The advantages and disadvantages of light advancing and copper retreating

Optimize the network structure, but the cost is higher.

The advantages of the fiber-in-copper-out technology are that it optimizes the network structure, greatly improves the broadband quality, and the equipment operates stably, revitalizes equipment resources, and reduces costs and maintenance expenses; the disadvantage is that there are still a large number of based on The business application of twisted-pair copper cables in the network is large-scale, scattered, complex to migrate, has a large business impact, and the replacement, migration and transformation costs are also high.

Optical fiber entry and copper exit refers to using optical fiber to access users in the broadband access mode, replacing the cables between the access computer room and access users, speeding up the transmission rate and increasing data traffic, and at the same time, A model that significantly reduces network construction costs.
