NETWORK + II Assigment Module 5

Would you use Singlemode or Multimode fiber optic cable to connect two LANS separated by 80 miles? Why?

multimode is good for high bandwidth at high speeds for intermediate distnances as in a building but becomes inconsistent for long runs. singlemode is good for long distance as it transfers data faster and even up to fifty times farther. keep in mind that the singlemode must not be pinched or crimped.

List the Nomenclature, common name, and media type for each of the network connectors types below: 

1. The BNC connector is pushed in and then locked onto the connection to hold it securely in place while connecting the core wire.

2. The straight tip (ST) connector uses a half-twist bayonet type of lock to hold it in place securely. ST connectors are most commonly used with singlemode fiber-optic cable that runs long distances. It resembles a small BNC connector, but it's generally made of hard plastic.

3.The RJ-45 connector is the most common of all network connectors. It is used to connect network interface cards (NICs) to hubs and/or switches. RJ-45s can also be used to connect network devices together for communication as well as control. The RJ-45 connector can contain and connect four pairs of wires, although they generally connect only two pairs.

4.The F-connector is a coaxial type connector that is commonly used with cable TV and cable modems. It will most likely be attached to an RG-6 or RG-59 (in older installations) cable and will provide a solid connection to facilitate the carrying of data or television signal.

5.DB-9 or recommended standard 232 (RS-232) was a cable standard commonly used for serial data signals connecting between data terminal and data communications equipment, such as when connecting a computer's serial port to an external modem. As you can imagine, it is used much less frequently today than it was in the past. Still, you should be able to recognize a DE-9 female connector as one that might be used in an RS-232 connection. These types of connections are being superseded in today's networks by more modern connectors such as USB.

6. The local connector (LC) connector is a fiber connector that is built into the body of an RJ-style jack. The LC connector is perfect for local connections in an organization's telecom room or network closet

7.The standard connector (SC) connector is a type of fiber-optic cable connector. It uses a push-pull connector mechanism similar to common audio and video plugs. SC connectors are most often used with multimode fiber-optic cable that is providing a backbone segment for a local area network.
