RS1 controls, respectively. SFP/SFP+ optical transceivers. SPECIFICATIONS The board consists of a single SFP+ edge The FDB-1027 SFP/SFP+ Evaluation Board can connector and cage, four 50-ohm SMA coaxial be powered by one or two supply voltage(s) connectors (J12-J15) for the high-speed depending on whether the supply for the differential transmitter input and receiver output evaluation board and module need to be signals, and test points and LEDs for monitoring separated. A module supply voltage of 3.0 to all other SFP+ pins. It is compatible with short 3.6V should be supplied at connector J9. If wavelength and long wavelength SFP/SFP+ shunt at jumper J2 is removed, a second 3.3V transceiver types for use at data rates of supply can be provided at J1 to separately power 125 Mb/s to 14.025 Gb/s. the evaluation board. The FDB-1027 SFP/SFP+ Evaluation Board is Please refer to module data sheets for supplied with software and a DB-25 cable for specifications of input signals to the TX+ and communication with a PC parallel port. This TX connectors and output signals on the RX+ cable allows direct communication between the and RX connectors. SFP/SFP+ transceivers PC and the module via the 2-wire serial bus on have internal AC coupling on all data lines. pins SCL and SDA, as well as for reading the status lines and setting the TX disable and Rate The board layout and schematics are shown on Select inputs. pages 2 and 3.
