How To Avoid The 7 Most Costly Mistakes Of Upgrading Your Network To Optical Fiber - Part 2

Mistake #2: Preventing Migration

Fast Ethernet offers two fiber options. 100BASE-FX is the most common. It supports distances of up to 2,000 meters over multimode fiber but offers no 10/100 negotiation. To address the need for 10/100 auto-negotiation and to lower the cost of fiber connectivity, the industry is developing the 100BASE-SX standard. 100BASE-SX is limited to deployments of 300 meters or less, but since it allows using both 10 and 100 Mbps, conversion technology can be used to run the link at whatever speed is required.

Using a 10/100 SX converter allows you to future-proof your install. Take, for example, a 10/100 NIC (network interface card) plugged into a 10BASE-T hub with SX converters at either end, and the link runs at 10 Mbps. Replacing the 10BASE-T should cause the whole link to come up at 100 Mbps if the 10/100 SX media converter is used. The alternative is to buy a 10 Mbps converter for the 10 Mbps link and replace it when the upgrade is made. Although a bit more expensive than a 10 Mbps converter, an SX converter costs less than a 100BASE-FX converter.

While Fast Ethernet is good for now, mixed network topology eventually will have to be scaled to Gigabit Ethernet. Using a 4 Gigabit Ethernet Media Converter enables converting one or more 1000BASE-SX ports on a Gigabit Ethernet switch or 1000BASELX or use in campus area networks or other applications requiring the distance advantages of single mode fiber. It is only necessary to convert those ports required for backbone connection.

Ironically, it is often less expensive to purchase a multimode switch and an external multimode to single mode media converter, than it is to buy a switch with single mode installed internally.

Additionally, some Gigabit Ethernet electronics are only compatible with multimode fiber. In such an instance, a single mode to multimode media converter makes the connection. With single mode fiber in the backbone, copper or another medium to the desktop and media conversion tools providing connectivity between disparate technologies, the network manager can confidently plan for a future network incorporating Gigabit Ethernet.

Crystal Clear Fiber Optics

When it comes to a fiber optic network or a simple fiber optic cable connector, cleaning and maintenance is of immense importance. It not just ensures cost savings but also better and optimum usage of the network. Hence, it makes good networking sense to keep fiber optic set-up clean and contamination-free.

Cleaning of connector fiber optics helps in network quality. If one speaks to a variety of customers who have operated high-speed networks for years, one would get to know how important cleaning cartridge filter is or a ferrule cleaner to a network.

AEFOS is the company committed to development and manufacture of AFC 3000 ferrule cleaners for fiber optic industry having its usage across variety of industries such as aerospace, scientific research and even education. The product is an automatic cleaning device used to clean fiber optic cable connectors.

It comes with cool features. The design is unique and well thought-of, hence it can serve as a female and male ferrule cleaner. And since the device is based on dry cleaning process, if one runs out of cleaning fiber, one can see red signal around the spool via a window. The red warning suggests that the time has come for cleaning cartridge filter and changing it.

AEFOS’ AFC-3000 is patented in USA and Canada and comes with an easy to understand user manual. If you are a fiber optic technician one will take a few minutes to understand the easy-to-use design of this simple and immensely helpful product. One can get started by purchasing an AFC-3000 along with CFC-600 cartridge and a cleaning tip. That should set you up towards a contamination free fiber optic cable connectors and network.

So one can make optimum use of a high-speed network by cleaning filters and cartridges along with using probably the best ferrule cleaner around – AEFOS’ AFC-3000.

Logitech Z-5500 5.1 Surround Sound System connection issue to my VAIO AR21-S Laptop.?

Ive just bought a "Logitech Z-5500 THX-Certified 505-Watt 5.1 Digital Surround Sound Speaker System" At the moment im using a direct stereo cable from my laptop to the system but this way i cant use the THX, Dolby Digital and DTS features.

If your laptop has an Optical Out, why in hell are you not using it? Purchase that Toslink adapter and that cable and get some digital audio to those beautiful speakers! I don't see why it wouldn't work.
