Who conducted the tour? Tour Guide: Howard Streby (Networking/Telecommunications Specialist) Michelle Wong

Difference between Cat 5, Cat 5e and Cat 6? Can handle 10/100 Mbps speeds (Fast Ethernet) up to 100 MHz bandwidth. Very slow and obsolete compared to new speeds out now Cat 5e: Currently the most commonly used in new installations Better at preventing signals on different circuits/channels from interfering Can handle 1000 Mbps speeds at 100 MHz. Cat 6: Capable to handle up to 10 gigabit Ethernet at 250 MHz Has internal separator that isolates pairs from one another http://www.cableorganizer.com/articles/cat5-cat5e-cat6.htm Michelle Wong

What are pros and cons of fiber optic cables? Offers much larger transmission distance than copper cabling Glass fiber costs have fallen Much more bandwidth per cable than copper cables Once fiber’s installed, no need to re-install new cables for awhile Fiber’s immune to external radio frequency or electromagnetic interference, unlike copper  Requires special training and equipment to fix If you compare patch cabling and network switches, fiber is more expensive http://www.l-com.com/content/Article.aspx?Type=N&ID=10318 Michelle Wong

What is Multi- mode fiber? Has large diametral core allowing multiple modes of light to transmit So, number of light reflections created as the light passes through increases Creating the ability for more data to pass through at a given time Because of the high dispersion and attenuation rate, the quality of the signal is reduced over long distances This application is usually used for short distance, data and audio/video applications in LANs Multimode fiber is usually 50/125 and 62.5/125 Means that the core to cladding diameter ratio is 50 microns to 125 microns and 62.5 microns to 125 microns http://www.multicominc.com/active/manufacturer/multicom/Fiber%20 Optics/singlemode-multimode.html Michelle Wong

Did touring the network facility increase or decrease your interest in Network Administration or Engineering as a possible career? Why? Touring the network facility decreased my interest in Network Administration or engineering There’s many different fundamental skills to be adept in, in order to succeed in this field Michelle Wong
