- Flexible Customization Support
- Tested for Reliable Performance
- Fast Response & Delivery
- Professional Technical Support
The FC-LINK SFP+ 10G CWDM (1270-1450nm) ER LC DX series optical transceiver is designed for high-performance fiber communication applications, such as 10G Ethernet (10GBASE-ZR/ZW), and is fully compliant with the SFP+ MSA SFF-8431 specification. This module is optimized for single-mode fiber and operates across CWDM wavelengths, with ten available center wavelengths ranging from 1270nm to 1450nm, spaced 20nm apart. It offers a guaranteed optical link budget of 23dB. The module features an SFP+ connector for hot-plug capability and requires only a single 3.3V power supply. The optical output can be disabled via an LVTTL logic high-level input (TX_DIS), and a Loss of Signal (RX_LOS) output is provided to indicate the absence of an optical signal at the receiver.

| 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 4.7K~10 K 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 on host board. 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) The module signal ground contacts, VeeR and VeeT, should be isolated from the module case. 6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be between 370 and 700 Mv differential (185–350Mv single ended) when properly terminated. 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. Recommended host board power supply filtering is shown below. 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 internally connected within the SFP+ transceiver module. 8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board. |
