1310nm Optical laser Transmitter feature :
1. Product Summary
1310nm optical laser transmitter are important equipments to set up CATV HFC networks, and primarily used for TV video signal, digital TV signal, telephone voice signal and data (or compressed data) signal long-distance fiber transmission.The product use import high performance DFB laser transmitter as light source, RF drive adopts RF power digital automatic process technique and advanced RF pre-distortion circuit developed by our company and built-in perfect microprocessor automatic monitor system insure the excellent function of the product.
2. Function Characteristics
1. 1310NM Optical laser Transmitter use the international famous brand high performance DFB laser with narrow spectrum, good linearity and high output power.
2. RF drive adopting RF power digital automatic process technique, can according to level of input RF signal and number of channels (15-84channels), automatically processing drive level power, making the C/N, CTB and CSO always in best worth, insure product function; and be steady of output level.
3. Advance multi-frequency RF pre-distortion technique with arsenide kalium component availably improves CTB and CSO, the most important parameter of CATV, and heightens C/N at the same time.
4. Built-in perfect microprocessor automatic monitor circuit can real-time accurately monitor optical output power and temperature of the laser insure stable optical output power, and prolongs work life of the laser availably.
5. Built-in blue VFD monitor on front panel can accurately display the equipment's each work status parameter.
6. 19″1U height standard rack mount, equipped standard IEEE802.3 10Base-T Ethernet network port and RS232 network port, can expediently realizes monitor through network.
7. Support GB/T 20030-2005HFC Network control management
