The output optical power is 0-3dB, which you can manually adjust according to your needs. The wavelength range is 1528 ~ 1563nm. lated laser (EML) is an integrated device of EAM and DFB laser. With the advantages of performance, cost and volume, the application field has been gradually extended to CATV optical transmission system in recent years, which is used to replace direct modulation optical transmitter and exter ing. The Prisma II optical network is an advanced transmission system designed to optimize network architectures and increase reliability, scalability, and cost-effectiveness. LCD displays working parameters in real time, it supports sound and light alarm. The Maxcom MX-T1500A is a 1550nm direct modulation optical transmitter with high index and AGC function. Maxcom incorporates a high linearity and a low chirp DFB laser, built-in pre-distortion compensation and AGC, APC, ATC closed loop control, which improve the performance index. Designed for long distance transmission and local network coverage, it is widely used in optical modulation, optical insertion, wavelength-division multiplexing (WDM), as. According to the Next Generation Broadcasting (NGB) planning and PON standards, 1550nm is defined as the transmission wavelength for HFC downstream.
