TET-1500 series is a model of CATV 1550nm External Modulation Optical Transmitter according with current international industry technique standard. The whole unit light source adopts narrow line width（Typ.=0.65MHz), low noise and continuous wave DFB laser, which is propitious to reduce the influence of dispersion. Adopting LiNbO3 external modulator, TET-1500 externally modulated optic transmitter can reach high index of CNR≥53dB,47~860 or 47~1080MHz,CTB≤-65dB, CSO≤-65dB,SBS:13～19dBm adjustable,50 km transmission. The whole unit is equipped with SNMP network management, 1+1 plug-in back-up power supply and casing temperature auto-control.

TET-1500 can transmit whole band CATV signal. Ensuring excellent signal when at low frequency, it is applicable for main links and distribution network links in large and middle CATV station head-end.

Features

Ø  High performance: Micro-wave Source Technology, adopting RF pre-distortion technology, system get perfect CTB,CSO and SBS index when CNR≥53dB.

Ø  Flexibility: The phase modulation Technology of the modulator boost the input optical power to the utmost, thus reaching long-distance transmission by ensuring excellent system CSO,SBS 13~19dBm adjustable, AGC/MGC mode is optional at spot, OMI can be optimized at spot. Suitable for various network.

Ø  Reliability: 19"1U standard rack, 1+1 plug-in back-up power supply, which can work at 86~265voltage, MS switch automatically, casing temperature auto-control.

Ø  Monitor the working state of modulator and laser. Working parameter shows on the LCD panel. 

Ø  SNMP network management

Ø  EMC、LVD and CE approved.
