ITU-T G.709.5 PDF

Recommendation ITU-T G.709.5 specifies a set of interoperable flexible optical transport network (FlexO) short-reach interfaces. The rates in scope for FlexO-x-<int> are 100G, 200G, 400G and 800G (x=1, 2, 4 and 8). This Recommendation specifies the structure using forward error correction (FEC) code with a coding gain suitable for short-reach applications, and references common elements from [ITU-T G.709.1].

The types of FlexO short-reach interfaces that can serve as FlexO-x-RS-m interface group members are covered by application codes which are at the time of publication: 4I1-9D1F, 4L1-9C1F, C4S1-9D1F, 4L1-9D1F, C4S1-4D1F, 8R1-4D1F, 4I1-4D1F and 8I1-4D1F. These application codes are presented in [ITU-T G.695] and [ITU-T G.959.1].
