10Gb/s 120km Telecom CML 13pin-GPO Butterfly Transmitter

Finisar’s DM80-01 butterfly transmitter module employs proprietary Chirp Managed

Laser (CMLTM) technology and has been specifically designed to transmit 10Gb/s data

over physical distances up to 120km. The module is comprised of a directly-modulated

DFB laser chip and a co-packaged proprietary optical spectrum reshaper (OSR) passive

optical element. The OSR component also provides a frequency locking function and

allows operation on the ITU-T channels within ±2.5GHz with coverage across both Cband

and L-band for DWDM versions. Also included in the standard butterfly footprint

are 2 photo-detectors for power control and wavelength locking, together with 2 TECs for

temperature stabilization. Key specifications for the optical and electrical characteristics,

physical requirements, environmental conditions and reliability/quality requirements are

detailed in this document.
