What is 5G Fronthaul,Middlehaul,Backhaul?

5G network has three parts, Access Network, Bearer Network, and Core Network. The access network is also Radio Access Network(RAN), which is mainly composed of base stations. Mobile communication architecture So what does the...

A Comprehensive Overview of APON,BPON,EPON,GPON

A Comprehensive Overview of APON,BPON,EPON,GPON

PON stands for passive optical network, which means that the ODN (optical distribution network) between the OLT (optical line terminal) and the ONU (optical network unit) does not have any active equipment, and only...

MEMS Optical Devices — MEMS OXC

MEMS Optical Devices — MEMS OXC

Application of OXC Optical cross connect (OXC) is a matrix switch usually with N×N ports. The OXC can be used to construct a CDC ROADM (Colorless, Directionless, and Contentionless Reconfigurable Optical Add/Drop Multiplexer), as...

What is Polarization Maintaining(PM) fiber connector?

What is Polarization Maintaining(PM) fiber connector?

Polarization maintaining(PM) optical fiber connectors are usually used for special applications, such as optical fiber sensing, interferometry, planar waveguides, coherent optical transmission, and long-distance bidirectional optical transmission systems. To understand polarization-maintaining connectors, we need...

What is AWG (Arrayed Waveguide Gratings)?

What is AWG (Arrayed Waveguide Gratings)?

Why is AWG demanded? As we know, DWDM technology enables transmission of dozens of wavelengths in a single fiber, which expands the capacity of optical fiber communication enormously. The first mux/demux modules for DWDM...
