SONET和OTN的区别

1.同步光网络(SONET)：
SONET 代表同步光网络。这是一种通信协议，由 Bellcore 开发，用于通过使用光纤在相对较大的距离上传输大量数据。通过使用它，多个数字数据流同时通过光纤传输。

2. 光传送网(OTN)：
OTN 代表光传输网络。这是一种用于通过光纤网络发送网络消息的协议。它旨在通过提供一个透明的框架来有效地承载不同的流量类型来解决这些问题。形成了两层交换(TDM 和 WSON)，并定义了传输、管理、监督、复用、路由和生存能力的功能。

SONET和OTN的区别：

S.No.	SONET	OTN
1.	Synchronous mapping of payloads.	Asynchronous mapping of payloads.
2.	It is designed to operates on multiple wavelength.	It is designed to operates on multiple wavelength(DWDM).
3.	It requires right timing distribution across network.	It does not require timing distribution.
4.	It was defined with fixed frame rates.	It was defined with fixed frame sizes.
5.	It is less efficiently than OTN.	It is much more efficiently than SONET.
6.	It performs multi stage multiplexing.	It performs single stage multiplexing.
7.	It scales to maximum of 40Gb/s.	It scales to 100Gb/s (or beyond).
8.	It does not has any standard FEC.	It has FEC size for error correction to correct 16 blocks per frames.
