Sintai Communication Co.,LTD

A dedicated line service processing board-P222&P422 OTU Board
The transmission requirements for optical transmission dedicated line services mainly revolve around core indicators such as bandwidth, latency, reliability, security and stability. Besides commercial high-capacity dedicated lines, we have also launched small-capacity dedicated line service processing boards--P222 &P422 OTU board.

1. Support hot-swappable and FE~OTU2e service type
2. Support line-side online delay measurement at the ODU layer
3. Support Latency Measurement & Port Loopback
4. On-board 1+1 protection
5. Alarm and Performance Monitoring

Under the demand for high-speed and large-capacity services, the demand for low-rate dedicated line services is not widely utilized. However, dedicated line services, as a common requirement, cannot be ignored. This type of board precisely meets the security of the physical layer, exclusively utilizes the optical path, supports E2E QoS strategies, and uses OTDR cable detection to control the annual failure rate of the optical fiber link. It is the optimal choice for low-rate dedicated line services.

What exactly are the“muxponder”and“transponder”commonly mentioned in WDM systems, and how do they differ?

This is the most crucial component in the electrical layer - the optical Optical Transponder Unit (abbreviated as OTU board). It can convert the client services into standard wavelength optical signals that meet the requirements of the WDM system through operations such as mapping, multiplexing, and convergence.

Transponder
N in to N out: N * low-speed client-side services to N * optical signals with standard wavelengths

Muxponder
N in to 1 out: N x low-speed client-side services to one high-speed optical signal with standard wavetolengths

So far, Sintai has launched OTU boards that can support transmission ranging from 10G to 800G for WDM systems. With the rapid update and iteration of the network, it is expected that in the future, there will be more capacity-level electrical layer boards released, which can support various granularity of services for accessing WDM systems. https://www.optical-sintai.com/

In the previous episode, we discussed the issue of TE link shortage. So how to solve it?
Besides the currently most popular AI algorithms, are there any more cost-effective and faster solutions? Sintai Communication Company has launched the following several new-generation solutions.
1.Upgrades to Next-Generation Optical Transmission Technology--High-speed coherent optical module
Deploying higher-capacity interfaces, such as 800G/1.6T, on optical transmission equipment enhances per-fiber transmission capability (through C+L band expansion), significantly increasing transmission capacity and efficiency. This reduces fiber consumption and excessive fiber connections, shortening construction time and complexity, thereby lowering certain labor costs.
2.Deep Integration of IP + Optical --Open line system
It can support virtually any application in their networks, achieve “pay as you grow ”economic benefits, seamlessly support multiple generations of embedded and pluggable optics, and deliver solutions with the lowest cost and power per bit along with maximum flexibility.

💟 Happy International Women's Day!
Sintai Communication Company pays tribute to all ordinary yet great women. May you hear countless voices, but remain true to yourself.hashtag

What is the relationship between the optical layer and the electrical layer in the WDM system, and what is a TE link?

Optical-layer links correspond to fibers, and electrical-layer links correspond to electrical-layer channels, which are used to transmit data.
TE link is a logical concept. Optical and electrical links are the basis of TE links. TE links are abstract of optical and electrical links.

Nowadays, with the rapid development of the network, there is a problem of tight TE link traffic in the transmission network. How have we solved this issue?
