Manufactory Wholesale 1550nm External Optic Transmitter 2
Outputs for CATV Networks with WDM Technology
Looking for a reliable solution for large-scale CATV network coverage? The 1550nm External Optic Transmitter 2 Outputs delivers exceptional performance with no laser chirp, low dispersion distortion, and a large extinction ratio, ensuring high-quality signal transmission within 40~862MHz. Ideal for main and distribution links in CATV headends, it supports WDM technology for multi-wavelength transmission over a single fiber. With output power up to 10dBm and a CNR of ≥53.0dB, this transmitter is perfect for triple-play and fiber-to-home applications.

1550nm External Optic Transmitter 2 outputs is the core equipment in the RFTV network system.
1550nm External Optic Transmitter 2 outputs
1550nmExternal OpticTransmitter 2 outputs has nolaser chirp, low dispersion distortion, and large extinction ratio, with excellent characteristic within 40~862MHz. External Modulator doesn't generate CSO distortion after reasonable bias. It can be followed by amplifier when used in large area coverage of over-long trunk and local networks. Adopting WDM, multi-wavelength optical channels can be transmitted through one fiber. 1550nm optical fiber CATV follows the current development trend of triple-play and fiber to home.
1550nm External Optic Transmitter 2 outputs with it's high index, high reliability and excellent cost performance, is applicable for main links and distribution network links in large and middle CATV station head-end.
