More choice to photonic switch range
Polatis is broadening its product portfolio to include smaller scale optical switches.
Expansion for optical switch portfolio
Polatis has made a major expansion of product range as previewed at the recent OFC/NFOEC conference in Anaheim, California.
Through its all-optical nature, Trinity expands the capabilities of today's broadcast infrastructure to meet the needs of existing and future broadcast standards.
While the vast majority of audio and video transport signals are carried over copper today, distances are limited to only 50-100m for transporting new high definition standards such as 1080p.
Transport by optical fibre permits far greater distances without amplifying and re-clocking.

The SD138-11-31-211 silicon PIN photodiode sandwich detector from Advanced Photonix features two silicon PIN photodiodes vertically integrated in a hermetic TO-5 package.
All-optical switching enables the signal to be routed with universal interfaces capable of handling virtually any audio and video signal, whether analogue or digital.
The Trinity series is designed specifically for the video transport and broadcast market.
It supports virtually all protocols and feed rates - AES, SMPTE-276M, 259M and 292M, ASI/DVB, NTSC, Pal, QAM, and others.
Underpinning the Trinity design is Polatis' own beam-steering technology.
Unlike other photonic solutions, Trinity can establish and maintain connection routes without a signal present, in a preprovisioned "ready and waiting state".
Not relying on an optical signal feedback to maintain the connection also means no modulation is introduced to the signal, a feature valued by customers who use Polatis products for RF-over-fibre applications today.
Like all Polatis products, traffic can be bidirectional, and carry single or multiple wavelengths.
"We believe the timing is right for this product, as optical interfaces on video routers become more commonplace, and the bandwidth for contribution-quality high-definition signals naturally drives the infrastructure towards fibre", commented Aaron Bent, Polatis VP of Marketing.
"Optical switching can simply be viewed as a logical and flexible extension to the existing protocol layers in video routing".
"To ease implementation, we've designed Trinity to integrate seamlessly with the existing routing infrastructure".
"It supports the popular SMS-7000 Native Protocol for control, and even supports familiar strategies like global tie-line management".
Trinity is the highest performing product in its class, with optical losses less than 1dB for its 16 x 16 product.
Polatis is immediately introducing two products, a 1RU product, managing up to a total of 32 fibre interfaces, and a 3RU product, managing up to a total of 64 fibre interfaces.
As part of several new product introductions, Polatis has planned the worldwide unveiling of Trinity as part of this year's OFC/NFOEC 2006 tradeshow in Anaheim, California.
At the show, Polatis will integrate its Trinity product into an end-to-end video network to demonstrate optical switching of uncompressed video signals.
The live product demonstrations will take place on Booth 1940, during exhibition hours.
