neral Description 
GGE-20FT-1310, GGE-20FT-1550
GGE-20FT series optical transmitter, adopt high linearity DFB laser, modulated directly, It can transmit 45-2600MHz digital TV.
Optical operating wavelength is optical as 1310nm or 1550nm. 1550nm optical transmitter, ITU standard wavelength can be selected, suitable for DWDM to realize network-upgrading and capability-expansion. Meanwhile, add EDFA can amplify the optical power, compatible with any FTTx PON technology.
Performance Characteristics
l Smart digital display & control monitor system, simplified operation.
l Combined RF in port or separate CATV/SAT IF RF in port can be customized.
l High band wide 47-2600MHz.
l Suitable for digital TV and satellite TV application.
l 1310nm/1550nm optical output power from 2~10mW optional.
l 1550nm Tx can be amplified by EDFA, YEDFA to cover large scaled FTTH.
l Alumininum casing, good heat dissipation and performance.
l Compatible with any FTTx Pon technplogy.
