Optical Distribution Frame (ODF) is used for the termination and distribution of central office backbone optical cables in optical fiber communication systems, and can easily realize the connection, distribution and scheduling of optical fiber lines.
With the increasing degree of network integration, an optical-digital hybrid distribution frame integrating ODF, DDF, and power distribution units has appeared, which is suitable for fiber-to-community, fiber-to-user, fiber-to-building, remote module office and wireless Small and medium-sized distribution systems for base stations.
