HFC two-way network access scheme based on RFOG technology

Overview of solution benefits: Converged solution of traditional CMTS+CM solution and passive optical network architecture, which can save a lot of fibre resources. As the backhaul laser works in burst mode, it can effectively reduce the uplink convergence noise. As the fibre optic routing adopts the PON networking method, it greatly reduces the transmission line maintenance workload. There is already mature technical standard support (SCET officially issued the RFOG FTTH specification SCET 174-2010 in 2010). Overview of programme disadvantages: As the scheme is planned with reference to the network model of FTTH, the output level of the whole machine is defined at a relatively low level, and certain optimisation and improvement is required to popularise and promote it in the FTTB network. The RF detection circuit used to control the burst mode operation of the return laser needs to be further improved in terms of anti-interference capability. According to the definition of SCET 174-2010 standard, this scheme adopts 1-fibre 3-wave transmission scheme. However, due to the relatively high price of WDM devices and the fact that the minimum number of fibre optic cables in China is 2 cores, the dual-fibre transmission scheme will be more in line with the current national conditions.
