Method for designing open type fused EOC

Abstract

The invention discloses a method for designing an open type fused EOC. The open type fused EOC comprises a high-frequency submodule, a low-frequency submodule, an ONU submodule and the like. An IP data signal is modulated into a high-frequency signal and a low-frequency signal through the high-frequency submodule and the low-frequency submodule respectively after entering an open type fused EOC device through the ONU submodule, and the high-frequency signal, the low-frequency signal and a CATV signal are transmitted to a user side through the same cable. The open type fused EOC integrates the technical advantages of a high-frequency module, a low-frequency module and other modules, and fuses high-frequency technical standards and low-frequency technical standards, as a result, equipment cost is reduced, the access bandwidth is increased, the number of access users is increased, design work at an earlier stage and project implementation difficulty at a middle stage are reduced, operation and maintenance management, expansion and upgrading at a later stage are facilitated, and the open type fused EOC is applicable to the situation that distance between a photoreceiver and a user is different and other complex HFC network environments.

Description

technical field [0001] The invention belongs to the technical field of telecommunication, in particular to an open fusion type EOC design method. Background technique [0002] On January 13, 2010, the State Council passed a policy aimed at accelerating the integration of the telecommunications network, the radio and television network and the Internet. In July 2010, the state confirmed the first batch of 12 triple play pilot cities including Beijing, Dalian and Harbin; on December 31, 2011, the list of the second batch of triple play pilot cities was announced, including 2 municipalities directly under the Central Government and 22 provincial capital cities 42 cities were selected, covering a population of more than 300 million. [0003] With the promulgation of the triple play policy, the NGB era of broadcasting and television officially started. NGB, as a next-generation radio and television network that combines wired and wireless networks throughout the entire network,...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages of the existing technology: 1. There are many radio and television EOC access solutions, and the standards are not uniform. There are various high and low frequency EOC equipment in the existing network, which is difficult to maintain and upgrade, and the operation cost is high; 2. A single high frequency EOC solution or low frequency EOC The average bandwidth per household of the solution is only 1-2M, and high-definition video services cannot be carried out on a large scale, and the number of covered users is relatively small, which cannot meet the expansion needs of new users

3. Equipment such as EOC, ONU, and optical receivers need to be planned and installed separately, which requires a large amount of construction and high difficulty

4. Both low-frequency EOC and high-frequency EOC have their own shortcomings. The disadvantage of low-frequency EOC is that there are more interference noises in the low-frequency band, and the requirements for anti-interference are higher. High-frequency signal attenuation in the cable network is large, the transmission distance is short, suitable for the network from the optical machine to the building
