TheMX-T8500AC Series 1550nm Externally Modulated Optical Transmitters are designed for analog and digital CATV QAM signals. Maxcom’s 1550nm optical amplifiers adopt world class pump lasers and American made OFS erbium-doped optical fiber components. These units provide excellent APC, ACC and ATC control, superb design in the ventilation and heat-dissipation which ensure long life and a highly reliable operation of the pump laser.
Our 1550nm externally modulated technology for the optical transmitter has no laser chirp, low dispersion distortion, and a large extinction ratio, with excellent characteristics within47~1000MHz (1200 MHz available). The External Modulator does not generate CSO distortion after reasonable bias. It can be followed by an RFOG EDFA (Multiport EDFA, such as the Maxcom MX5400 or MX5800 series) when used in large area coverage and local networks. Adopting WDM, multi-wavelength optical channels can be added and transmitted through one fiber, complimenting current developments and trends relative to triple-play, fiber to home, and xPON networks.
The Maxcom MX-T8500AC adheres to current international industry techniques and standards. The unit’s light source occupies a narrow bandwidth ( Typ = 1MHz ), low noise, continuous wave DFB laser, which is propitious to reduce the influence of dispersion. The unit’s signal modulation adopts CATV special LiNbO3 external American modulators and uses optimized control technology with independent intellectual property, thus allowing it to reach high indexes of back to back CNR ≥ 52dB, CTB ≤ -65dB, CSO≤ -65dB, SBS: 13 dBm. Lasers adopt 1548~1563nm CATV standard wavelength.
The LCD at the front panel offers equipment status and warning alarms. The laser will switch off automatically if optical power is lost, which offers security protection for the laser.
When combined with EDFA optical amplifiers, such as the MX-A5100, MX-A5400 MX-A5800 Series, the ModelMX-T8500AC allows system operators to cost-effectively transport a full slate of wideband video and data services and to distribute signals to many remote optical receiver/node locations, by utilizing the lower fiber attenuation characteristic of the 1550nm optical window. It is also designed to operate seamlessly with optical receivers and nodes from most leading manufacturers.
The MX-T8500AC is an advanced type externally modulated optical transmitter with high index, high reliability and excellent cost performance, is applicable for distribution network links in large CATV systems, head-end, hubs and OTN’s.
