4.Applications
The CATV RF signal is modulated into 1550 segments (1535~1565nm) optical signals through an external modulation transmitter or an direct modulation optical transmitter, amplified by EDFA or EYDFA, and though the optical distribution frame(ODF) to user receipt. The optical receiving power is generally designed from -12 to -9dBm, and apply the HSGS10076 optical receiver with RF76dBuv±1output.
