Datacom/Telecom Network

Optical modules are optical transceivers used for high-speed data communication and telecommunication and are used anywhere larger amounts of data needs to be sent and received. From data centers to telecom, short or long-range, optical modules are ideal for large, efficient data transfers. Optical modules can range in size and bandwidth, with the newest generation supporting up to 400GB/s telecom fiber. Although these transceivers move hıgh amounts of data, they are powerful and lightweight. 








Transmission Network 

The telecommunications networks used to transmit data using many different protocols. Today, almost all data networks are based on IP. The data in these networks are divided into separate packets and marked with destination and source addresses.

In principle, each packet can find different routes through the network and arrive at its destination at different times.

Optical modules are optical transceivers used for high-speed data transmission and are used anywhere larger amounts of data needs to be sent and received. From data centers to telecom, short or long-range, optical modules are ideal for large, efficient data transfers.

What Is Telecom Network Infrastructure?

The telecommunication network is composed of three parts: Core Network, Access Network (AN) and Customer Premises Network (CPN).

The telecom core network and access network belong to the public telecommunication network, CPN is a user-owned communication network, and traditional CPN is a single user.

One side of the access network is the core network, which is mainly composed of various business networks, and the other side is the user.

The access network serves as a link between the previous and the next and provides the services of the core network to users through the access network. The access network is a transparent transmission system that does not provide services by itself. 


Telecom Network Operation

The downstream optical module is mainly used in the three major scenarios of telecommunications backbone/carrier network, access network, data center and Ethernet.

The telecommunications backbone/carrier network and access network belong to the telecommunications operation market. Among them, wavelength division multiplexing (xWDM) optical modules are mainly used for medium and long-distance telecom core networks, and optical interconnects are mainly used for backbone networks and long-distance core networks. Capacity transmission; and the access network market is the "last mile" from operators to users, including fiber-to-the-home passive optical networks (FTTH PON, PON optical modules currently have a maximum transmission rate of 10Gbs), wireless fronthaul (5G optical modules, The current maximum transmission rate is 25Gbs) and other application scenarios.


Fundamentals Of Telecommunications And Networking

1. According to different business types and public telecommunications network methods, it can be divided into telephone communication network, telegraph communication network, data communication network, user telegraph communication network and fax communication network.

2. According to different communication ranges, it can be divided into international telecommunication networks, domestic telecommunication networks, long-distance  networks, intra-city networks and rural telecommunication networks.

3. In terms of the nature of use, there are private telecommunication networks and public telecommunication networks. The private telecommunications network is only available to certain professional users, such as the private telecommunications network of railway, military and other departments; the public telecommunications network can be used by ordinary citizens.

4. From the way of signal transmission, it can be divided into analog and digital communication networks.
