8.AGC/MGC mode is optional at spot. OMIcan be optimized at spot.
9.Perfect RS232 communication interface.
10.Advanced SNMP network managementfunction.
11.Casing temperature auto-control.
12.Excellent Price-Performance.
CATV 1550nm Optical Transmitter Application
1. Used in main links and distribution network links in large and middle CATVstation head-end.
2. ITUwavelength adjustable, applicable to the value-added service of DWDM fiberoptic CATV system and CFG dispersion compensation system.
3. It can beused in branch FTTH that has high system index demand
