Point to point direct fiber optic connection has the advantages of easy management, no complex uplink synchronization technology, and automatic terminal identification. In addition, all the upstream bandwidth can be used by one terminal, which is very beneficial for bandwidth expansion. However, these advantages cannot offset its disadvantages in terms of device and fiber costs.

Ethernet+Media Converter is a transitional point-to-point FTTH scheme that uses Media Converter (MC) to convert electrical signals into optical signals for long-distance transmission. Among them, MC is a simple photoelectric/electro-optical converter that does not process the signal packet, so its cost is low. The advantage of this solution is that only MC needs to be added to existing Ethernet devices. The topology structure of the MC method is shown in Figure 3. For the currently popular 100 Mbps Ethernet network, a speed of 100 Mbps can also meet the needs of the access network, without the need to replace the network card that supports fiber optic transmission. Only MC needs to be added, which can reduce the cost of upgrading for users. This is a solution for the network during the transition period of point-to-point FTTH solution. Due to its relatively simple and inexpensive technical architecture, as well as direct integration with Ethernet networks, it once became the mainstream of FTTH in Japan. However, at the 2004 OFC conference, NTT announced that from now on, the FTTH standard in Japan will adopt a Point to Multi Point (P2MP) PON network mode, which will inevitably affect the future of MC.
