1. Cable failureFiber optical cable interruption leads to equipment without light, or cable damage causes excessive light attenuation. This kind of failure has a large impact, which can easily lead to no access to a large number of users.When such a failure occurs, the number and distribution of the

When operating the WDM system, make sure to pay extra attention to the following parameters:1. wavelengthA wavelength is a distance traveled by a wave in a vibration period. The wavelength λm of the monochromatic light propagating in the optical fiber is represented by the following formula:λm = λ /

Optical splitter is an essential part of PON network. The famous passive optical network structure“point to multipoints” of PON network is formed by optical splitter which evenly distributes light power in the direction of downstream and aggregates the light power in the upstream direction. The majo

For solving the shortage of optical fiber resource in the construction of FTTH, making the best use of the bandwidth of optical fiber, enhancing the reliability of network, PON( Passive Optical Network) technology has been developed and adopted into construction of FTTH, and security network monitor

Optical network refers to the conversion between optical and electrical signal at the input port and output port, and is always in the form of light in the network transmission and exchange process. Light source is the heart of optical fiber communication, the type and performance of the light sourc

Definition:GPON stands for Gigabit Passive Optical Networks. GPON is defined by ITU-T recommendation series G.984.1 through G.984.6. GPON can transport not only Ethernet, but also ATM and TDM (PSTN, ISDN, E1 and E3) traffic. GPON network consists of mainly two active transmission equipments, namely-

PON is Passive Optical Network. This is a telecommunications technology that implements a point-to-multi-point architecture, in which unpowered Fiber Optic Splitters are used to enable a single optical fiber to serve multiple end-points such as customers, without having to provision individual fiber
