1550 nm, 40 GHz Compact Intensity Modulator, GPPO Connectors (IML-1550-40-G)

Data Sheet

Product Overview

The Optilab IML-1550-40-G Intensity Modulator is designed for analog modulation of up to 40 GHz for satellite links, antenna remoting, and RF over Fiber. It is an ultra low drive voltage lithium modulator with excellent stability in a biased circuit, operating from 1530 nm to 1610 nm. It has an operating temperature tolerance ranging from -30 ºC to +60 ºC. With low insertion loss, and ultra low RF drive voltage, IML-1550-40-G provides optical transmission performance for analog modulation system. The IML-1550-40-G features a GPPO
connector for RF input and three lead pins for bias input, built in PD for bias monitoring, and photodiode (Anode and Cathode).
