Is SDH transmssion system able to work on a very long non-REG distance?

Hey!

Normally the optical interfaces on the SDH equipment with bare optical modules are aiming at 120km maximum distance. If the distance is longer than 120km, we can use optical amplifiers and dispersion compensation modules to extend the transmission range. This technology is in fact used in the DWDM system, in this long distance SDH system, the SDH signal is forming a DWDM system with only one wavelength working.

For example, OSN3500 has many types of optical amplifiers (such as OBU1, OBU2, BPA, and Raman) and DCU dispersion compensation modules integrated, modules which can be managed directly from OSN3500 (which is very easy to use).

With the proper designing and arrangement of these modules, the transmission distance can reach more than 350km without a regenerating site. This technology is widely used in power grids and it has been proved to be effective.

if 10G link, the max distance should be 100~120Km, but if 2.5G or lower than 2.5G link, it support longer distance. currently, there is 380Km solution without relay site.
