External Modulation Series RF Optical Transmitter
—— YUK1000-T-1550 Series ——
Overview
YUK1000-T-1550 external modulation series optical transmitter is a first choice product for broadband transmission system and large-capacity CATV optical transmission system networking. It is mainly used in optical modulation, optical insertion, WDM and related network upgrades and expansions of large-scale 1550nm optical transmission systems. It is the core equipment for realizing triple network integration, FTTX, and 1550nm optical wave RFTV broadcast network systems.
Product Features
l Segmented specifications can meet the requirements of different networks. There are single-channel output and dual-channel output. The output optical power ranges from 3dBm to 10dBm, providing users with great selectivity.
l Use a narrow linewidth, low-noise imported DFB laser as the light source, and a highly linear LiNbO3 external modulator as the external signal modulator.
l The superior pre-distortion circuit still has perfect CTB and CSO performance values when reaching high standard CNR values.
l Automatic gain (AGC) control enables stable signal output under different RF input levels.
l Built-in dual power supplies, automatic switching, and hot-swappable support.
l Fully automatic chassis temperature control and intelligent fan will only start running when the chassis temperature reaches 32°C.
l LED display, with multiple functions such as laser monitoring, digital display, fault alarm, network management, etc. Once the working parameters of the laser deviate from the allowable range set by the software, an alarm will be prompted.
l Standard RJ45 interface, supports SNMP, is used for remote network management of computers and adjustment of AGC, SBS, OMI, etc.
l Through the RS-232 standard interface, users can change the model and specifications displayed on the panel, and can also be used for local network management and monitoring of computers.
