1550 nm, 40 GHz Analog Modulator, PM Output, V Connectors (IML-1550-40-PM-V)

Data Sheet

Product Overview

The Optilab IML-1550-40-PM-V Intensity Modulator is designed for analog modulation of up to 40 GHz for microwave links, antenna remoting, and RF over Fiber. It is a high linearity, low driving voltage lithium niobate mach zehnder interferometer (MZI) design. It is a bias-stabilized lithium modulator that proves to be extremely stable for long periods of time, and features excellent stability in a biased circuit, operating from 1525 nm to 1610 nm. It has an excellent operating temperature tolerance ranging from -30 ºC to +60 ºC, and its low insertion loss provides for its maximum transmission power. The IML-1550-40-PM-V uses a Polarization Maintaining (PM) input and output fiber, and features separate RF and bias ports.
