OP3514
Optical Narrowcast Demux with BC/NC Combiner and Optical Power Level Monitoring |
The Model OP3514 is a combined narrowcast demultiplexer and
broadcast/narrowcast combiner with integrated power level monitoring capability.
The OP3514 features four optical input ports (one carrying the DWDM narrowcast services
and the other three for either a single four-way split or dual two-way splits of broadcast
services) and five output ports (one narrowcast services pass-through port and four
combined broadcast/narrowcast ports). Each OP3514 demultiplexes up to four DWDM
wavelengths and is available in various wavelength combinations.
One broadcast optical signal can be equally split four ways or, for
applications where lower splitting loss is mandated, each of two independent broadcast
signals can be split two ways, while the narrowcast carriers are separated by a
four-channel ITU–grid demultiplexer (with models available for both 100 GHz and 200 GHz
spaced ITU grid channels). Each narrowcast optical carrier is then multiplexed with one
of the common broadcast optical signals and passed to one of the four output ports. DWDM
optical carriers whose wavelengths are not dropped by the demux are passed through to the
DWDM output port.
As new video and/or data carriers are added to the system, or as the
configuration of the network is changed, the power levels of the optical carriers can
change. The optical power level monitoring feature of the OP3514 allows power levels to be
monitored remotely via SNMP interface to an element management system or locally via the
chassis power supply display or local craft port interface. The integration of demultiplexing,
splitting, combining and monitoring functions into one half-depth module simplifies DWDM
installations, improves efficiencies by reducing optical losses, dramatically reduces the
number of required fiber jumpers and requires less rack space than alternative equipment.
Features

and BC/NC combiner
• Non-service-interrupting local and remote power level monitoring
• Simplifies installation and reduces rack space requirements
• Eliminates most fiber jumpers normally associated with BC/NC combining
• Hot plug in/out
• Occupies one half-depth slot
