Installing VCE components
Video Codec Enclosure (VCE) 323-3221-291 Rel 1.0 Standard
Procedure 3-3
Connecting optical carrier facilities to a DV-OC3 unit
A VCE can be equipped with an optional DV-OC3 optical interface unit. This
unit will transmit and receive optically-encoded OC3 signals. Input and output
OC3 fiber optic connections are made using optical connectors at the front of
a DV-OC3 unit. Connecting the optical signals involves cleaning and
assembling FC, ST, or SC type connectors. For more information on the
DV-OC3 unit, see the
DV-45 DV-OC3 Reference Manual
, PEC NT2H7908.
Note:
When errors occur during testing or in-service operation, clean the
DV-OC3 unit optical connectors.
Requirements
Prior to carrying out this procedure on an in-service system, you must:
•
ensure that traffic has been removed from the optical interface, as this
procedure requires disconnecting the fiber from the DV-OC3 unit.

DANGER
Risk of eye injury
At all times when handling optical fibers, follow the safety
procedures in “Observing safety guidelines” on page 4-1 of
this document, and those recommended by your company.
Avoid direct exposure to laser beam or fiber. Invisible light
that can blind is present. Keep all optical connectors capped.
