Optical Distribution Network (ODN) products are used for optical fiber cable connection and scheduling, they are applicable for optical fiber connecting point between the optical transmission network and equipment or between the access network and subscriber cable by. An Optical Distribution Network (ODN) is an important component within fiber access networks (FTTx). The ODN is responsible for carrying optical signals from the Optical Line Terminal (OLT) in the Central Office to the end-user's Optical Network Terminal (ONT). The ODN uses passive optical elements. With Huawei's core concept for ODN construction centering on full and dense coverage coupled with short and easy access, Huawei's ODN 3. 0 solution uses two transformative technologies to support five typical network scenarios. In the earliest FTTH solution, ODN 1. Acting as the physical “bridge” of a Passive Optical Network (PON), it determines signal quality, reach, cost efficiency, and. Grandway provides a full range of ODN optical distribution network products (ODF, FOSC, ODC, FDB, FTB, ONU) and customized services.
