Data centers are comprised of a high speed, high demand networking communication systems capable of handling the traffic for Storage Area Networks (SAN), Network Attached Storage (NAS), file/ application/web server farms, and other components located in the controlled environment. The control of the environment relates to humidity, flood, electrical, temperature, fire controls, and of course, physical access. Communication in […]

Data Center Storage Network Technology Introduction
Storage network technology has developed in the following three main configurations: Direct Attached Storage (DAS), Network Attached Storage (NAS), and Storage Area Networks (SAN). Direct Attached Storage (DAS) DAS is the traditional method of locally attaching storage devices to servers via a direct communication path between the server and storage devices. As shown in Figure […]
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 […]
Migrating to 40 and 100G with OM3 and OM4 connectivity
With the continued requirement for expansion and scalability in the data center, cabling infrastructures must provide reliability, manageability and flexibility. Deployment of an optical connectivity solution allows for an infrastructure that meets these requirements for current and future data rates. A key factor when choosing the type of optical connectivity is scalability. Scalability refers to […]
Intelligent Category 8 plug with integral circuit board technology
Optical Cable Corporation (OCC) announced that it is introducing a new Category 8 RJ45 plug with integral circuit board technology that provides advanced control of crosstalk, return loss and other impediments, “ensuring consistent performance at higher frequencies up to 2000 MHz.” The company continued, “Category 8 Ethernet cable will play a major role in meeting […]
Why MPO/MTP Connector End Face Geometry is Important?
End face geometry is an essential characteristic of repeatable and reliable optical fiber connections. Overall performance of fiber optic connectivity depends on the mechanical characteristics that control alignment and physical contact of the fiber cores. End face geometry parameters for MPO/MTP connectivity include: Angle of the polish – Horizontal or X axis (RX and GX) […]
40 Gigabit Duplex Fiber Solutions
There’s been a lot of talk lately surrounding bidirectional 40 Gb/s duplex applications, or BiDi for short. Currently offered as a solution by Cisco®, BiDi runs over duplex OM3 or OM4 multimode fiber using QSFP modules and wavelength division multiplexing (WDM) technology. It features two 20 Gb/s channels, each transmitting and receiving simultaneously over two […]
Will XG-PON 10G GPON enough for us?
Based on the FTTH Councils statistics, there are more than 35.9million FTTH and FTTB subscribers in Europe Continent, even though we are still developing GPON or GEPON network, but we still would like to discuss whether 10G XG-PON could meet our bandwidth demand in the future. Currently, China Telecom, Telephonic, Verizon etc, the main telecom […]
What is ITU-T G.654 Fiber
ITU-T Recommend G.654 fiber is a cut-off shifted single-mode optical fiber especially used for high bandwidth long distance transmission. The G. 654 fiber is a single mode optical fiber and cable which has the zero-dispersion wavelengths around 1300nm, the fiber with loss minimized and cut-off wavelength shifted at around 1550nm. the fiber standard was firstly […]
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.
