Note: 

  1. TX Fault is an open collector/drain output, which should be pulled up with a 4.7K–10KΩ resistor on the host board. Pull up voltage between 2.0V to VccT+0.3V or VccR+0.3V. High output indicates a laser fault of some kinds. Low indicates normal operation. In the low state, the output voltage will be below 0.8V.
  2. TX disable is an input that is used to control the transmitter power output. It is pulled up within the module with a 4.7–10 KΩ resistor. Its states are: Low (0 – 0.8V): Transmitter on; (>0.8, < 2.0V):

Undefined; High (2.0 – Vcc): Transmitter Disabled Open: Transmitter Disabled

  1. These pins should be pulled up with a 4.7K –10KΩ resistor on the host board. The pull-up voltage

shall be VccT or VccR. Mod-Def 0 is grounded by the module to indicate that the module is present.

  1. RSSI TRIG is a LVTTL input. Assert high after 500ns delay time of the beginning of the monitored burst package,at least 500ns in duration.
  2. LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor to VccT +0.3V or VccR+0.3V. Low level indicates that burst packet is detected by the

receiver.  

  1. RD-/+: These are the differential receiver outputs. They are DC coupled 100Ω differential line

which should be terminated with 100Ω (differential) at the user SER.DES.

  1. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP connector pin. Maximum supply current is 400mA. Recommended host board power supply

filtering is shown interface circuit. Inductors with DC resistance of less than 1Ω, in order to insure the voltage at the SFP input pin with 3.3V. When the recommended supply filtering network is used, hot plugging of the SFP transceiver module will result in an inrush current of no more than 30 mA greater than the steady state value. VccR and VccT may be internally connected within the SFP transceiver

module.

  1. TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with100Ω differential termination inside the module. The AC coupling is done inside the module and is

thus not required on the host board.
