Máy Phát Quang 1550nm FWTA-1550ST
With the development of CATV fiber network for many years, CATV signal, from the earliest pure one-way transmission to present two-way interaction, gradually moves on to be integration of three networks, and achieves it through Ethernet passive accessing method of EPON, GPON.
In all optical 1550nm system, how to interrupt local personalized programs and value-added services becomes a problem of network operators.
FWTA-1550ST series 1550nm_RF insert direct modulated optical transmitter are produced under such circumstance. It build-in high quality 1550nm inner debug optical transmitter.
After reasonable power budget, multiplex the inter-cut signal to the main optical line.
The optical amplifier unit adopts low-input design that ensures good CNR of the main optical line when the input range is +10dBm~0dBm.
Meantime, in order to avoid the optical signal interruption in the main circuit, there have a wave adjustment set inside of it.
