Long Reach 1310 nm OC-12 Interface (23G/23G-U
OLIU)
1
0
The DDM-2000 OC-12 Multiplexer supports a 1310 nm OC-12 high-speed
interface that is fully SONET-compliant. The nominal OC-12 line rate is 622.08
Mb/s.
■
Optical Specification
The OLIU photonics meet or exceed SONET long reach specifications
(TR-LR-1 MLM category). The multilongitudinal mode laser transmitter
supplies an NRZ-coded signal. The receiver requires the use of an external
attenuator for direct optical loopback.
The 23G/23G-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 10-8. Transmit and receive
powers are referenced to points S and R as shown in Figure 10-1.

Laser bias current is monitored on the 23G/23G-U OLIU.
Long Reach 1550 nm OC-12 Interface (23H/23H-U
OLIU)
1
0
The DDM-2000 OC-12 Multiplexer supports a 1550 nm OC-12 long reach high-
speed interface for controlled environments. The nominal OC-12 line rate is
622.08 Mb/s.
■
Optical Specification
The single longitudinal mode laser transmitter supplies an NRZ-coded
signal. The receiver requires the use of an external attenuator for direct
optical loopback.
The 23H/23H-U OLIU long reach OC-12 interface supports span lengths
up to 100 km, assuming single-mode fiber with total dispersion of less than
1800 ps/nm and the span engineering rules outlined in Table 10-8.
Transmit and receive powers are referenced to points S and R as shown in
Figure 10-1.
