Product Description
HT8500H
HT8500HC (CATV wavelength)
HT8500HU (ITU wavelength adjustable)
Advanced type Externally Modulated 1550nnm CATV Optical Transmitter

(47~862MHz, CNR1≥ 53dB, SBS: 13~18dBm adj. )

Product description

Huatai HT8500H, advanced type externally modulated 1550nm catv 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. High performance: Externally modulated technology, no laser chirp, low dispersion Distortion, high extinction ratio, with excellent characteristic within 40~862MHz.
2.1+1 powers supply back, up hot-plug function available.
3. Narrow bandwidth (0.65MHz), lower noise, DFB continuous wave laser, is propitious to Reduce the influence of the dispersion.
4. The operating bandwidth is up to 47~1080MHz.
5. CNR ≥ 53dB and excellent CTB, CSO index.
6. SBS: 13~18dBm adjustable.
7. ITU standard wavelength, ± 200GHz (± 1.6nm) adjustable.
AGC/MGC mode is optional at spot. OMI can be optimized at spot.
8. Perfect RS232 communication interface.
9. Advanced SNMP network management function.
10. Casing temperature auto-control.
11. Excellent P/P ratio.

Main application

1. Used in main links and distribution network links in large and middle CATV station
Head-end.
2. HT8500HU ITU wavelength adjustable, applicable to the value-added service of DWDM
Fiber optic CATV system and CFG dispersion compensation system.
3. 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.
