The data central office provides an equipment room for the broadband operator or ISP. The data switch, voice switch, video server and other value-added service devices are installed, and the Optical Line Terminal (OLT) is used to send diversified service signals to Optical Network Units (ONUs) of users through ODN.
The ODN central office product is connected to the OLT and outdoor optical cable. The fiber capacity of equipment room becomes larger and larger as optical access is promoted gradually, and the equipment room of central office for scale construction of FTTx raises higher requirements for later-stage maintenance management and ODF density.
To meet the large-scale optical access construction requirements of operators, we delivers the double-sided Optical Main Distribution Frame (OMDF) for facilitating patch cord management and the high-density Optical Distribution Frame (ODF) for improving the equipment room capacity and density.

ODF frame cabinet system
