1.3μM MINI-DIL DFB LD MODULE FOR 2.3GBPS OPTICAL TRANSMISSION

摘要

NEC has developed 1.3μm impedance matched 2.5Gbps mini-DIL MQW-DFB LD modules that could be mount on a board easily. Optimization of optical coupling can realize better coupling efficiency and minimize the optical isolator. Also separating a DC line and a signal line and building in a impedance matched circuit, improve a small signal response has been improved. Stable 2.5Gbps-50km transmission can be performed without temperature control at 0 to 70 deg C operation.
