Finisar Introduces Complete XFP-RF Pluggable Optical Transmitter Portfolio for Cable Access Networks

Today we announced the latest product to join our optical transmitter portfolio for cable access networks. Read today’s press release.

We will demonstrate our portfolio of XFP-RF transmitters this week at the SCTE Cable-Tec Expo in Atlanta, Georgia, October 22-24 in booth #403.

If you happen to be at the show, come on by and say hello.

Finisar Tunes Up the SCTE Expo Trade Show

This week’s blog post comes from Shawn Esser, Director of Product Marketing for CATV Products at Finisar.

Last week Finisar demonstrated the industry’s first 1 GHz RF-modulated, widely-tunable optical transmitter in a Small-Form Factor module at the Cable Tec-Expo trade show in Orlando, Fla. The Cable-Tec Expo, organized by the Society of Cable Telecommunications Engineers (SCTE), is the cable industry’s engineering show of the year and drew about 9,200 people. The active demonstration of wavelength-tunability showed a new tool for cable operators to route video and data services in the cable access network. The demonstration included two televisions, two different movie streams, and two wavelength-tunable XFP-RF transmitters. Using Dense Wavelength Division Multiplexing (DWDM), the video content showing on the televisions was swapped by changing the wavelengths of the transmitters. Customers saw how bandwidth, and thus services, could be dynamically increased to serving areas that have high contention with this new wavelength-tunable capability.

The product was very well-received by visitors to Finisar’s booth. Visitors were also impressed that Finisar’s XFP-RF transmitter is the first 1GHz RF-modulated optical transmitter packaged in a Small Form Factor pluggable optical module. The XFP module is commonly used in 10Gb/s digital applications today. Finisar combined its high-volume Small-Form Factor module capabilities and its extensive experience in CATV optics to significantly reduce space and energy of transmitters for cable access networks. The XFP-RF transmitter can be designed into existing broadband optical platforms today to double the density and halve the power consumption of transmitters in Hybrid Fiber Coaxial (HFC) networks. It can also be plugged directly into next-generation infrastructure equipment, such as Converged Cable Access Platforms (CCAP) currently under development, to further reduce costs for cable operators.

Finisar was also displaying its Small-Form Factor Pluggable ONU (EPON Stick) that converts standard GE media convertor into EPON Optical Network Unit replacing the need for a standalone ONU. This enables MSOs to use the same premise equipment with a pluggable port (SFP) that they use to deploy business services over point to point Ethernet and WDM to be used over EPON. Mike Holmes, Finisar Director, presented DPOE DAC (Demarc Auto-Configuration) along with Kevin Noll of Time Warner Cable, Curtis Knittle of Cable Labs and moderator Rammy Bahalul of Omnitron. Their presentation explained the DPOE DAC benefits highlighting the EPON Stick, Demarc features and the successful Time Warner Cable DAC testing.

Finisar at the 2012 Satellite Conference and Expo

This week’s blog post comes from Shawn Esser, Finisar Product Line Manager.

Come see us this week at the Satellite Conference and Expo in Washington, D.C., as we showcase our RF-over-Fiber products at Finisar booth #1209.

Serving the military/government, commercial, broadcast, mobility, and telecommunications industries, the Satellite show is for anyone involved in the satellite-enabled communications industry.

Finisar continues to innovate in RF-over-Fiber technology to provide customers with solutions using fiber optics. We offer a range of custom products that provide transmission solutions for distribution, broadcast and fiber-to-the-home (FTTH) applications. In short, our products make the delivery of broadband services to the home possible.

At this year’s conference, we’ll be joined by more than 10,000 satellite professionals coming together to discuss best practices, experience the newest technology and collaborate with colleagues from all sectors of the satellite community.

To check out what we did at last year’s show, see Finisar displays RF-over-Fiber solutions at Satellite 2011.

We hope to see you at the show.

Finisar displays RF-over-Fiber solutions at Satellite 2011

Shawn Esser, Finisar PLM This week’s post comes from guest blogger, Shawn Esser, Finisar Product Line Manager.

Finisar exhibited its Analog RF-over-Fiber products last week at the SATELLITE 2011 conference in downtown Washington D.C. The SATELLITE 2011 conference focused on opportunities in military, broadcast, enterprise, mobile, Telco and commercial satellite applications. Reportedly, 10,000 satellite professionals gathered to learn the best practices, experience the newest technology and collaborate with colleagues from all sectors of the satellite community.

Most of the visitors to the Finisar booth were either from the commercial or military industries. A majority of them were from the U.S. but there was also international representation from Europe, Asia and Latin America. Finisar was displaying optical products operating in several RF frequency ranges: from the common L-band (2 GHz) up to the Ka-band (40 GHz). The products are available in various form-factors: small transmitter and receiver optical modules that customers integrate into their systems, and complete subsystems in rack-mount equipment and outdoor enclosures.

You may wonder: how does Finisar, a leader in optical communications, play in the satellite industry?

Usually satellite and fiber optics are seen as competing technologies in our industry. But Finisar fiber optic technology allows customers in the satellite industry to deploy “remote” ground antennas: the antennas are located remotely away from the facilities that house the down-conversion and processing equipment for video, communication and data content from satellites. Traditionally, these facilities had to be located close to the antennas because the high-frequency RF signals could only travel short-distances (i.e. less than 500 feet) over copper coaxial cables. This would mean that these buildings could be in inconvenient locations such as mountain sides or very rural areas at a significant expense. Using RF-over-Fiber, an optical transmitter is located at the antenna in a small outdoor enclosure which converts the satellite signals in native format to optics. This can then be transported long distances over optical fiber, typically less than 10 km but the distance could be 100 km or longer. At the processing facility, an RF-over-Fiber receiver converts the optical signal back to RF on a copper coaxial cable. This allows a central facility to service multiple satellite ground antennas to reduce buildings, technicians and equipment. Using fiber optics also protects expensive processing equipment from lightning strikes on the ground antennas.

There are also applications for RF-over-Fiber solutions on ships and aircraft to replace copper coaxial cables to reduce weight and eliminate issues with RF interference when using cable.

Finisar continues to innovate in RF-over-Fiber technology to provide customers with more cost-effective and higher-performing solutions using fiber optics.
