The FC-LINK SFP+ 10G CWDM (1270-1610nm) LR LC DX series optical transceiver is specifically designed for fiber communication applications such as 10G Ethernet (10GBASE-LR/LW). Fully compliant with the SFP+ MSA specification SFF-8431, this module supports single-mode fiber operation at CWDM wavelengths, offering multiple center wavelengths ranging from 1270nm to 1610nm, with 20nm increments.Featuring an SFP+ connector for hot-plug capability, the module requires a single 3.3V power supply. Key functions include TX_DIS for disabling the optical output via LVTTL logic high input and RX_LOS to indicate the loss of an input optical signal. Additionally, it supports digital diagnostic monitoring via a 2-wire serial interface as per the SFF-8472 specification.

| Notes: 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 and VccT, R+0.3V. When high,output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8V. 2) . TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7-10K Ω resistor. Its states are: Low (0 - 0.8V): Transmitter on (>0.8, < 2.0V): Undefined High (2.0 - 3.465V):Transmitter Disabled Open: Transmitter Disabled 3)Module absent, connected to VEET or VEER in the module. 4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K–10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates the received optical power is below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V. 5) VeeR and VeeT may be internally connected within the SFP+ module. 6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with100Ω(differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board. 7) 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 300mA. Inductors with DC resistance of less than 1 ohm should be used in order to maintain the required voltage at the SFP+ input pin with 3.3V supply voltage. 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 30mA greater than the steady state value. VccR and VccT may be internall connected within the SFP+ transceiver module. 8) . TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100 differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board. |
