Advantages with pluggable optics

Low development cost Bulk of work on module vendor ROI for module vendor from several system vendors

Highly flexible solution One board can be used with different pluggables optics;

Short/long reach, CWDM/DWDM, high/low data rate… One plug can be used in several different boards

Second source of transceivers Continuous price pressure Risk management; if one vendor fails there are options

Low cost of inventory, easy procurement Source optics and boards independantly Allows wavelength planning at later stage

Based on the SFP format MSA compliant Fabry-Perot transmitter APD receiver optimized for injection-locked signal

What’s different from a standard SFP? Transmitter designed for DWDM injection locking

=> Automatic tuning to the right wavelength, determined by filter port Seeding signal
