1550 Optical Transmitter

                               1550 Optical Transmitter

 

Product Display

1550 optical transmitter-1550nm external modulated optical transmitter which is the highest level product. Adopt Narrow line width(Typ.=0.3MHz) and Low-noise imported DFB laser as the source; 

Adopt high linear LiNbO3 external modulator as RF signal modulator, with special CTB,CSO, dual high frequency SBS threshold control etc. core technologies; designed for long-distance transmission networks.

Features

•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 47~862MHz (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 the spot. OMI can be optimized at the 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.

Aplications

1. CATV head-end. 

2. FTTH, FTTx PON, RFOG etc. 

3. IPQAM etc. narrow insertion data service. 

4. Improve the flexibility and convertibility of network wavelength. 

5. Make full use of existing optical fiber resources to achieve network upgrade and capacity expansion. 

6. DWDM system,CATV super-capacity backbone and Metropolitan area network.
