Q

What is an F-connector?

A

A coaxial connector used with RG-6 or RG-59 cabling. Commonly used for cable TV and cable modem connections.

19
Q

What is a Local Connector (LC)?

A

It is a connector commonly found on MMF and SMF optic cables. Its small size allows a greater density of ports on a switch. It has a spring-loaded detent that holds it in place.

20
Q

What is a Straight Tip (ST) connector?

A

One of the most popular connectors used with single mode fiber optics. Found in both SMF and MMF cable installations. Will not come loose because of positive locking mechanism.

21
Q

What is a Standard Connector (SC)?

A

A square connector with a floating ferrule that contains the fibre-optic cable. Found in SMF and MMF, but most popular with MMF. Larger than most, uses a push-on/pull-off mating mechanism.

22
Q

What is a Mechanical Transfer Registered Jack (MTRJ)?

A

Resembles an RJ-45 connector and contains a transmit-and-recieve pair of fiber cables. Small size allows greater density of ports on a switch. Found in MMF and SMF optic cables.

23
Q

What is the job of a fiber-optic transceiver?

A

To convert between the internal electrical signalling of the network equipment and light.

24
Q

What is the job of a copper transceiver?

A

To convert between the Ethernet and the internal electrical signalling of the network equipment.

25
Q

What is a Small Form-Factor Pluggable (SFP) transceiver?

A

Is a hot-swappable module used for both giber-optic and copper media. Small design allows for high density of ports. Found in both MMF and SMF. Can support up to 1Gbps of network connectivity.

26
Q

What is a Small Form-Factor Pluggable+ (SFP+) transceiver?

A

Identical to SFP. Can support speeds of 10Gbps or higher (up to 400Gbps). Has the added benefit of providing controller data such as signal loss and TX/RX power.

27
Q

What is a Quad Small Form-Factor Pluggable (QSFP) transceiver?

A

Allows for hot-swappable operations. Used for high port density because of its size. The quad transceiver allows for 4x1 Gbps (4Gbps) operation. Can be purchased as a fanout cable, this separates each transceiver to a seperate connection.

28
Q

What is a Quad Small Form-Factor Pluggable+ (QSFP+) transceiver?

A

Allows for hot-swappable operations. Used for high port density because of its size. The quad transceiver allows for 4x10Gbps, and 4x25Gbps (40 Gbps and 100Gbps) operation.

29
Q

What is a Media Converter?

A

Used to convert from copper to fiber optic cable and back to copper. Can also be used to convert from MMF to SMF and vice versa.

30
Q

What is a Unidirectional Fiber Transceiver?

A

Reserves one tiber-optic strand for transmitting and the other for receiving.

31
Q

What is a Bidirectional Fiber Transceiver?

A

Allows for a single fiber-optic strand to both transmit and receive data.

32
Q

What are two common methods to multiplex several different wavelengths of light onto the same glass media at a time?

A

Coarse Wavelength Division Multiplexing (CWDM).
Dense Wavelength Division Multiplexing (DWDM).

33
Q

What are the specs of Coarse Wavelength Division Multiplexing (CWDM)?

A

Allows up to 18 seperate channels. Uses large chunks of light wave space. Achieves a nominal 10 Gbps per channel for Ethernet and 16 Gbps per channel for Fibre Channel.

34
Q

What are the specs of Dense Wavelength Division Multiplexing (DWDM)?

A

Allows up to 80 seperate channels. Uses narrow chunks of light wave space. Can deliver 100 Gbps per channel. Used in high-capacity applications.

35
Q

What is a Punchdown Block?

A

A central panel where wires are connected directly to the block to make the connection. Instead of a crimper, a punchdown tool is used.

36
Q

What is a 66 Block?

A

A punchdown block commonly used for analog wiring of telephone equipment. It’s main purpose is to supply a plain old telephone service to a business or apartment building.

37
Q

What is a 110 Block?

A

Commonly used for analog wiring of telephone equipment. Often one side will lead back to the private branch exchange (PBX) and the other side to the phone equipment; this is called a cross-connect.

38
Q

What is a Krone Block?

A

Often mistaken for a 110 block panel. It differs from the 110 block because the punchdown spades where the wire is punched down are larger and it requires a special Krone punchdown tool.

39
Q

What is a Building Industry Cross- Connect (BIX) punchdown block?

A

Created by Nortel in the 1970’s. The BIX is almost always found in Nortel phone switch installations. It is used for cross-connecting a 110 or 66 block that leads to the phone extension.

40
Q

What is a Patch Panel?

A

Commonly used in wiring closets as a diagnostic point for Ethernet network connections. The back side is punched down to the network cabling. The front side is connected with a patch cable to the network switching equipment.

41
Q

What is a Fiber Distribution Panel?

A

Used to terminate the individual fragile strands to a common fiber-optic connector. Fiber distribution panels serve two purposes: distributing the individual strands and serving as a diagnostic point for troubleshooting.

42
