HOTLINE : 0988 49 1900

 OPTICAL TRANSMITTER 1550NM VTS HT-8500HC

• 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 wavelaser, 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.
• 1+1 power supply backup, switch automatically.
• Casing temperature auto-control.
• Excellent P/P ratio.
