22
Q

What is the largest impact on fiber optic performance

A

Optical cleaning and assembly technique

23
Q

ONU

A

Optical Network Unit

24
Q

What powers the Fiber to the Premise (FTTP) Optical Network Unit (ONU)?

A

12 VDC transformer

25
Q

Residential Optical Network Unit (ONU) that converts optical signal to RF and connects to existing coax.

A

RFoG (RF over Glass)

26
Q

Each optical tap port on a Network Access Point (NAP) represents a unique fiber strand and is assigned to ___.

A

A specific home.

27
Q

This will show a fiber assignment from the splitter cabinet to each home or address it serves.

A

Design Print or Cut Sheet

28
Q

What is the difference between a RFoG ONU and an EPON ONU?

A

RFoG converts optical signal to Broadband RF. EPON converts optical signal to Ethernet.

29
Q

The nominal Optical Power Input for a Fiber to the Premise (FTTP) RFoG Optical Network Unit (ONU).

A

0 to -6dBm

30
Q

What is the power output of the Flexpoint Power Supply that feeds power to the ONU?

A

12 VDC

31
Q

Because fiber drops come in pre-made lengths, you may have to store excess fiber in the ___.

A

The Pedestal or vault.

32
Q

During a FTTP installation, what are the two bonding options inside of the ONU enclosure?

A
  1. Install a ground block in the coax connected to the RF side of the ONU.2. Eliminate the ground block and connect the ground wire to the ground lug on the ONU.
33
Q

This service type provides a node at every residence

A

FTTP

34
Q

If the Status LED on the Aurora RFoG ONU is green, this means.

A

Optical Power Input is above -10 dBm

35
Q

The FTTP ONU’s two piece design has a lower door provided for access to ___.

A

The Ground Block

36
Q

The output of the Optical Network Unit (ONU) at a residence in a Fiber to the Premise (FTTP) plant can be one of these two.

A

Broadband RF or Ethernet

37
Q

The RF power level Output on the FTTP RFoG ONU at 1002Mhz.

A

19dBmV

38
Q

What must be done with the fiber drop before you pull it through the conduit?

A

Unspool it

39
Q

This must be done each and every time an optical drop connection is made, even if it’s a brand new install with brand new equipment.

A

Must be cleaned

40
Q

What is typical loss for fiber optic cable?

A

1 dB per 3000 feet

41
Q

What is the angle on an APC connector?

A

8 degrees

42
Q

What is the benefit of using APC connectors?

A

Reduced back reflection and improved power transfer

43
Q

What should the upstream transmit level be at the ONU?

A

3 dBm plus or minus 1 dBm at 1610 nm

44
Q

What color is a UPC housing?

A

Blue

45
Q

What color is an APC housing?

A

Green

46
Q

The engineering standard for FTTP requires that this be installed at the output of the ONU.

A

A 4 way splitter at minimum

47
Q

What is the preferred method of powering the ONU and why?

A

Dedicated. That way there is no power loss when testing levels

48
Q

What is the max length between ONU and power supply?

A

50 feet

49
Q

RFOG power supplies shall not be installed in

A

Attics or crawl spaces.

50
Q

What is unit of measurement for optical power?

A

dBm

51
Q

What are the four components of a fiber drop?

A

Toning conductor, protective jacket, strength member, fiber optic strand.
