Application
Tunable Laser
Specifications and application
AEPONYX’s tunable lasers and wavelength multiplexing can be used to expand network capacity while re-using existing fiber infrastructure and find commercial applications for NG-PON2 transceivers (with C-PON transceivers on the product roadmap).
AEPONYX introduced a T-DBR EML laser with semiconductor optical amplifier (SOA) that is burst-mode transmission capable of supporting 10G NRZ and soon, 25G NRZ and 50G PAM4.
Fast tuning time, extended reach, high output power, integrated shutter, and low spectral excursion are some of the performance benefits achieved. In addition, AEPONYX has the ability to manufacture and test these products in high volume in order to keep the per-unit costs low and scale for high-volume markets.
