Differences between G.657A2 and G.657B fibers

G.657 optical fibers provided by Huawei are named G.657B optical fibers and G.657A2 optical fibers. G.657B optical fibers are short-jacket optical fibers defined in ITU-T G.657 (12/2006). According to ITU-T G.657 (11/2009), these fibers are classified into G.657A1, G.657A2, G.657B2, and G.657B3 optical fibers. G.657B optical fibers provided by Huawei and the G.657A2 optical fibers are fully compatible and can be interconnected. These optical fibers are fully compatible with G.652D optical fibers. The compatibility between G.657B optical fibers that are not provided by Huawei and G.657A2 and G.652D optical fibers needs to be verified.
