Notes:

[1] Two complementary signals of equal amplitude on each input.

[2] Referred to data level 20% or 80%, see diagram below for definitions.

[3] When not connected the TXDIS, CSEL inputs are considered in a low state, (internal pull-down resistor).

Clocked mode, CSEL=low is presently unsupported for the MT10EW.

[4] Time measured from rising edge of shutdown signal until optical output has turned off (<-40dBm).

[5] Time measured from falling edge of shutdown signal until optical output power is over 0dBm and emitted wavelength is at

nominal value +/- 200 pm. The unit is assumed to be powered on for at least 30s.

[6] Time measured from falling edge of shutdown signal until optical output power is within the specified range and

wavelength within +/-30pm.

The unit is assumed to be powered on for at least 30 seconds.

[7] Time measured from enabling laser until optical output power is within the specified range and wavelength within +/-120pm.

Module powered for 5 seconds minimum prior to enabling laser.

For any initial case temperature within the specified operational range and with TXDIS = off.

[8] Back facet monitor voltage is measured from pin 2 to GND and normalized at the beginning of life relative to the initial optical

output power (Tcase = 25°C, nominal power supply). The relationship is approximately linear, as represented by the equation:

Back-facet voltage = VBF. (measured optical output power/initial BOL optical output power), power measured in mW.

For example, a 50% variation of this voltage means a 50% drift of the optical output power.

[9] Total relative variation of the mean modulated optical fibre output power over the operating case temperature and supply

voltage ranges for a constant back facet voltage.

[10] A sinewave is superposed to the DC supply voltage. The device must still meet the optical and electrical specifications when

the magnitude of the sinewave measured at any VCC pin (pin 13 and 24) is up to the specified value VNM
