OP-Smooth Computer Consultancy assists large enterprises in establishing machine rooms especially for server groups, which are protected by the indoor facilities of fire control (e.g. FM200), waterproofing, air-conditioning and UPS as constructed pursuant to a careful plan. In addition, we provide one-stop wiring services, including onsite assessment, consultancy and structured cabling solutions, so as to help our clients to connect voice and data applications in their offices and server rooms. And we provide Gigabit and Ethernet fiber optic systems in high quality.


The general difference between category 5e and category 6 is in the transmission performance, and extension of the allowed bandwidth from 100 MHz for category 5e to 200 MHz for category 6. This includes better insertion loss, near end crosstalk (NEXT), return loss, and equal level far end crosstalk (ELFEXT). Improvements, such as described, provide a higher signal-to-noise ratio, allowing greater reliability for current applications and higher data rates for future applications.


Optical fiber is rising in both telecommunication and data communication due to its unsurpassed advantages: faster speed with less attenuation, less impervious to electromagnetic interference (EMI), smaller size and greater information carrying capacity. The unceasing bandwidth needs, on the other hand, are also yielding significant growth in optical fiber demands. Let’s take a review of common fiber optic cable types, explore the advantages and disadvantage of optical fiber, and offer tips on selecting fiber optic cable.


Encryption means that the messages that are sent between your computer and the wireless router are in the form of a “secret code,” so that they cannot be read by anyone who doesn’t have the key to decipher the code. Most routers are shipped from the factory with encryption turned off by default, and it must be turned on when the network is set up. If an IT professional sets up the network, then chances are good that encryption has been enabled. However, there is no sure fire way to tell if this has happened.


Apart from monitoring the premises, CCTV cameras can help to deter crime. When you have a mounted alarm system at your home, you would easily be notified if an intruder tries to get inside your home. On the other hand, when the criminals know that there are CCTV cameras installed at your premises, they would avoid breaking inside your home. Look for a leading and reliable CCTV camera manufacturer when you want to buy such security cameras.
