Long Reach OC-12 Interface (29G-U/29H-U)
7
■
Optical/Copper Specifications
For direct optical loopbacks, at least 10 dB of optical attenuation is needed
for the 29G-U optical line. The distributed feedback laser supplies a NRZ-
coded signal. The 29G-U OLIU long reach OC-12 interface supports span
lengths up to 51 km, assuming 0.45 dB/km single-mode fiber (including
splices) and the span engineering rules outlined in Table 7-4 Transmit and
receive powers are referenced to points S and R as shown in Figure 7-51.
Table 7-3 and Table 7-4 provide detailed specifications and link budget
information for the 29G-U OLIU. Note that the 29G-U OLIU is not specified
to operate over multimode fiber.
For direct optical loopbacks, at least 10 dB of optical attenuation is needed
for the 29H-U line. The distributed feedback laser supplies a NRZ-coded
signal. The 29H-U OLIU long reach OC-12 interface supports span lengths
up to 96 km, assuming 0.25 dB/km single-mode fiber (including splices)
and the span engineering rules outlined in Table 7-4 Transmit and receive
powers are referenced to points S and R as shown in Figure 7-51.
Table 7-3 and Table 7-4 provide detailed specifications and link budget
information for the 29H-U OLIU. Note that the 29H-U OLIU is not specified
to operate over multimode fiber.
■
Alarm Thresholding
The following parameters are monitored at the OC-12 interface.
— Loss of signal (LOS)
— Loss of frame (LOF)
— Loss of pointer (LOP)
— Line AIS
— B2 thresholding signal fail
— B2 thresholding signal degrade. (B2 signal degrade thresholds are
user settable in the range from 10
-5
to 10
-9
BER.)
■
Performance Monitoring (see Table 7-5)
— Section SEFS
— Line parameter B2.
— STS pointer justifications (Release 15.0 and later).
