The Link Loss Budget is used to verify that the system’s maximum signal loss is within the required operating levels of the transmitter and receiver.

2. The Link Loss Budget is
used to verify that the
system’s maximum signal
loss is within the required
operating levels of the
transmitter and receiver.
,

3. The receiver’s operating
levels are determined by
the receiver’s sensitivity in
comparison to its dynamic
range.
,

4. The Receiver Sensitivity is
the lowest optical signal
that can be detected by
the receiver,

5. FIBER ATTENUATION
,

6. THIS IS AN INTRINSIC
LOSS THAT RESULTS
FROM LOSS OF SIGNAL
OVER CABLE DISTANCE,

7. @850nm 3.0db/km
@1300nm 3.0db/km
@1310nm 3.0db/km
@1550nm 0.4db/km
Attenuation at different wavelength

8. TIA/EIA STANDARDS
in MULTIMODE CABLES
50/125um @ 850nm is 3.5db/km
62.5/125um @ 850nm is 3.5db/km
================================
50/125um @ 130nm is 1.5db/km
50/125um @ 1300nm is 1.5db/km

9. TIA/EIA STANDARDS
in SINGLEMODE CABLES
OS 1 @ 1310 nm is 1.0 db/km
OS 1 @ 1550 nm is 1.0 db/km
================================
OS 2 @ 1310 nm is 0.5 db/km
OS 2 @ 1550 nm is 0.5 db/km
