The transceiver consists of two sections: The high performance a 1310nm DFB Laser, Transmitter and high sensitivity PIN integrated with a TIA. Receiver.
A block diagram of the HSFP10-2323 SFP+ optical transceiver is shown below.
The module is hot pluggable into the 20-pin connector. The high-speed electrical interface is based on low voltage logic, with nominal 100 Ohms differential impedance and AC coupled in the module. The optical output can be disabled by LVTTL logic high-level input of TX_Disable. Loss of signal (RX_LOS) output is provided to indicate the loss of an input optical signal of receiver. The receiver RATE_SELECT pin is not used by the transceiver.
A 2-wire interface (SCL, SDA) is used for serial ID, digital diagnostics and other control /monitor functions.

Note 1. TD+/- are internally AC coupled with 100Ω differential termination inside the module.
Note 2. Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V.
Note 3. RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES.
