FIBER OPTICS – Optical passives
Arris’ optical passives |
SUWANEE, Ga. – Arris has introduced ergonomically-designed optical passives in the OM4100 node fiber tray and field splice enclosure packages within its 1 GHz CHP CORWave system. The optical passives allow plug and play features in multiple wavelength systems, which reduce deployment time with minimum service interruption, according to Arris. The CHP CORWave 1 GHz system, with this advancement in CORWave passives technology, is now in qualification testing or has been deployed at several of the largest North American MSOs, as well as a prominent European service provider, according to the company.
The CHP CORWave solution passives are designed to facilitate quick segmentation without costly fiber construction, and to be installed without the need for specialized equipment, fusion splices or complex fiber routings in the field. The passives also allow pay-as-you-grow upgrades – operators can install additional receivers and transmitters as they are needed. The test point of CORWave passives can be used to measure the optical power of both forward and reverse wavelengths and as an injection point to perform inspection, certification, troubleshooting and documentation of fiber cabling.

Terminalclosures
CLEVELAND, Ohio – Preformed Line Products (PLP) has introduced its Coyote Terminal Closure product line, which can be adapted as the network grows. The Terminal Closure line is available in single or dual chamber configurations. The externally-mounted OptiTap style hardened adapters allow for future installation of hardened drops without closure re-entry.
To add more flexibility to support closures deeper in the communications network, additional drop capacity can be achieved through cable entry ports in the closure base.
The closure family offers a flexible grommet system, which allows for the addition and removal of adapters and interchange covers. Changing installation needs can be addressed with no special tools required for assembly.

Headend analyzer
SAN JOSE, Calif. – Symmetricom Inc. has unveiled its Q-1200 digital/IP video headend analyzer, a scalable, multichannel video headend monitoring device that will be generally available this month.
Performing audio/video analysis on 400 video streams simultaneously and content analysis for up to 100 channels, the analyzer identifies video impairments from basic service issues to sophisticated video artifacts, such as channel audio and/or video dropout, black/blue screen, major blockiness, and more, according to the company. The Q-1200 also measures video/audio with a user-configurable sampling period for I frame/audio data for each channel.
“With its multichannel scalability, deep content analysis, and centralized element manager, our Q-1200 replaces the need for expensive ‘golden eye’ operations personnel, enabling operators to accurately and cost-effectively assure video quality at any headend location,” said Symmetricom Principal Technologist Dr. Stefan Winkler, in a statement.

MDU mini-nodes
ANJOU, QUEBEC, Canada – Electroline Equipment Inc. has unveiled its EDX-T series of MDU mini-nodes with configurations for GPON, RFoG and HFC architectures. The Tri-Plexer and laser configurations can accommodate up to four wavelengths on the primary port and two wavelengths on the ONT bypass port. A 1590 nm laser option will support RF return traffic from set-top boxes or cable modems. As a result, data GPON ONTs can be optically coupled with the EDX to provide two-way RF video service. Buildings without PON equipment can run the EDX on the same 1:32 split physical network. Additionally, systems that rely on a CMTS can use the RFoG configuration to operate on the same 1:32 PON physical layer. Apartment level video control can be added via the SuperCAT addressable system.
