Superb Performance in 40-Gb/s Lightwave Systems
(631) 231-1700 x218
NY – January 13, 2009
– Narda Microwave-East, an L-3 Communications (NYSE: LLL) company, today announced
the FO-MDA-40-25G-1, a low-cost, high-performance lithium niobate modulator driver that delivers exceptional
performance in 300-pin MSA transponders employed in DPSK long-reach 40-Gb/s lightwave communication systems.
FO-MDA-40-25G-1 combines monolithic microwave integrated circuits
(MMICs) developed by Narda specifically for modulator driver applications along with proprietary fabrication
techniques. The result is a three-stage modulator driver that produces an exceptional eye pattern and has a 3-dB
bandwidth of 85 kHz to 40 GHz, gain of 29 dB, input and output return loss of 12 dB, RMS additive jitter of only
550 ps, rise and fall times (20 to 80%) of 10 ps, and output power up to 8 Vpp with an input voltage of 450 mVpp.
The FO-MDA-40-25G-1 operates at a maximum data rate of 43 Gb/s, features electronic eye-crossing control of 40% to
70%, and has variable amplitude from 0.5 to 8 Vpp. Power requirements include +3.3 VDC and +5.0 VDC, and operating
temperature range is from 0o to +70º C. The FO-MDA-40-25G-1 is housed in a package measuring only 1.1 x 1.1
x.34 in. and uses GPPO connectors.
The FO-MDA-40-25G-1 joins Narda's growing family of products for lightwave systems, including clock oscillators,
phase-locked oscillators, electro-absorptive and lithium niobate modulator driver amplifiers, and pulse carver
Engineering samples of the FO-MDA-40-25G-1 are now available, and production is scheduled for Q1 2009.
