Bittree’s fiber-optic feed-through patch panel enclosure simplifies IT convergence
Addressing the convergence of IT with the video and audio operations associated with its core markets, media infrastructure provider Bittree announced the launch of its DSFB124NL series of next-generation patch panel enclosures. The feed-through, slide-out enclosure is billed as ideal for customers managing interconnections and crossconnections within telecom rooms and data centers, as well as in TV and radio facilities, recording studios, sports and live event venues, and various commercial AV architectures.
The first product in the series, the DSFB124NL-ST, is now shipping and accommodates high-density, simplex ST-to-ST connections. A second version, the DSFB124NL-LC will follow to accommodate duplex LC-to-LC connections. Both products will accommodate singlemode and multimode fiber applications, while its compact 1RU form factor enables high-density 24-position patching—an important benefit in facilities with limited rack space, notes the company.
Unlike previous-generation Bittree enclosures, the new DSFB124NL series includes steel gliding rails for easier access to connections, instead of the friction-based trays of the past. The gliding trays offer the benefit of smooth movement and steady-locking positions, simplifying access between ports as technicians move, add or make changes to the fiber-optic network. The enclosure comes with grommets, cable strain reliefs and bend radius guides, along with knock-out positions available on all four sides, whereby technicians can easily accommodate any demanding installation.
The products are built using a cold-rolled steel construction with a durable black powder-coat finish, ensuring a highly durable and reliable product design. The unit’s fold-down, clear-red acrylic front and rear doors additionally enable visual inspection of the patch interface to monitor connections and performance.
“This new series is a very timely solution, given its value for customers working through an IT convergence project,” comments Bryan Carpenter, senior sales consultant, Bittree. “In a broadcast facility or venue working with singlemode fiber over video lines, everything can run to one Bittree panel for distribution. In a data center or data-centric application where singlemode is preferable for longer distances, this is a perfect server-to-machine solution to interconnect backbone cabling to active equipment, or crossconnect to a main or horizontal distribution system. In any scenario, the DSFB124NL enclosure is built with connection to a core switch and/or routing system in mind and makes life even easier for the technicians that install and manage the entire ecosystem.”
Single-pair connector designs from CommScope, Harting chosen as standard interfaces
In a round of voting that concluded in August, the standards-development committee ISO/IEC JTC 1/SC 25 Interconnection of Information Technology Equipment, selected two single-pair connector designs as standard interfaces. Committee members chose one design, from CommScope, for use in MICE1 environments and the other design, from Harting, for MICE2/MICE3 environments.
MICE is an acronym for mechanical, ingress, climatic, and electromagnetic. The higher the number, the more severe the environment. In practical application, an example of a MICE1 (M1I1C1E1) environment is commercial office space.
When the Telecommunications Industry Association (TIA) TR-42.7 Telecommunications Copper Cabling Systems Subcommittee met the week of October 1, it also selected the CommScope and Harting designs as its recommended interfaces.
In materials presented to ISO/IEC JTC 1/SC 25, CommScope described its LC-style connector as one that “allows many versions and a rich innovation platform.” The company further stated that the connector’s “low part count and complexity will enable easy economic transition from 1-pair connectors currently in use (screw terminals) and lead to widespread adoption and growth.” Plus, according to CommScope, “Field installation with simple tools will enable installation in ceiling spaces and other difficult areas … contact wiping surfaces and resting surface concept similar to RJ45 will ensure reliable and robust performance.”
In its presentation to ISO/IEC JTC 1/SC 25, Harting explained its connector “is designed especially for MICE3 applications.” It is rated up to IP65/67, the company said, adding that the connector features “one MDI [medium dependent interface] design for PCB sockets, plug versions with IDC or crimp termination, and sockets for cabling platform for a wide variety of products [including] MDI sockets, plugs, sockets, bulkheads, adapters, cords.”
The connector uses already-existing M8 and M12 housings, which Harting says enable simple implementation in devices and other products. The connector provides transmission performance up to 600 MHz in a fully shielded design, and supports Power over Data Lines as well as remote powering for 1-kilometer applications, according to IEEE 802.3cg.
That standard—IEEE 802.3cg—is currently in draft and will define 10-Mbit/sec single-pair Ethernet. Based on the ISO/IEC voting and selection of these two connector interfaces, the IEEE modified text within the latest 802.3cg draft. It now includes the following statement: “Connectors meeting the requirements of IEC 63171-1 (CD) may be used as the mechanical interface to the balanced cabling for M1I1C1E1 environments. The plug connector is used on the balanced cabling and the MDI connector on the PHY.”
Because the standard is still in draft, it is subject to change.

Pro-level AV-over-IP platform
Extron recently introduced the NAV Series AV-over-IP platform, which the company characterizes as a “no-compromise,” professional-level technology set. The NAV Series distributes and switches ultra-low-latency video, audio, and USB 2.0 signals over Ethernet networks. When introducing the platform in September, Extron explained that using its patented PURE3 codec, NAV delivers “visually lossless video over IP at resolutions up to 4K at 60 Hz with 4:4:4 chroma sampling.”
“A true-color [4:4:4] video signal includes all of the red, green, and blue color information of each pixel,” according to ClearOne.
Extron continued, “PURE3’s Intelligent Selective Streaming leverages low motion content to achieve extremely low bitrates while maintaining visually lossless performance. Most codecs make compromises in either image quality, bandwidth requirements, or latency … The NAV Series is the only streaming solution that offers both 1-Gbit/sec and 10-Gbit/sec encoders and decoders with compatibility across both systems. NAV can also deploy as a high-performance IP-based video and audio matrix, combining the flexibility of an IP-based system with the integration-friendly video and audio switching features found in conventional Extron matrix switchers.”
Casey Hall, Extron’s vice president of worldwide sales and marketing, commented, “Our new NAV platform was purpose-built for the professional AV integrator, offering uncompromised quality and flexibility that works in virtually any environment. NAV empowers AV integrators to create mixed 1-Gbit/sec and 10-Gbit/sec pro AV-over-IP applications that address a broader range of environments, delivering high-quality content with virtually no latency.”
The NAV Series includes the NAVigator System Manager, which provides an interface for centralized management, configuration, and control of Extron’s NAV systems. “NAVigator facilitates easy setup and configuration, and offers extensive features for monitoring, diagnostics, and troubleshooting,” Extron said. “NAV encoders and decoders support analog audio, embedded digital HDMI audio, and AES67 audio-over-IP, facilitating integration with DMP 128 Plus audio DSPs or other IP-enabled audio components.”
Several flavors of AV-over-IP technology exist, including HDBase-T-IP and SDVoE (Software-Defined Video over Ethernet). Many believe that SDVoE will see significant adoption; as it is adopted, it consumes market share currently enjoyed by technologies like matrix switches and KVM switches.
