FAQ about microQSFP
Q: What will the microQSFP (Micro Quad Small-Form-Factor Pluggable) MSA address and the microQSFP specification define? (Optical interfaces and copper?) A: The microQSFP MSA will develop a specification for a new compact module form factor, microQSFP, and make the specification available to the industry to promote industry adoption of compatible products that can be used […]
What Is Power-over-Ethernet?
PoE is short for Power Over Ethernet, is a methods of carrying both data and power to a device over copper cable. This is accomplished by running a twisted-pair copper cable, such as a Category 5 cable, from a device to a mid-span or endpoint, where the cable can be connectorized using standard RJ-45 or similar modular connectors. […]
Broadband over power line BPL
Broadband over power line, also called power line communications, refers to communicating over the existing aluminum and steel wire network, built by the power industry to provide electricity to businesses and homes, by transmitting data at medium and high frequencies. In the US, electric power is transmitted as a 60 Hz signal at various voltages […]

Diseño físico de conectores y adaptadores SC
Para nuevas instalaciones de cableados estructurados de telecomunicaciones, se recomienda utilizar los conectores y adaptadores SC, o cualquier otro conector y adaptador que cumpla con las especificaciones indicadas la figura A del estándar ANSI/EIA/TIA-568B.3 o equivalente, debido a que facilitan establecer y mantener la polarización correcta de las fibras utilizadas para la transmisión y recepción. […]
Fiber Considerations for 100 Gig – 3
Fiber Requirements Point to OM4 OM4 fiber offers a minimum effective modal bandwidth (EMB) of 4700 megahertz kilometer (MHz•km) at 850 nanometers (nm) compared with 2000 MHz•km for OM3. Both OM3 and OM4 fibers are 50 micron (µm) laser-optimized fibers with extended bandwidth and were designed to enhance the system cost benefits enabled by 850 […]
Fiber Considerations for 100 Gig – 2
Network Design and Layout As in previous Ethernet standards, 40 Gb/s and 100 Gb/s define several different Physical layer (PHY) implementations for transmitting information over various distances and media types. These media types include multimode and singlemode optical fiber cabling and some form of copper cabling. Additionally, various transceiver types are defined, distinguished by which […]
Fiber Considerations for 100 Gig – 1
The unrelenting demand for band width in the enterprise, and the resulting need for high-capacity, high-performance computing, is generating ever-faster network speeds. But 100 gigabits per second (Gb/s)? This would have seemed like a pipe dream 10 years ago, but it is now a fact of life in today’s enterprise networks and data centers. What, […]
Terabit super-channels squeeze 50 per cent more capacity from fibre
In the past week, there have been several successful demonstrations of terabit super-channel transmission using ultra-narrow channel spacings, which can increase overall system capacity by an additional 50 per cent compared to today’s commercial systems. ADVA Optical Networking and T-Systems, the systems and services division of Deutsche Telekom, took part in the ‘Terabit Demonstrator’ project, […]
