SFP transceivers have many different transmit and receive types, and users can choose the appropriate transceiver for each link to provide "optical performance" based on available fiber types, such as multimode or single-mode fiber. SFP transceivers also provide copper interfaces, enabling host devices designed primarily for optical fiber communications to communicate over UTP network cables.
There are also wavelength division multiplexing (CWDM) and single fiber "bi-directional" (1310 to 1490nm wavelength uplink / downlink) SFP. Most optical SFP transceivers support SFF-8472 (industry standard multilateral protocol). According to the SFF-8472 protocol, digital diagnostic monitoring (DDM, Digital Diagnostic Monitor) must be supported. This feature enables end users to detect SFP parameters in real time, such as the five basic monitoring quantities: Temperature, Vcc, Tx Bias Current, Tx Power, Rx Power.
As more and more companies introduce improved FTTH networks, smart homes have recently become mainstream. With the growth of bandwidth demand, FTTH operators need to provide higher quality services and products. The global fiber-to-the-home (FTTH) market is expected to grow at a fairly rapid rate during the forecast period from 2021 to 2026.
Fiber-to-the-home (FTTH) market growth-the growing use of fiber-to-the-home (FTTH) in TV, VOIP, games, LAN services, distance education, smart home and other industries is driving the growth of the global fiber-to-the-home (FTTH) market. Individual devices connected to the Internet do not require high bandwidth. However, smart homes pose challenges to operators. As a result, users' demand for high-speed Internet is increasing rapidly and will continue to maintain this trend in the near future.
The telecommunications infrastructure is the physical medium through which all Internet traffic flows. This includes telephone lines, cables (including submarine cables), satellite, microwave and mobile technologies, such as fifth-generation (5G) mobile networks. Using power line technology, even standard power grids can be used to relay Internet traffic. Innovative wireless solutions such as drones are also being gradually deployed.
Therefore, the Internet is a giant network that connects devices in different geographical areas. The user's device will wirelessly transmit information packets over the cellular network. These packets will then be routed between the network and each connected network via Ethernet, coaxial, and land, underground, or submarine cables until the packet reaches the destination server. this process does not necessarily follow the exact same route.
The 400G optical module has a transmission rate of 400G, which was born to adapt to the network market of 100M, 1G, 25G, 40G to 100G, 400G, and even 1T. 400G optical modules play a vital role and influence in the construction of 400G network systems.
Compared with 10G, 25G and 40G optical modules, the arrival of 400G optical modules will enable optical communications to enter a new era. Optical communications are transforming from single-carrier modulation coherent detection of low-end optical modules to polarization multiplexing multi-carrier applications.
The main function of 400G optical modules is to improve data throughput and maximize the bandwidth and port density of the data center. The future trend of 400G optical modules is to achieve wide gain, low noise, miniaturization and integration, and to provide high-quality optical communication modules for next-generation wireless networks and ultra-large data centers.
Although only one optical chip is used in the 400G optical module, the cost is high. In 10G/25G optical modules, the cost of optical chips accounts for about 30%; in 40G/100G optical modules, the cost of optical chips accounts for about 50%; and in 400G optical modules, the cost of optical chips is as high as 70%.

In the current market context, the demand for bandwidth in ultra-large data centers is growing, and 400G optical communication modules have become the best choice for improving system performance and reducing bandwidth costs. The emergence of 5G networks will become another positive factor driving the market value of 400G optical modules.
