Customer Background
The client is a 211 key university in Qingdao, Shandong Province, with two campuses in different districts. Now, due to teaching needs, an 80g optical transmission system needs to be built between the two campuses.
Business Challenges
1. only 2 cores of optical fiber are available in the two campuses, and the link length is about 70km. Due to serious aging, the optical fiber loss is very large;
2. there are many types of interconnected services, including voice, video, intranet, etc., which need to be physically isolated;
3. the switches on both sides of the customer side belong to different brands. Xianyitong also needs to be compatible with different brands of equipment on both sides of the customer side.
Solution
1. xyt-16416 active wavelength division solution is adopted, and different converters are configured to convert voice and video signals into digital optical signals for wavelength division multiplexing transmission;
2. a total of 16 wavelength division service channels are configured, with single channel transmission of 10G. 8 channels are configured to meet the customer's 80g transmission. Different services enter different wavelength division service channels, and the physical isolation between services has been achieved;
3. at the same time, one network management channel is also configured to interconnect the network management of the two devices, so as to realize remote management of the end-to-end devices;
4. optical fiber amplifiers are configured at both the transmitting and receiving ends to solve the problem of excessive optical attenuation and allow the system to have sufficient redundancy;
5. adopt different compatibility codes according to the user's switch to improve the compatibility performance.
Value Embodiment
1. from demand discussion, equipment selection, scheme determination, and after-sales on-site installation and commissioning, xianyitong provides perfect one-stop services;
2. the solution of xianyitong not only meets the existing needs of customers, but also meets the capacity expansion needs of customers in the next few years, exceeding customer expectations;
3. after the system started to operate, the optical cable was cut several times in the middle of the process, resulting in the increasing loss of optical fiber. The technical engineers of xianyitong actively cooperated with customers to solve problems;
