Production Description
?
?????? CNOT1550 that accords with current international industry technique standard is a 1550nm Externally Modulated Optical Transmitter. The whole unit light source adopts narrow bandwidth (0.65MHz), low noise, continuous wave DFB laser, which is propitious to reduce the influence of dispersion. The whole unit signal modulation adopts CATV special LiNbO3 external modulator of American company and optimized control technology with independent intellectual property , so it can reach high index of back to back CNR≥53dB, CTB≤-65dB, CSO≤-65dB, SBS: 13~18dBm adjustable.
?????? CNOT1550, advanced type externally modulated optical transmitter with it's high index, high reliability and excellent cost performance, is applicable for main links and distribution network links in large and middle CATV station head-end.
?????? Laser adopts ITU standard wavelength, wavelength adjustable, dual fiber output. Through the LCD menu in the front-panel, users can adjust and set the wavelength within the range of ±200GHz (±1.6nm) by pushing the button with ±0.05nm stepping.
