This OTN is what we call optical transmission network, and many people are confused about it. It is a very important area, mainly to carry out various processing and transmission related processing of optical signals. The optical signal is processed and transmitted through a series of complex means to ensure that the communication can be carried out stably and reliably!
Detailed explanation of the important role module of OTN
1. The first thing is to reuse the functional module, and we need to talk about it carefully. There are various optical signals, different specifications, and different traffic, such as our telecommunications network, radio and television signal network. Through multiplexing technology, these different signals can be cleverly mixed together and sent out in an optical fiber! This can greatly save resources and reduce expenses. We can also say that reducing expenses is of great significance, and this is the momentum. For example, through multiplexing technology, we can lay several less fiber optic lines.
2. Cross-connect modules are also particularly important. It is very useful in optical path conversion and path adjustment. The signal is not always on the same route, right? There is inevitably a problem that requires flexibly adjusting the direction of the signal. Just like urban transportation, it means reasonable planning and guidance. For example, in some emergency accidents, or when business traffic changes significantly at different times, this cross-connection function will be effective! The optical signal can be flexibly directed and adjusted according to the needs, so as to ensure that the entire transmission system is working stably and stably.
3. There is also a protection switch function, which should not be underestimated. This mainly ensures that when certain sudden failures occur in the network, the signal can still be transmitted intact. Take protection or quick switching measures. For example, if any optical fiber line is broken, it will be broken. In this emergency situation, other normal working lines will immediately begin to play the main role of the faulty line. In this way, the communication service will not be disconnected. Service interruption is definitely a serious matter. This function can ensure the network's "resilience" well.
contrast
Traditional network transmission, such as PDH networks in the past, played a very important role, but they are always not very good at meeting the current rapid growth of large amounts of data. In terms of capacity and flexibility, all defects are exposed. Compared with OTN, it is better to be stronger and more flexible. If the signal processing is more in place, the transmission will appear more stable, so it will be more flexible to deal with more problems. Moreover, some traditional ones have to be equipped with different equipment separately, so OTN is highly integrated with some related functions! This is definitely a big benefit.
OTN Q&A
Q: Do you need to pay special attention to key points during the OTN networking process?
Answer: Oh, the key point is the sea! There are many, many here. For example, the distribution of sites and the path of exposure should be carefully planned and not mess around. Try to ensure that the distance between optical equipment is appropriate and has little impact on light decay? Secondly, pay attention to the gain and loss of the optical plate on the supporting panel, and match it reasonably. If it is not done properly, the packet may be lost, and the signal attenuation will increase. Finally, there is another thing that gateway nodes must ensure sufficient security. These gateway functions must be done well and in place. Let’s focus on a few key points!
Q: Why do you say OTN is more scalable?
In the initial stage, network construction will generally be planned for later upgrades and expansions. If it is a traditional network, its processing architecture will be too stubborn. It is very difficult to operate if it grows larger. . OTN has a very free and flexible architecture. If you add a new business node in the future, you will need to add some of it. You just need to operate appropriately in the existing framework. Add necessary lines and adjust configurations. The entire operation does not involve a large number of changes, such as earth-shaking changes, and will not cause any damage to the bones, so the expansion is much more powerful than these. .
In my opinion, under the current trend of big data and 5G requirements, OTN, as an important facility to ensure stable and fast communication lines, will definitely have broad prospects! Our field must follow us anytime and at any time, continuously improve our technical level, respond to new changes and changes, make our communication network better and have a better experience in use, so just move in this direction. Then, I heard that there is a platform that is not bad and provides global procurement services for weak current intelligent products! Give many relevant practitioners a lot of help in the whole process
