What Cabling Infrastructure Can Support 40G Data Center?

by Fiber-MART.COM Fiber connectivity in higher-speed active equipment tends to develop as more condensed and simplified with plug-and-play, hot-swap transceiver miniaturization. 1G and 10G networks commonly use SFP or SFP+(Small-form-factor pluggable plus). Interfaces of 40G is QSFP (Quad Small Form-factor Pluggable). The interface changes need different connectors to achieve network connectivity. [ Continue reading…]

Passive DWDM vs. Active DWDM

by Fiber-MART.COM DWDW is short for dense wavelength division multiplexing. It is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. It has revolutionized the transmission of information over long distances. DWDM [ Continue reading…]
