By placing booster optical amplifier, optical line amplifier and pre-amplifier in different position of a DWDM link, the possible network reach extension can be achieved.
How to Set up EDFA for DWDM Network Extension?
Booster for 10 Gbps point-to-point connections up to 170 km
Distances of optical transmission systems can be extended by using EDFA. Three different EDFA types can be used depending on the required distance and existing locations. Simply by putting a booster optical amplifier at the beginning of a DWDM link, up to 170 km can be accomplished in a point-to-point connection.
Pre-amplifier ensures up to 250km reach without any in-line amplifier
As the booster amplifier set at the beginning extends the link reach to 170 km, with the additional use of a pre-amplifier at the end of a transmission, the achievable distance of the entire system can be increased up to 250 km.
Single in-line amplifier for 400km transmission even With100 Gbps
Installing an EDFA at one repeater site, a distance of up to 400 km can be realized. And this can be further extended if more repeater sites are used to place optical line amplifier. All three types of amplifiers are already designed to support 100 Gbps bandwidth for realizing up to 1000 km in a point-to-point connection. For this purpose multiple repeater sites and a Forward-Error-Correction (FEC) integrated in the used optics are required.
Appropriate deployment of EDFA as booster, in-line amplifier and pre-amplifier in a DWDM link contributes to optimize network performance for extending the reach. Which also increases data capacity required for current and future optical communication system. Hope the discussion in this article is informative enough to get a better understanding of EDFA optical amplifier.
