1 2015 1 SEI 186 65 100 Gbit/s 2 25 Gbit/s 1 IC IC LC TOSA 25 Gbit/s For a 100 Gbit/s optical transceiver that satisfies the demand of high speed transmission, the authors have developed two types of 25 Gbit/s optical transmitter modules so that a user can select a module depending on transceiver architectonics. One of the two modules has an in-house driver IC for Electro-absorption (EA) modulator integrated in a laser chip, and the other has no driver IC. These transmitter modules are transmitter optical sub-assembly (TOSA) type devices with flexible printed circuit (FPC) and LC receptacle.

2 The evaluation results showed good modulation characteristics, lower power consumption and long-term reliability. This paper describes the outline of 25 Gbit/s optical transmitter module structure and evaluation results.
