ER8602JLE Fiber Optic CATV FTTB Optical Node
Description :
ER8602JLE Optical receiver is our new high quality 2 output ports products that especially used in CATV network.
The preamp adopts GaAs MMIC amplify module and the postamp adopts GaAs module amplifier.With optimization design and plentiful technical experience that made this equipment with high performance specification. Debugging of project is easy because of MCU-Controlled display.It is a ideal model for CATV network.
Performance Characteristics
n High responsible, with PIN photoelectric converter.
n 1000MHz bandwidth design
n Optimization and typical circuit design, the pre adopts SMT process and the post adopts module amplify that made the photoelectronic signal transmission fluency.
n Professional RF attenuation chip whose attenuation and equalization has good linearity, high precision.
n GaAs amplifier parts,power doubler output, high gain and low distortion.
n Overall machine is controlled by Single Chip Micyoco,and digital display is adopted to show parameters.So it is easy to operate, and performance is stable.
n With AGC, when the input optical power range is -7~+2dBm, the output lever, CTB and CSO are keep constantly.
n Class II network management transponders can be connected to it.
