Narda Introduces 40 Gb/s Modulator Driver
Narda Microwave-East, an L-3 Communications company, announced the FO-MDA-40-15D-1, a low cost, high performance EML driver for 40-Gb/s lightwave communication systems.
The FO-MDA-40-15D-1 joins Narda's growing family of products for lightwave systems, including clock oscillators, phase-locked oscillators, lithium niobate and electro-absorptive modulator driver amplifiers and pulse carver drivers. The FO-MDA-40-15D-1 is optimized for VSR 300-pin MSA SFF transponders. It offers dual inputs that mate directly with standard multiplexers. It operates at a maximum data rate of 44 Gb/s, features electronic eye-crossing control of 40 to 70 percent, and has variable output between 2.5 and 3.4 Vpp. The driver has a 3 dB bandwidth of 35 GHz and gain at 20 GHz of 23 dB. RMS additive jitter is typically 0.55 ps, and 20 to 80 percent rise and fall time is 10 ps. The unit measures 25.32 x 29.46 x 6.35 mm and uses GPPO connectors.
