What is OTN transmission?

OTN Transmission (Optical Transport Network) is a network standard developed to improve the bandwidth utilization of optical networks, simplify network management, and improve network reliability and flexibility. Its core idea is to realize the transmission, management and monitoring of optical signals through digital means.

The following are some of the key features and components of OTN transport:

1. Digital Encapsulation: OTN uses digital signal encapsulation technology to encapsulate customer data flows (for example, Ethernet, SDH/SONET, Fiber Channel, etc.) into a standardized OTN frame structure.

2. ODU (Optical Channel Data Unit) and OTU (Optical Channel Transmission Unit): This is the frame structure defined in the OTN standard to accommodate different customer data flows.

3. Forward Error Correction (FEC): OTN provides FEC capabilities for optical signals. This is an error correction coding technology that can enhance the transmission distance and flexibility of optical signals.

4. Full Transparent Transmission: OTN can transparently transmit various customer data flows without the need to interpret or process the data content.

5.Enhanced management and monitoring: Compared with traditional optical networks, OTN provides more powerful performance monitoring and management functions, including monitoring of signal quality, fault location, network topology and other key parameters.

6. Multi-layer protection: OTN supports multiple protection and recovery mechanisms, including 1+1 protection, shared protection, etc., to ensure the reliability of data transmission.

7. Flexible bandwidth allocation: OTN supports multiple data rates and formats and can meet various bandwidth requirements, thereby providing flexible bandwidth allocation and network expansion capabilities.

The emergence of OTN technology is to solve some key problems in long-distance and large-capacity optical transmission, such as signal attenuation, dispersion, nonlinear effects, etc., and to provide a unified, efficient, and manageable transmission network. Through OTN, network operators can expand their networks more flexibly and economically to meet growing data demands.

What are the OTN transmission devices?

OTN transmission(Optical Transmission Network) equipment is mainly used to support long-distance, large-capacity optical signal transmission. These devices provide a unified network architecture for high-speed data transmission. The following are some common OTN transmission devices:

1. OTN Switch/Multiplexer (MUX/DEMUX): These devices are used to multiplex data streams from different inputs onto one output and demultiplex them at the other end. They ensure that multiple signals can be transmitted on a single fiber.

2.OTN Digital Cross-Connect (DXC): DXC is used to implement signal cross-connection and routing in optical transmission networks.

3. Optical amplifier (such as EDFA, Erbium Doped Fiber Amplifier):In order to ensure that the optical signal will not be attenuated during long-distance transmission, optical amplifiers are used to amplify the passing signal.

4. OTN Frame Forwarding Devices:These devices frame incoming data and forward it to the appropriate output.

5. DWDM equipment: Dense Wavelength Division Multiplexing (DWDM) equipment allows multiple optical wavelength signals to be transmitted on the same optical fiber, thus providing higher bandwidth.

6. OTN Terminal Devices:These devices are used to receive and send OTN frames. They perform frame mapping, multiplexing and frame processing.

7. OTN transmission protection equipment: In order to improve the reliability of the network, these devices provide optical path protection, halo protection and other functions.

8.Optical attenuator: In some cases, it may be necessary to reduce the intensity of the optical signal, in which case an optical attenuator will be used.

9. Optical Splitter/Combiner: These devices can split or combine optical signals.

10. Optical monitoring and diagnostic equipment: This type of equipment is used to monitor the performance and health of the OTN network in real time, such as optical power meters, OTDR (optical time domain reflectometer), etc.

11. Optical interface conversion equipment: Used to convert signals of other interface types (such as Ethernet, SDH/SONET) into OTN format.

12. Optical modulation/demodulation equipment:For some high-speed signals, it is necessary to use an optical modulator to convert the electrical signal into an optical signal, and use an optical demodulator to convert it back to an electrical signal at the receiving end.

These devices are typically produced by a variety of manufacturers and are used in a variety of network applications, from long-distance connections between cities to high-speed connections between data centers.
