Optical Performance
-----------------------------------------
* Transmitter (TX): Features a 1310nm EML (Electro-absorption Modulated Laser) with a power range of -2.4 dBm (min) to 4 dBm (max).

* Receiver (RX): Uses a PIN photodiode with a sensitivity range of -6.4 dBm (min) to 4.5 dBm (max).

* Forward Error Correction (FEC): Host-side FEC support is required to achieve the full 2km transmission distance.
