SFP+LR DWDM Transceiver is a ”Limiting module”, designed for 10GBASE-LR, and 2G/4G/8G/10G Fiber-Channel applications.

The transceiver consists of two sections: The transmitter section incorporates a DFB laser. And the receiver section consists of a PIN photodiode integrated with a TIA. All modules satisfy class I laser safety requirements. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power, and transceiver supply voltage.

  • The module circuit ground is isolated from the module chassis ground within the module.
  • Should be pulled up with 4.7k-10k ohms on the host board to a voltage between 3.15V and 3.6V.
  • Tx_Disable is an input contact with a 4.7 kΩto 10kΩ pull up to VccT inside the module.
  • Mod_ABS is connected to VEET or VEER in the SFP+ module. The host may pull this contact up to Vcc_Host with a resistor in the range of 4.7 kΩ to 10 kΩ Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot.
  • RS0 and RS1 are module inputs and are pulled low to VEET with > 30 kΩ resistors in the module.
