[CATV]DGW-TX0862 Series



DGW-TX0862 Series

1550nm External Modulation Optical Transmitter 개요 디지윌 DGW 3542는 Video/Audio 신호를 MPEG2/H.264 SD/HD로 encoding후 ATSC로 modulation하는 제품입니다. Encoding module(HDMI/HD-SDI)이 카드형식으로 구성되어 있어 필요에 따라 맞는 카드로 쉽게 바꾸어 사용할 수 있는 구조입니다. 또한 고객의 다양한 요구를 충족하기 위해 1xASI input, 2xASI output, 1xUDP IP port를 제공합니다. 주요특징

High performance: Externally modulated technology, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~862MHz.

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.

Advanced SNMP network management function.1U (19” stander), 1+1 power supply backup, switch automatically

1U, offering status appearance and diagnosing fault with LCD, standard RS232 communication interface, SNMP network management function

Excellent P/P ratio in area
