Detailed Product Description

HT8520AC (CATV wavelength)
HT8520AU (ITU wavelength adjustable)

Standard type External Modulation Optical Transmitter (40~862MHz, CNR1≥53dB, SBS: 13, 16, 18dBm adj.)

This series of product has upgraded to HT8500H.

Product feature

High performance: External module technology, no laser chirp, low dispersion distortion, high extinction ratio.

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

CNR ≥ 53dB and excellent CTB, CSO index.

SBS: 13, 16, 18dBm adjustable.

ITU standard wavelength, user should adjust and enactment the laser wavelength over the front-panel with ±0.05nm stepping within range ±200GHz (±1.6nm), it suit for WDM system, network upgrade and expend the capability (HT8520AU).

AGC/MGC mode is optional at spot. OMI adjustable optimized at spot.

Consummate RS232 communication interface.

Advanced SNMP network management function.

1+1 power backup.

Machine temperature control automatically.

Excellent P/P ratio.
