The High Definition Serial Digital Interface (HD-SDI) is standardized in SMPTE 292M and provides a nominal data rate of 1.485 Gbps. For transmission distances greater than 100 meters, copper is not sufficient and fiber is required. Video formats supported are 720p and 1080i. Full 1080p 50/60 Hz formatting is supported by SMPTE 424M. SMPTE 424M is also commonly referred to as 3G-HD.
Uncompressed HD-SDI Video Over Fiber
Optiva® SMPTE 292M and 424M compliant transmission links are the perfect solution for transmitting the full range of SMPTE HD resolutions over long or short distances with a single wavelength. This single fiber, single wavelength solution is perfect for any professional broadcast application, whether in a fixed Production facility or mobile O/B facility. HD-SDI currently enjoys widespread acceptance. The requirement to preserve full 1080p throughout the entire production and post-production process is driving the future migration to 3G-HD. The desire to produce high definition content at 12-bit color depths and to provide support for R’G’B’ and 4:4:4:4 processing, is also driving these higher bandwidth requirements.
Another unique capability of this system is that it utilizes Optiva's patent-pending Daisy Chain™ Technology. This gives system designers the flexibility to add additional Optiva insert cards, for the purpose of transporting additional video, audio, and/or data signals over the same fiber.
System Design
Switching and multicasting the various configurations of OTP-1HDP and OTP-1HD (as well as all other Optiva signal cards) over the OptiLinx® Switching Platform is straightforward, making this the perfect solution for reconfigurable systems with many sources of high definition broadcast video, and many downstream destinations in the broadcast workflow process.
Optiva® insert cards are supported by both 19” rack mount and compact tabletop or wall mountable enclosures. The 3RU 19” rack mount enclosure (Model: OT-CC-16-100) can support up to 16 insert cards plus dual-redundant hot-swappable power supplies (Model: OT-CC-16-100-RPS). Also available in the 19” rackmount form factor is the 4-slot (Model: OT-CC-4-1U) which houses 4 insert cards in 1RU of rack space. The compact one slot (Model: OT-DTCR-1) and two slot (Model: OT-DTCR-2) enclosures are useful for remotely deployed signals. The desktop enclosures require an external power supply (Model: PS-9012).
OptivaTM Upgrade Path
This system can be purchased without an optical port as an add-on to an existing Optiva
TM system daisy-chain. (See "Non-Optical Version").
