Transmitter Electro-Optical Characteristics
Notes:
1) Into single mode fiber, 9 m diameter.
2) Laser power is shut down if power supply is below V
3) Transmitter meets ANSI T1E1.2, SONET OC-3, and ITU-T G.957 mask patterns.

Jitter
The transceiver is specified to meet the SONET/SDH Jitter performance as outlined in
ITU-T G.958 and Telcordia GR-253.
Jitter Generation is defined as the amount of jitter that is generated by the transceiver.
The Jitter Generation specifications are referenced to the optical OC-3 signals. If no or
minimum jitter is applied to the electrical inputs of the transmitter, then Jitter Generation
can simply be defined as the amount of jitter on the Tx optical output. The SONET
specifications for Jitter Generation are 0.01 UI RMS, maximum and 0.1 UI pk-pk,
maximum. For SDH, 10 mUI RMS, maximum. Both are measured with a 12 kHz -
1.3 MHz filter in line. A UI is a Unit Interval, which is equivalent to one bit slot. At OC-3,
the bit slot is 6.4 ns, so the Jitter Generation specification translates to 64 ps RMS, max.
and 640 ps pk-pk, max.
