feature monitors five key transceiver parameters which are internally calibrated
and should be read as absolute values and interpreted as follows:
temperature and voltage range.

of nominal value over the specified operating temperature and voltage ranges.
range of 0 – 131 mA. Accuracy is ± 10 percent of nominal value over the specified
operating temperature and voltage ranges.

4.1
The JSH-01LWAx1 optical transceiver is equipped with a two-wire serial EEPROM
that is used to store specific information about the type and identification of the
transceiver as well as real-time digitized information relating to the transceiver’s
performance. See the Small Form Factor Committee document number SFF-8472

Transceiver Temperature in degrees Celsius:
a 16 bit signed two’s complement value in increments of 1/256°C from -40 to
+85°C with LSB equal to 1/256°C. Accuracy is ± 3°C over the specified operating
vcc/Supply voltage in volts:
integer with the voltage defined as the full 16-bit value(0 – 65535) with LSB equal
TX Bias Current in mA:
as the full 16-bit value (0 – 65535) with LSB equal to 2 uA with a measurement
TX Output Power in mw:
defined as the full 16-bit value (0 – 65535) with LSB equal to 0.1 uW. Accuracy is
