OP3524
Optical Narrowcast Demux with BC/NC Combiner and Optical Power Level Management |
The Model OP3524 is a combined narrowcast demultiplexer and
broadcast/narrowcast combiner with integrated power level monitoring and management
capabilities. The OP3524 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 OP3524
demultiplexes up to four DWDM wavelengths and is available in various wavelength
combinations.
One broadcast optical signal can be equally split four ways or 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. To ensure optimal network performance, the optical power level management feature
of the OP3524 allows power levels to be realigned remotely via SNMP interface to an
element management system or locally via the chassis power supply display or local craft
port interface. With the OP3524, broadband networks can be easily expanded by adding
optical wavelengths without needing to break physical connections or install optical
attenuators to realign the optical carrier power levels. By adding optical narrowcast
carriers, the OP3524 allows MSOs to offer new, revenue-generating services such as
digital video, video-on-demand, high-speed data and telephony, more easily and
cost-effectively than ever before.
