Aurora Networks announces Optiplex II narrowcast demultiplexer, broadcast combiner with optical power level management.Aurora Networks, a developer and manufacturer of advanced optical transport and distribution systems for broadband networks  This article or section needs copy editing for grammar, style, cohesion, tone and/or spelling.You can assist by [ editing it] now. , has announced the availability of the new Optiplex OP3524 series narrowcast To transmit to selected individuals. Cable TV and satellite radio are examples of narrowcast services because they reach only their subscriber base. Mailing lists are another example. Contrast with broadcast. See multicast. demultiplexer, broadcast combiner. The Optiplex II module features optical power level management, which allows power levels to be realigned remotely, ensuring optimum network performance. The Aurora Optiplex is the only product of its type that can be managed remotely. The Optiplex demultiplexes four individual optical carriers containing narrowcast signals and combines them with a common broadcast optical signal. 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 management feature of the Optiplex II allows power levels to be realigned remotely via SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. interface to an element management system. Power levels can also be adjusted via the power supply display panel or through a local craft port interface. Levels can be adjusted on any individual wavelength in 0.1 dBm steps. Additionally, by combining these functions in one module, the cost and maintenance of eight optical patch cords A specific length of cable terminated at each end with a plug or socket. Patch cords or "patch cables" are typically short, but may come in lengths up to 100 feet or more. Any short cable of any type (telephone, audio, video, LAN, etc. are eliminated. "With the Optiplex II from Aurora, broadband networks can be easily expanded by adding optical wavelengths without the need to break physical connections or install optical attenuators An optical attenuator is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. They are commonly used in fiber optic communications. to realign re·a·lign tr.v. re·a·ligned, re·a·lign·ing, re·a·ligns 1. To put back into proper order or alignment. 2.

It used a single antenna at the highest location in the community in order to deliver a quality signal to homes in areas with hilly terrain or other interference. Products for Aurora Networks. "By adding optical narrowcast carriers, Optiplex II allows multiple system operators (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." The Optiplex II is a hot-swappable module that occupies one half-depth slot in the Aurora CH3000 Series high-density chassis. It typically resides in a hub site, although could also be located within the headend. The product is available now. |
