PRODUCT PRESENTATION
 
 

The JFOPT SFP+ BIDI 10G 1270/1330nm 20km ELR LC SX series single-mode transceiver is a compact, pluggable module designed for duplex optical data communication, supporting IEEE 802.3ae 10GBASE-LR/LW standards. It features a 20-pin SFP+ connector for hot-plug capability and is optimized for single-mode fiber, operating at nominal wavelengths of either 1270nm or 1330nm. The transmitter uses a multiple quantum well DFB laser, compliant with Class 1 laser safety standards according to IEC-60825. The receiver integrates an InGaAs detector preamplifier (IDP) within an optical header, paired with a limiting post-amplifier IC for robust signal processing.

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 KΩ 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) 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 350 and 700 mV differential (175 –350 mV 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 430mA. 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. The inputs will accept differential swings of 150 – 1200 mV (75 – 600mV single-ended).
