The DDM-2000 OC-12 Multiplexer supports OC-12 long-reach applications at
1310 nm using the 23G/23G-U OLIU and at 1550 nm applications using the 23H/
23H-U OLIU. The DDM-2000 OC-12 Multiplexer also supports OC-3 optical
extensions using the 21G/21G-U/21G2-U and 21D/21D-U (IS-3) OLIUs. The 21G/
21G-U/21G2-U OLIU is fully SONET compliant. The 21D/21D-U OLIU is a low-
cost IS-3 low-speed interface used primarily to interconnect the DDM-2000 OC-3
Multiplexer to the DDM-2000 OC-12 Multiplexer at the same site. The nominal
OC-3 and IS-3 line rates are 155.520 Mb/s.

The DDM-2000 OC-3 and OC-12 Multiplexers provide Lucent Technologies’
universal optical connector on all OLIUs. The universal optical connectors are
receptacles on the faceplate of the OLIUs that allow a single OLIU to support
either
ST
®
, FC-PC, or SC connectors as needed. Both 0 dB and attenuating
buildouts are supported.
To prevent potential degradations, the DDM-2000 OC-12 lightguide interface
requires single-mode jumpers for connecting to and from the outside plant
LGX
®
panel and the DDM-2000 OC-12 for all OLIUs, except the 21D/21D-U OLIU.
The 21D/21D-U OLIU, used for intershelf OC-3/OC-12 interconnection, must use
multimode jumpers on the transmit and receive sides.
Lightguide jumpers can be ordered from Lucent. See the "OC-12 Ordering —
Miscellaneous Equipment and Tools" section of 363-206-200
DDM-2000 OC-3
and OC-12 Multiplexers Applications, Planning, and Ordering Guide, for ordering
information.
