Manufactory Wholesale 1550nm External Fiber Optic
Transmitter for RFTV Network Systems with EPON GEPON P2P
Access
Looking for a reliable solution for high-performance RFTV network systems? The 1550nm External Fiber Optic Transmitter is the core equipment designed for unidirectional analog and digital video broadcasting. Featuring externally modulated technology, it ensures low dispersion distortion, high extinction ratio, and operates within a bandwidth of 47~862MHz. With CNR ≥ 53dB, adjustable SBS (13~18dBm), and ITU standard wavelength (±1.6nm), it’s ideal for EPON, GEPON, and P2P access modes, enabling triple-play and FTTx applications.

1550nm External Fiber Optic Transmitter
1550nmExternal Fiber Optic Transmitter is the core equipment in the RFTV network system. RFTV is a unidirectional analogue and digital video broadcast. It adopts high efficiency modulation mode for RF carrier wave and its economy, flexibility and bandwidth validity is beyond comparison of IPTV. By adopting EPON, GEPON or P2P access mode to realize triple-play and FTTx, RFTV broadcasting network in 1550nm optical wavelength still plays an important role.
