The optical transport network (OTN) is an international standard in the telecommunications network, with which carriers distribute information. OTN architecture is composed of three levels.

Plan b digitation will plan your optical network, beginning with the first level, the optical transmission section (OTS), to the next layer – the optical multiplex system (OMS) and the optical channel layer (OCh).

• OTM-1: 2,67 GBit/s optical fiber between two system components

• OTM-2: 10,7 Gbit/s multiplex-functionality of a DWDM connection between two network-hubs

• OTM-3: 43,0 GBit/s optical transmission between two users

Products that adhere to the standard OTN architecture are available from all main components manufacturers. Plan b digitation helps you make the right choices of products based on their knowledge and expertise.
