In the cable television network, the application of fiber optic products widely covers signal transmission, amplification, distribution, and terminal access, that is, the entire process of “backbone distribution terminal”.
Yingda has been focusing on fiber optic communication for 15 years and has a good understanding and long-term supply experience in the practical application and market demand of IPTV. All products can help customers solve problems and have received unanimous praise.
Yingda independently produce and develop various fiber optic transmission, fiber optic connection, fiber optic testing, and other products required for cable TV networks. All products are telecom standard, and 100% qualified test before delivery.
FTTR (Fiber to the Room) refers to an all-optical networking solution that extends fiber optic cables to every room in a home, replacing traditional Ethernet transmission methods. This design upgrade from Fiber to the Home (FTTH) to Fiber to the Room (FTTR) ensures seamless coverage of signals throughout the entire house.
In the cable television network, the short distance distribution should be selected as the fusion tapered type (FBT splitter), and the long distance high-density distribution should be selected as the planar waveguide type (PLC splitter). The total attenuation throughout the entire process should be controlled within -15~-20dBm (the optimal range for optical receivers).
EYDFA single input multiple output, no relay transmission distance can sing 50-100%, high power can support more channels, reduce the cost of waiting for a unit channel, can reduce the number of amplifiers and fiber occupation, and the overall cost can be reduced by more than 30%. It also reduces node failure rate and positioning more accurately. But it has a higher unit price and is more flexible for cost sensitive or short distance low-power scenarios EDFA.
The attenuation of optical links requires comprehensive calculation of fiber optic transmission, splitter distribution, and connection point losses. For specific operations, please refer to: How to calculate the attenuation of fiber links in a Cable TV network?
We can quickly identify the cause of excessive attenuation through the following pricing steps: clean the fiber optic connector, check the bending status of the fiber optic cable, turn off the optical modem and restart for basic testing. If the problem is not found, continue to use OTDR and optical power precise positioning and full range optical power testing. For specific methods, please refer to: What should do if the attenuation of fiber link is too large?
High productivity efficiency, skilled front-line operators and strict production control ensure timely delivery.
High-precision testing equipment and top industry quality control system ensure high quality standards.
Long-term stable supply chain and cost control that changes in line with market trends ensure the best price
