PacketLight says it has enhanced support for video interfaces in both of its Optical Transport Network (OTN) and transponder-based offerings. The new feature is designed to enable efficient and simple streaming of high-capacity video for broadcast media companies and digital studios over fiber and standards-based OTN networks.
Different copper interfaces for video such as SD-SDI, HD-SDI, 3G-SDI and DVB-ASI are all supported by PacketLight's CWDM/DWDM and OTN product family. Additionally, video signals can be mixed with other data and storage traffic such as 1G/10G Ethernet and 1/2/4/8/10G Fibre Channel.
Use of the PacketLight platforms reduces the number of fibers needed for video and data transport between sites, thus reducing the infrastructure costs as well as enabling carriers to add video services on top of their existing OTN metro or long-distance backbone infrastructure.
PacketLight says its modular approach offers optical-to-electrical and electrical-to-optical conversion in a small footprint, without the need of bulky converters. The platforms also offer SNMP-based monitoring and control management software for the conversion process. The systems can map up to 16 multirate bidirectional video services such as DVB-ASI, SD-SDI, or HD-SDI into aggregated 10G or 20G OTU2 within its 1U carrier grade PL-2000 product, for example.
In addition, PacketLight's product line also supports SFP-based pluggable client video interface modules for the commonly used DVB/SDI signals of up to 2.97-Gbps with embedded re-clockers, cable drivers, equalizers, and monitoring capabilities.
