1.25–2.5Gbps cost-effective transceiver based on directly phase modulated VCSEL for flexible access networks

A 1.25–2.5Gbps cost-effective transceiver based on DPSK directly phase modulated VCSEL and a heterodyne receiver with a VCSEL as LO is proposed. The proposed transmitter sensitivity is −43.5dBm for 1.25Gbps and −40.5dBm for 2.5Gbps.
