The rest of the downstream optical signal is re-modulated by an intensity modulation technique of 10-Gbps RZ-OOK. The generated upstream signal is transmitted back to the CO using SSMF through a complete path.
In the downstream, the 10-Gbps RZ-DPSK data signal provides a BER of [10.sup.-9] at received power of -37 dBm, while in the upstream, the 10-Gbps RZ-OOK data signal provides a BER of [10.sup.-9] at a received power of -25 dBm.
The downstream data signal is re-modulated using RZ-OOK for upstream data signal.
