Lightguide Jumpers 10
The DDM-2000 Multiplexers provide Lucent's 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
â
, FC-PC, or SC connectors
as needed. Both 0 dB and attenuating buildouts are supported.
The OC-1 and OC-3 lightguide interfaces use both single-mode and multimode
jumpers for connecting to and from the outside plant
LGX
â
panel and the
DDM-2000 OC-3 Multiplexer.
When the outside plant lightguide is multimode, a single-mode or multimode
jumper can be used between the
LGX
panel and the DDM-2000 OC-3 Multiplexer
on the transmit (OUT) side. Multimode must be used on the receive (IN) side of all
OLIUs.
When the outside plant lightguide is single-mode, a single-mode jumper must be
used for the transmit side and either single-mode or multimode jumpers can be
used for the receive side of all OLIUs (except the 24G-U/24H-U and 29G-U/
29H-U which requires single-mode fiber on both the transmit and receive sides
due to potential optical path degradations).
Regardless of the type of fiber in the outside plant, the 22D-U OLIUs, used for
intershelf OC-3/OC-12 interconnection, must be used with multimode jumpers on
the transmit side.
The 24G-U/24H-U and 29G-U/29H-U OLIU must be used with single mode fiber.
Lightguide jumpers can be ordered from Lucent. See the "OC-3 Ordering —
Miscellaneous Equipment and Tools" section for ordering information.
