Finisar, a provider of fiber optic solutions for high-speed networks, has added four new 1310nm optical components to its technology suite.

 

The new optical components are specifically designed for satellite and community antenna television (CATV) broadcast equipment and modules. They meet the stringent specifications of high-speed video applications such as the emerging SMPTE 424ME standard for 3 Gbps SDI (3G-SDI) data transmission.

 

The new devices from Finisar consist of Fabry-Perot lasers (FP) and distributed feedback laser (DFB lasers), and PIN or PIN+TIA (News - Alert) receivers. The new 1310nm components are: FP-1310-5I-50SMF-xx FP laser, DFB-1310-4I-50SMF-xx DFB lasers, PIN-1310-50SMF-xx PIN photodiodes, and a PIN-1310-2I-LC PIN+TIA receiver.

 

Each of the components comes with electrical flex circuit or pin interface options, as well as pigtails that can be customized in length and connector type. The PIN-1310-2I-LC PIN+TIA receiver is designed to be paired with Finisar's FP-1310-5I-LCA.

 

The new optical devices offer many advantages. They simplify video equipment development by preserving signal integrity across links. This will enable engineers to gain more margins and therefore greater flexibility in focusing their design resources, resulting in faster time-to-market.

 

The pigtailed and bulkhead mounted versions of 1310nm components give engineers multiple options in designing broadcast equipment. Moreover, low-cost internal manufacturing capabilities enable the company to offer these components with competitive pricing.

 

“Part of the challenge in designing equipment to 3G-SDI is maintaining a significant jitter injection margin,” Finisar said. “Analog modulation is required for video applications and is a potential source of loss resulting in reduced video quality. The new 1310nm components are built with Finisar's patented laser and optical assembly technologies, and are designed to withstand the test matrixes called out in the 3G-SDI standard.”

 

“Video applications are vulnerable to quality degradation unless sufficient signal integrity margin is maintained,” said Jim Tatum, director of marketing at Finisar's Advanced Optical Components. “Finisar's proven optical technology will help establish its presence in the high-speed video market by enabling its customers to exceed SMPTE 424ME specifications.”

 

The four 1310nm optical components are being sampled now, and will be available in volume production by Q4 2008, the company said.
