The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the DFB laser and the APD photo-detector. The module data link up to 160 km in 9/125 µm single mode fiber. The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system can also disable the module via I2C. Tx Fault is provided to indicate degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access. Product Specifications I.

Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V. 3. Should be pulled up with 4.7k-10k ohms on host board to a voltage between 2.0V and 3.6V. MOD_DEF(0) pulls line low to indicate module is plugged in. 4. This is an optional input used to control the receiver bandwidth for compatibility with multiple data rates (most likely Fiber Channel 1x and 2x Rates). If implemented, the input will be internally pulled down with >30kΩ resistor. The input states are: 1) Low (0–0.8V): Reduced Bandwidth 2) (>0.8, <2.0V): Undefined 3) High (2.0–3.465V): Full Bandwidth 4) Open: Reduced Bandwidth 5. LOS is open collector output should be pulled up with 4.7k-10k ohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. IV.
