transfer speed
The transmission speed refers to the number of Bit dogs that transmit it per second, and the enterprise MB/block is one of the key components of the optical fiber communication system system software. The composition of the optical module is a structured light module, the English name is OpticalModule. Optical, which means "eye vision, visual effect, electronic optical". To be precise, the optical module is a general name of various types of control modules. The actual includes: light acceptance control modules, light push control control modules, light collection and sending integrated control modules with light sharing control modules, etc. Nowadays, the light module that everyone is often said to be generally refers to the light charging and sending integrated control module (mold four channels) CWDM4 (coarsewavelengthds or GB/s. Key speed: 100M, Gigabit network card, and 10,000 mega.
2. Transmission spacing
The transmission spacing of the light module is divided into three types: long -distance, medium and long. Generally, 2km and the following are short routes, 10-20km are medium and long distances, 30km, 40km, and above are long -distance Shenzhen optical communication control module manufacturers Shenzhen optical communication control module manufacturer.
The transmission spacing of the optical module is limited. The key is that when the light signal light is not on in the fiber line, there will be a certain loss of Shenzhen optical communication control module manufacturer and scattering of Shenzhen optical communication control module.
East-westtraffic (total flow) accounts for about 85%of the big data center traffic. In 2021, the total traffic of the world's big data centers categorized the total traffic of the world's big data centers for 100G sales, and the CWDM4 became popular 100G. Mobile phone traffic has steadily increased, and the development trend of large data centers in import substitution and flat design development trends promotes the development trend of light modules to two levels: transmission speed requires upgrading, and the total demand for total number is 400G. When the company is transmitted in the fiber line, it is damaged due to the induction of the material and the leakage of the material. This part of the kinetic energy is accompanied by the increase in the transmission spacing at a certain proportion of loss.
The key to scattering is due to the different radio waves that are different from the wavelength of light wavelengths differently in the same substance, and then Shenzhen's optical communication control module manufacturer Shenzhen optical communication control module manufacturer causes the light signal lights to not be bright. The ingredients arrived at the coordinator at a different time because of the accumulation of the transmission spacing, causing the single pulse to broaden it, so that the data signal value cannot be distinguished.
Typical commodity: Lights Active Device: Laser generator (VCSEL, DFB direct laser generator, EML adjustment laser generator), light dissolving device (PMQ dissolution device, phase modulator, pressure -resistant strength demodigor) , Light detectors (PIN, APD), integrated components (related optical transcetors, column arrays), etc. Light -free device: optical isolation, light divided router, optical switch, and optical connector (MPO is excessively categorized again. Basically, if the packaging basically cooperates with some main parameters, the network status will be selected. Suitable optical modules to achieve different transmission spacing regulations.
