FTTO and passive OLANs generally use _______ connectors which are color-coded
_____________.
A. | Singlemode, beige | B. | Singlemode PC, beige | C. | Singlemode APC,
Green | D. | Any, blue |
|
|
|
2.
|
Connectors on reference patchcords for testing OLAN singlemode cable plants must
match the type of connector used on the cable plant, e.g. APC.

FTTD (contralized fiber) links using MM fiber should be tested at
_________nm.
A. | 850 | B. | 1300 | C. | 1310 | D. | 1310 and 1490 |
|
|

FTTO links using SM fiber should be tested at _________nm with a
_____source.
A. | 850, VCSEL | B. | 1300, LED | C. | 1310,
laser | D. | 1310 and 1490, laser |
|

The loss budget for a fiber optic cable plant includes __________.
A. | The loss of the total length of fiber | B. | The loss of all connectors and
spices | C. | The loss of any passive devices like splitters | D. | All of
these |
|
|
|
6.
|
Passive OLANs transmit at 1310nm upstream and 1490nm downstream. Since most
singlemode sources have 1310 and 1550nm lasers, it is acceptable to test at 1550nm instead of
1490nm.

OTDR testing of passive optical LANs can be tricky because of
__________.
A. | The short lengths of cable in passive OLANs may be less than the OTDR's
resolution | B. | Splitters have different traces upstream and downstream and may be hard to
interpret | C. | OTDRs will not find installation-caused stress points if the cables use
bend-insensitive fibers | D. | All of these |
