Transmitter Section

 

Transmitter is designed for single mode fiber and operates at a nominal wavelength of 1310nm or 1550nm . The transmitter module uses a FP laser diode and full IEC825 and CDRH class 1 eye safety. The output power can be disabled via the single TX-disable pin.
 
Logic LVTTL HIGH level disables the transmitter. It contains APC function, temperature compensation circuit, PECL data inputs, LVTTL TX-disable input and TX-fault Output interface.

Receiver Section
 

The receiver section uses a hermetic packaged front end receiver ( InGaAs PIN and preamplifier). The post amplifier is AC coupled to preamplifier through a capacitor and a low pass filter. The capacitor and LPF are enough to pass the signal from 100Mb/s to 200Mb/s without significant distortion or performance penalty. The LPF limits the preamplifier bandwidth to improve receiver sensitivity. As the input optical is decreased, LOS will switch from low to high. As the input optical power is increased from very low levels, LOS will switch back from high to low.

 

 

DDMI Section

The DDMI contains an EEPROM. It provides access to sophisticated identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information.
