? finisar corporation 03feb 201 6 rev c page 1 product specification fdb - 1032 - s fp + evaluation board for sfp/sfp+ / sfp28 overview finisar?s fdb - 1032- sfp + evaluation board is designed for testing and evaluating all sfp, sfp+ and sfp 28 transceiver s a s well as sfp wire ? active optical cables . this i s not a module compliance board, bu t it is compatible with msa compliant sfp, sfp + and sfp 28 transceivers . contents the board consists of a single sfp 28 edge connector and sfp 28 cage assembly , four 50- ohm sm a female coaxial connectors ( j1 5 - j1 8 ) for the high - s peed differential transmitter input and receiver out put signals, and test points for monitoring the following pins: module rx_los module rx rate select 0 module tx rate select 1 module absent twi (two wire interface) scl and sda tx disable tx fault eval board ground and vcc module vcc rx and tx module ground case ground the evaluation board has led?s for the : rx_los rx rate select 0 tx rate select 1 module absent twi ? sda and scl ( low ) tx disable tx fault e val board power 5v eval board power 3.3v customized finisar software that is specific to this product is available. please contact your local finisar representative for details. the gui needs to be installed on a win dows ? xp or 7 operating system ( 32bit or 64bit machine ) that has an available usb port. the usb (type b) port is on the daughter card ( called a fdb - int - usb3 ) .
? finisar corporation 03feb 201 6 rev c page 2 specifications the fdb - 1032 - sfp+ evaluation board has several different power option s: ? a laboratory grade power supply with a voltage of 3.3 v dc at a maximum of 1. 2a at ?eval_vcc? ( j12) ; set s7 to ? 5v reg ? . set s8 to ?combined?. this will use the one power supply to power the eval board and the sfp. note that there will be a voltage drop at the sfp due to a diode that protects against accidental reverse voltages. it is recommended to measure the vcc to the sfp at the ?mod_vcc? tap near the sfp cage to make sure it is within operating limits . this power drop can be avoided in this setting by attaching the power supply to mod_vcc (j14), but the voltage protection will also be avoided. ? a n 8 - 20vdc source (e.g. laptop power supply) at j7; set s7 to ?5v reg?. set s8 to ?combined?. this is the recommended configuration . the eval board has reverse voltage protection and is fused ag ainst shorts, but there is no voltage drop at the sfp connector. the jumper - hook labeled 8 - 20vdc and the ground pin next to it, may also be used in this configuration . ? a laboratory grade power supply with a voltage of 3.3vdc at a maximum of 1.2a at ?mod ule_vcc? ( j1 4) ; set s7 to ?5v usb?. set s8 to ?separate?. this will use the power supply to power the sfp alone and have the eval board powered by the usb. there is no reverse voltage protection diode on this supply input. ? for class 1 (1w max) sfp/sf p+/ sfp28 power applications, power via usb. set s7 to ? 5v usb ? . set s8 to ?combined?. this will use the usb voltage for the eval board as well as the sfp. it is recommended to measure the vcc to the sfp at ?mod_vcc ? near the sfp cage to make sure it is within operating limits. note that the msa compliant pi filter will still be used for the sfp port in any of the above configuration s. the high speed lines are designed so there is <1ps skew between each different ial pair. the standard sm a connectors used for the high speed differential pairs are female. manual mode operation if the gui interface is not used , the eval board can still be used in manual mode, where it can serve as a test platform for the sfp, sfp+ or sfp 28 module to be mounted . set slider switches, s4, s5 and s6 to the ?sw? position, which is toward the sfp cage . for the twi (two wire interface) , use the taps that are labeled ?mod sda? and ?mod scl ? near the leds . the other twi taps are for internal use only. automated control mode operation for gui controlled operation s et slider switches s 4 , s 5 , and s 6 to the ?pc? position, away from the sfp cage. launch the gui called transceiver workbench sfp msa. this gui will give you access to the ddm (digital diagnostic monitors) as well as let you see and control masks for the alarms and warnings. gui installation please contact finisar for the required driver and software gui. s ee the datasheet (fdb - int - usb3) for the installation of the drivers necessary for the usb connection. once the eval board is ?seen? by the machine, the gui can be installed. copy the folder ? transceiver_workbench_ sfp _ customer_x.x.xx? to the computer ? s hard drive. find the executable file ? tr ansceiver_workbench_ sfp _msa. exe ? and run this application.
? finisar corporation 03feb 201 6 rev c page 3 notes the rest of the connectors, pins, tap points, headers and ic?s are for finisar internal use only. there is one momentary switch on the daughter card of the eval board. this is a manual reset of the twi. figure 1 below shows the locations of important points mentioned in this datasheet. figure 2 below shows test point s and leds. figure 1. top view of fdb - 1032- sfp+ 8 - 20vdc power connection slider (red/blue) and toggle (white) switches fdb - int - usb - 3 board with usb type b port 3.3 v module vcc tx fe male sma connectors rx fe male sma connectors sfp/sfp+/sfp28 port twi reset button 3.3v eval vcc
