The Study of High-Speed OC-48 Optical Transceiver Modules
In this thesis, the fabrication and performance of the OC-48 optical transceiver modules applied in optical communication network are studied. The optical transceiver modules consist of two parts¡Gthe transmitter and receiver. In the transmitter, laser driver IC and 1310nm FP (Fabry-Perot) Laser are used. In the receiver, limiting amplifier IC and 1310nm ROSA (Receiver Optical Sub-Assembly) are introduced.
The static response of L-I curve and dynamic responses of VNA (Vector Network Analyzer) are studied. The effective bandwidth of LD can be observed from dynamic response. These parameters can help us to determine the LD driver for use in high frequency operation. Then, the method of DC-Coupling circuit to drive IC can be successfully transferred to optical signal.
The operation conditions of an OC-48 transceiver module are the laser output power of -6dBm, signal pattern of 27-1, and data rate of 2.5Gb/s. The result of eye diagram measurement can meet the mask of ITU-T standards with the deterministic jitter of 49.88ps (0.1247 UI).¡CAfter 1 meter fiber transmission, the receiver can meet ITU-T standard with deterministic jitter of 125.28ps (0.3132 UI). In the future, the receiver should be improved to get a lower deterministic jitter.
