Video Transport over DWDM

PacketLight’s DWDM/OTN muxponders and transponders reduce the fiber needed for native SDI video and IP data transport applications between remote sites, cutting infrastructure costs and enabling carriers to add video services on top of their existing OTN metro or long haul backbone infrastructure.

One of the main challenges of the broadcast market is transporting multiple SDI native video streams in real-time between different media centers, for broadcasting live events and processing sites and satellite locations effectively. PacketLight’s optical fiber transport solution enables broadcasters to share the same fiber or OTN infrastructure in the same way as other common telecommunication protocols such as Ethernet, SONET/SDH and Fibre Channel.

Additional SD/HD/3G-SDI video requirements include copper-based or optical interfaces, pathological pattern encoding schemes, and support for different video rates, all of which are supported by PacketLight solutions.

PacketLight’s muxponder and transponder devices support a number of video interfaces such as, SD-SDI, HD-SDI, 3G-SDI and DVB-ASI, as a common part of the optical and fiber network solution, seamlessly integrating without the need for external converters. The solutions enable broadcast companies and carriers to utilize existing optical transport network and/or dark fiber for cost-effective, managed video transport.

PacketLight's solutions have an integrated network management module which provides full monitoring and control (through third party SNMP, web-based GUI or NMS), alarms and other diagnostic capabilities.

20G Muxponder Video Solutions

PacketLight’s 20G OTN ADM Muxponder (PL-2000) is effective, low cost, and easy to operate in today’s multi-rate, multi-protocol optical transport networks. The muxponders provide an efficient and flexible aggregation layer of multi-protocol/multi-rate sub-10G services into a common optical transport layer using 2x10G OTU2 uplink trunks, reducing the number of wavelengths.

The carrier grade 20G OTN ADM Muxponder is a high density, high spectral efficiency device that maps up to 16 multi-rate, bi-directional video copper SFP interfaces into an aggregated 2x10G OTU2 ITU G.709 standard-based uplink.

Supported services include:

• 3G HD-SDI, HD-SDI, SD-SDI, DVB-ASI
• FE/GbE
• 1/2/4G FC/FICON
• SONET/SDH: OC-3/STM-1, OC-12/STM-4, OC-48/STM-16

With this aggregation method, the muxponder increases each wavelength capacity and maximizes fiber usage, which translates to fewer colored optics, fewer optical filters and reduced network management and maintenance complexities and cost.

The OTU2 standard uplink enables the connection of the PL-2000 to any carrier OTU2 gray service or as alien wavelength over existing DWDM/OTN infrastructure.

200G Muxponder Video Solutions

PacketLight’s 200G Single Wavelength Muxponder (PL-2000M) enables high throughput of 200G per wavelength, and supports a mix of 4K IP video together with SDI video. This solution facilitates the combination of legacy and IP video transport over DWDM and OTN networks.

The carrier grade PL-2000M supports encryption and a mix of service, providing an efficient and flexible aggregation layer of multi-protocol/multi-rate 10G, 40G and 100G services into a common optical transport layer using a 200G OTN uplink trunk, reducing the number of wavelengths for meeting capacity growth needs.

Supported services include:

• 12G-SDI
• 10/40/100GbE
• 8/16/32G Fibre Channel
• OC-192/STM-64 SONET/SDH
• OTU2/OTU2e/OTU3/OTU4 OTN

With this aggregation method, the muxponder increases each wavelength capacity and maximizes fiber usage, which translates to fewer colored optics, fewer optical filters and reduced network management and maintenance complexities and cost.

The PL-2000M can operate together with the PL-2000 OTU2 uplink to aggregate SDI baseband video interfaces.

Video Interfaces and Features

PacketLight's video interface is a small form factor, pluggable, copper SFP that is plugged directly into either the PL-2000 muxponder or PL-1000TE transponder client port. The video SFP module provides an extremely small footprint O2E (optical-to-electrical) and E2O (electrical-2-optical) conversion without the need to support multiple, external bulky converters with their own power source.

Each video interface supports the commonly used DVB/SDI signals up to 2.97Gbps with embedded re-clockers, cable drivers, equalizers and monitoring capabilities.

Solution maintenance and spare parts are minimal as the pluggable SFP module that supports Tx and Rx covers the entire spectrum of video rates, through auto detecting the video rate and user configuration.
