If you are about to deploy an OTN network by yourself or get a customized OTN solution from solution suppliers, there are some details and requirements that you should know in advance.
How many spans do you have, and how far between each of the spans?
The specific distance your network transports will determine the fundamental equipment needed in the OTN system. Specifically, the transmission distance between each span will indicate whether the Dispersion Compensation Module (DCM) would be needed to compensate in the fiber optical link.
What’s your fiber type and the link loss (typical 0.25dB/KM)?
OTN solutions offered by solution suppliers can be tailored to both dual and single fiber types. And link loss is necessary for collocating the most appropriate optical transceivers and some active components such as EDFA amplifiers.
What’s the data rate between each span? And how many businesses do you plan to transmit?
To make clear the data rate and capacity for each span in your network are conducive to choosing the most practical types of MUX or OADM for your current OTN infrastructure. And a good acquisition of the number of businesses you are to deploy can pave the way for future network expansion.
