Optametra’s hardware incorporates the OM3005 polarization-diverse Coherent Modulation Receiver (CMR), allowing simultaneous measurement of any modulation format, incorporating coherent dual-polarization (DP) QPSK, and subsets, like differential QPSK. The company’s software regulates and processes for the real-time burst-mode constellation diagram displays, eye-diagram displays, bit-error detection, polarization (Poincare sphere), and more. Bit rates to 43 Gb/s (40G DP-QPSK) are supported with simple 112 Gb/s (100G DP-QPSK) upgrades available mid-2009.
Optametra will introduce the new OM4005 and OM4006 at OFC/NFOEC 2009, San Diego Convention Center, California, Booth 2353 from March 23 to March 26, 2009.
The ability for the carriers to smoothly grow data rates without pulling the new fiber is the compelling value proposition of complex and polarization-diverse optical modulation. The carriers and network equipment producers have displayed 112 Gb/s transmission in an otherwise-10 Gb/s channel utilizing such modulation; conventional modulation leaves 90% of the fiber capacity unused.
This architectural transformation of the telecommunications is driven by growing demand for bandwidth by products like YouTube, data centers, and high-speed infrastructure build-out. Instead of pulling new fiber at more than $50k/km, modulation techniques with advanced spectral efficiency provide an easier, more flexible and lower-cost route to increasing network capacity.
Although the other tools for visualizing complex optical modulation have been launched in February 2009, “Optametra’s OM 4005 and OM 4006 Coherent Lightwave Signal Analyzers™ are the first available to measure and display the full optical field of coherent signals,” stated Rob Marsland, president of Optametra, “and they are by far the most cost-effective.”
Using intradyne and the new phase-estimation techniques, Optametra’s instruments present in-phase and the quadrature eye diagrams, constellations, data waveforms, and bit-error rates (BER) for both polarizations of light in fiber, utilizing either a customer’s standard network sources or available built-in tunable lasers optimized for coherent applications.
Pricing and Availability:
Optametra’s new OM4005 and OM4006 coherent lightwave signal analyzers have standard lead-times of 10 to 12 weeks ARO, depending on configuration and current availability. The pricing starts at $87,900 in the US. The company’s products support all four-channel 40 Gs/s or faster real-time oscilloscopes, incorporating those from Agilent, Tektronix, and LeCroy.
Optametra is a US-based developer of instrumentation that enables customers to develop, manufacture, install, and monitor complex modulation transceivers.
