  • Simultaneous demultiplexing and clock recovery of high-speed OTDM signals using a tandem electro-absorption modulator
    Publication number: 20030043431
    Abstract: Simultaneous demultiplexing and clock recovery of high-speed (e.g., 80 Gbps or 160 Gbps) optical time division multiplexing (OTDM) signals is achieved using a tandem electro-absorption modulator (TEAM). The TEAM has a monolithically integrated SOA to compensate the insertion loss and two EAMs to reduce the switching window. The demultiplexing and clock recovery may be performed by a single TEAM, or by two or more TEAMs. A fiber Raman amplifier may be used to boost the intensity of the OTDM signals during transmission.
