Absolute Maximum Ratings
Stress below listed absolute maximum rating may cause permanent damage to the module. This is a stress only and functional operation of the module is not implied at these or any other conditions in excess of those given in the operational sections of this data sheet. Exposure to Absolute Maximum Rating for extended periods may affect module reliability.

note 3 : Tolerable broadband noise on the power rail is under 50mVpp with frequency range of 50Hz to 1MHz. note 4 : Internally, AC coupled with 50 termination. note 5 : If transmitter is used at more than 1.25Gb/s bit rate, Clocked-mode must be selected. note 6 : Back face voltage is measured with a GND reference and normalized at the beginning of life relative to the initial optical output power. For example, a 50% drift in output power correlates to a 50% variation on the detected back face voltage.

1) : The falling edge of CKI+ clock input signal is at the DI+ data eye pattern crossing point. 2) : When open (or low) the module operates in Clocked-mode. When high the module operates in Non-clocked-mode. 3) : When open (or low) the module is in the operating mode. When high the module is in the shut down mode (no optical output power). 4) : TEC_GND must be connected with GND. 5) : When provided a digital alarm indicates that the laser is degraded. The active level is a low level. 6) : Alarm indicating when the laser temperature exceeds the threshold level. The active level is a high level. 7) : BACK(+), LDA and TDA pin cannot drive capacitive load. Acceptable capacitance is less than 50pF. 8) : When open (or low) the module outputs wavelength 1. When high the module outputs wavelength 2. (See wavelength table.)
