Channel, SONET OC-12 and OC-3. Supports FEC at 2.67Gb/s.
2. Tested with a PRBS 231-1 test pattern interspersed with 72 consecutive ones and 72 consecutive zeros
unless otherwise specified.
3. Attenuation of 0.275 dB/km is used for the link length calculations (per GR-253 CORE). A 2dB
penalty is included for dispersion on >2Gb/s data rates. Distances are indicative only. Please refer to
the Optical Specifications in Table IV to calculate a more accurate link budget based on specific
conditions in your application.

Notes:
1. Pins 19 and 20 provide an analog voltage output proportional to the monitor photodiode current,
per the following formula: IBIAS = .V(Pmon+ - Pmon-) / 200Ω. The figure below shows the
equivalent circuit.
2. Pins 17 and 18 provide an analog voltage output proportional to the laser bias current, per the
following formula: IBIAS = .V(Bmon+ - Bmon-) / 10Ω. The figure below shows the equivalent
circuit.
3. Pin 1 is used to monitor the received photocurrent. It must be connected to a positive voltage
within the range specified above. The current that flows into this pin is the received photocurrent.
The received power is given by the photocurrent multiplied by the photodiode responsivity.
