CATV External Modulation 1550nm 2*10dbm optical transmitter 50KM/100KM

    VX-EOT50XX 1550nm external modulation laser transmitter  is improved better in power consumption, output accuracy and high reliability, it is mainly used in optical fiber Transmission of Television Image Signal, Digital Signal, Television ,Telephone, Voice Signal Data (or Compressed Data) Signal.

    VX-EOT50XX 1550nm external modulation laser transmitter is a new type of high-performance 1550nm external modulation optical transmitter. The main devices adopt DFB low-noise, narrow linewidth, continuous-wave lasers with thermoelectric cooling device made in JDUS, Fujitsu, MITSUBISHI and JDUS, AVANEX CATV high linearity external modulator. 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 Huatai optimized control technology with independent intellectual property , so it can reach high index of back to back CNR ≥ 54dB, CTB ≤ -65dB, CSO ≤ -65dB, SBS: 13~18dBm adjustable . The whole unit is equipped with perfect RS232 communication interface, SNMP network management, 1+1 back-up power supply , hot-plug function available, chassis temperature auto-control.It can provide high-quality images, digital or compressed digital signal long-distance transmission for cable television and telephone communications.

    VX-EOT50XX advanced type 1550nm external 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.

Product Features

1+1 powers supply back , up hot-plug function available.

Narrow bandwidth (0.65MHz), lower noise, DFB continuous wave laser, is propitious to reduce the influence of the dispersion.

The operating bandwidth is up to 47~1080MHz.

CNR ≥ 53dB and excellent CTB, CSO index.

SBS: 13~18dBm adjustable.

ITU standard wavelength, ±200GHz (±1.6nm) adjustable.

AGC/MGC mode is optional at spot. OMI can be optimized at spot.

Perfect RS232 communication interface.

Product appication

Used in main links and distribution network links in large and middle CATV station head-end.
Analog digital hybrid transmission >200Km (with dispersion compensation).
Pure digital transmission (without dispersion compensation) >400Km,
(with dispersion compensation) >700Km.
HT8500HU ITU wavelength adjustable, applicable to the value-added service of DWDM fiber optic CATV system and CFG dispersion compensation system.
It can be used in branch FTTH that has high system index demand. Point to Point>65Km, CSO ≤ -65dB. It can provide high qualified and reliable value-added service such as RFTV, IPTV and VOD for the secondary users. It can also avoid the limitation of CSO deterioration and transmission distance caused by laser chirp for adopting 1550nm direct modulated optical transmitter.
