3.4.1 DCSĆNET FiberĆOptic Network System
Components
The DCSĆNET fiberĆoptic network system consists of the following
components:
Drop Cable The drop cable (M/N 57C366) is used to connect the Network
module to the transceiver.
A 9Ćpin DĆshell connector is provided at one end of the 3Ćfoot
(1Ćmeter) cable for connection to the PC3000. Terminations are
provided on the other end of the cable for connection to the
terminal strip on the transceiver.
StandĆAlone
FiberĆOptic
Transceiver
The StandĆAlone FiberĆOptic Transceiver (M/N 57C365) is
required at each slave network drop for connection to the
fiberĆoptic network. (A StandĆAlone Transceiver is required at
the master rack only if the rack and the fiberĆoptic hub cannot
be located together.) It performs the biĆdirectional conversion
between electrical and optical signals. Transceiver technical
specifications are listed in Appendix C.
The transceiver is designed to be panelĆmounted (vertically or
horizontally). Mounting holes are provided on flanges that
extend from both ends of the enclosure. Receive and transmit
ports labeled R" and T", respectively, are provided on one
end of the transceiver for connection to the fiberĆoptic link with
the transceiver hub. The transceiver is shipped with dust caps
covering the fiberĆoptic ports. The dust caps should not be
removed until the fiberĆoptic cables are installed, and should
be replaced if the cables are disconnected, to prevent dust
accumulation and the resulting loss of signal integrity.
WARNING
TURN OFF AND LOCKOUT OR TAG POWER TO BOTH THE
RACK CONTAINING THE NETWORK COMMUNICATIONS
MODULE AND THE TRANSCEIVER (RACKĆMOUNTED OR
STANDĆALONE) BEFORE VIEWING THE FIBERĆOPTIC
CABLE OR TRANSMITTER UNDER MAGNIFICATION.
VIEWING A POWERED FIBERĆOPTIC TRANSMITTER OR
CONNECTED CABLE UNDER MAGNIFICATION MAY
RESULT IN DAMAGE TO THE EYE. FOR ADDITIONAL
INFORMATION, REFER TO ANSI PUBLICATION
Z136.1Ć1981. FAILURE TO OBSERVE THIS PRECAUTION
COULD RESULT IN BODILY INJURY.
