FDB-1032-SFP+

Product Specification FDB-1032-SFP+ Evaluation Board for SFP/SFP+/SFP28 OVERVIEW Finisar’s FDB-1032-SFP+ Evaluation Board is designed for testing and evaluating all SFP, SFP+ and SFP28 transceivers as well as SFPwire® Active Optical Cables. This is not a module compliance board, but it is compatible with MSA compliant SFP, SFP+ and SFP28 transceivers. CONTENTS The board consists of a single SFP28 edge connector and SFP28 cage assembly, four 50-ohm SMA female coaxial connectors (J15-J18) for the high-speed differential transmitter input and receiver output 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 Eval Board Power 5V Eval Board Power 3.3V © Finisar Corporation 03FEB2016 Rev C 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 Windows® 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).

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. • An 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 against 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 “Module_Vcc” (J14); 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/SFP+/ 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 © Finisar Corporation 03FEB2016 Rev C “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 configurations. The high speed lines are designed so there is
