5G transport optics must follow the RAN architecture Optical modules used in a 5G transport network cannot be selected only by a nominal data rate or a familiar form factor. The correct interface depends on the radio architecture, functional split, transport segment, endpoint equipment, synchronizat...

Vietnam International Communication Exhibition 2019 Exhibition Date: June 6th - June 8th, 2019 Exhibition Period: Once a year Location: Ho Chi Minh City, Vietnam Saigon Convention and Exhibition Center (SECC) Organizers: Vietnam Ministry of Information and Communication, Ministry of Industry and Tra...

DWDM networks are designed around controlled spectrum and optical paths A dense wavelength-division multiplexing (DWDM) network carries multiple optical channels over shared fiber infrastructure. Its value comes from using spectrum in a planned, repeatable way—not from placing several colored transc...

What a CWDM mux/demux does in an optical link A coarse wavelength-division multiplexing (CWDM) multiplexer/demultiplexer is a passive optical component that combines multiple wavelength channels onto a common fiber path and separates those channels again at the far end. It can help increase the use ...

What wavelength-division multiplexing does Wavelength-division multiplexing (WDM) is a method of carrying multiple optical signals on one fiber by assigning each signal a different wavelength. At the transmitting side, optical signals are combined by a multiplexer. At the receiving side, a demultipl...

Optical communication systems are end-to-end engineered networks An optical communication system moves information over fiber by combining active electronics, pluggable or fixed optical transceivers, fiber infrastructure, connectors, passive optical components, transport equipment, and operational m...

A 10G-to-25G upgrade is a link and capacity migration Moving server-facing or aggregation links from 10GbE to 25GbE is a network-capacity project, not a “network transformer” product change. The upgrade affects endpoint ports, NICs, switches, software images, optics or cables, fiber channels, FEC se...

Transceiver cost should be evaluated as total link cost The purchase price of a pluggable transceiver is only one part of the cost of a network link. The total cost includes the selected module or cable, host compatibility validation, fiber or copper channel, patching and installation labor, power a...

Last weekend,TOPSTAR went to Lianhua Park for volunteer work . As we climbed the mountain, we picked up the rubbish and put it in the trash for protecting the environment. Lianhua Park is the highest outdoor park in Shenzhen city , Dengxiaoping bronze statue stands in the middle of the square. The h...
