Important technical indicators of Fibconet fiber optic splitter Hplc flow splitter

Optical splitter is one of the important passive components in optical fiber links, which mainly play the role of splitting light. It is generally used to split optical signals between the optical line terminal OLT of the passive optical network and the optical network terminal ONU. hplc flow splitter hplc flow splitter
An optical splitter distributes the transmitted optical signal in one optical fiber to multiple optical fibers. There are various allocation forms, 1×2, 1×4, 1×N, or 2×4, M×N. The general architecture of FTTH is: OLT (computer room central office) – ODN (passive optical network distribution system) – ONU (user end), in which the optical splitter is applied in the ODN to realize that multiple end users share one PON interface. In the PON structure, when the distribution of buildings is scattered and irregular, such as the distribution of villas, the distance is far, and the density of users is low, the centralized light splitting method can make full use of resources and cover the surrounding area. hplc flow splitter hplc flow splitter
In a passive optical network, only one optical splitter may be used, or multiple optical splitters may be used together to split optical signals. hplc flow splitter hplc flow splitter
The performance indicators that affect the optical splitter generally include the following: Insertion loss The insertion loss of a fiber optic splitter refers to the number of dB of each output relative to the input optical loss. Generally speaking, the smaller the insertion loss value, the Spectral ratio The splitting ratio is defined as the output power ratio of each output port of the fiber splitter. Usually, the splitting ratio of PLC optical splitter is evenly distributed, and the splitting ratio of fused taper optical splitter can be unequally divided. The specific ratio setting of the splitting ratio is related to the wavelength of the transmitted light. For example, when an optical branch transmits light of 1.31 μm, the splitting ratio of the two output ends is 50:50; when it transmits light of 1.5 μm, it changes. It is 70:30 (the reason why this happens is that the optical fiber splitter has a certain bandwidth, that is, the frequency bandwidth of the transmitted optical signal when the splitting ratio is basically unchanged). isolation Isolation refers to the isolation ability of a certain optical path of a fiber optic splitter to optical signals in other optical paths. return loss Return loss, also known as reflection loss, refers to the power loss in an optical signal returned or reflected by a discontinuity in an optical fiber or transmission line. The higher the return loss, the better to reduce the impact of reflected light on the light source and system. hplc flow splitter hplc flow splitter
In addition, uniformity, directivity, PDL polarization loss, etc. are also parameters that affect the performance of the optical splitter. Optical fiber splitter is one of the most important passive devices in optical fiber links, especially suitable for connecting MDF and terminal equipment to distribute optical signals in passive optical networks (EPON, GPON, BPON, FTTX, FTTH, etc.). hplc flow splitter hplc flow splitter
