Finisar’s DM80-02 transmitter optical sub-assembly (TOSA) employs proprietary Chirp
Managed Laser (CML
TM
) 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 C-band and L-band for DWDM versions. Also included in this TOSA
package are 2 photo-detectors for power control and wavelength locking, together with 2
TECs for temperature stabilization. The miniature size of this TOSA ensures it suitable
for integration into XFP, X2, Xenpak and other transceiver modules. Key specifications
for the optical and electrical characteristics, physical requirements, environmental
conditions and reliability/quality requirements are detailed in this document.
