HT1500-C
Catcast
Applications
HT1500 series external modulation optical transmitter is one of the independent 1550nm laser transmission equipment productions of CATCAST, which has a complete independent intellectual property. It has high performance, high reliability and excellent performance and price ratio. It can be widely used in all kinds of medium and long distance digital and analog signal communication. The application scene includes large and medium-sized cable TV. Trunk and distribution network, CWDM/DWDM system, optical fiber sensing and security monitoring system. According to the requirements of application scenarios for device, this series of products contains 3 different configurations:
The HT1500-A series focuses on product cost and is an economical external modulation transmitter. The JDSU single fiber modulator is used to satisfy the users’ needs of point to point transmission, and the SBS value can be controlled in 13-16dBm, (analog signal transmission <50km, digital signal <75km). It can be cascaded for long range amplification to meet the signal transmission needs between the two stage machine room and the distribution network. It is an ideal choice for the 1550nm trunk transmission network.
The HT1500-B series uses OCLARO dual fiber modulator, SBS value can be controlled in 13-19dBm, can be used for point to point long distance transmission, and can also be used to distribute network signal (with high SBS threshold, the device can still maintain good signal quality when the maximum 19dBm laser power is pushed to the fiber transmission network). It is a widely adopted optical transmitters.
The HT1500-C series uses wavelength adjustable laser module, JDSU dual fiber modulator, and SBS threshold 13-19dBm. It is suitable for signal front machine room and middle distance trunk link simulation, digital signal broadcasting and optical interpolation. It is the best choice for constructing large and medium HFC and complex analog and digital signal interaction network.
