SDL/JDSU 12Gb/s Mach-Zehnder (M-Z) modulators driver VM12EMD-418 ~ H301-1210

Description

Detailed specs available upon request.
12Gb/s drivers for M-Z light modulators
EMLs hese rugged, low-cost, high performance modulator-drivers utilize single-substrate COPLANAR MIC thin-film technology and state-of-art GaAs active devices. Systems using these drivers will achieve improved EYE opening, increased phase margin over time and temperature, higher extinction ratios, and lower BER. Useful to 20 Gb/s NRZ. A highly rectangular EYE is produced at rates to 12 Gb/s, and a sinusoidal EYE at 20 Gb/s. Designed to drive Mach-Zehnder external modulators from ECL/SCFL input levels, they feature (a) a built-in bias terminal, (b) an EYE symmetry adjust terminal, (c) a “digitized” output for very high extinction ratios even when the input data is relatively “dirty”, (d) constant output over temperature and Vin, and (e) well-matched input and output impedances. The output, though “saturated”, is electrically adjustable over a wide range. Typical output rise and fall times at nominal input and output approach 20ps. Pulse parameters such as rise and fall times and EYE opening at 10 Gb/s are guaranteed. Supplied with solderable contact pins for DC and removable SMA-F RF connectors.
