1550 nm, 20 GHz Low Drive Compact Intensity Modulator

VENDOR : optilab


The Optilab IMC-1550-20 Intensity Modulator is designed for TDM and WDM up to 25 Gb/s transmission and can also be incorporated for analog modulation of up to 15 GHz for satellite links, antenna remoting, and RF over Fiber. It is a hands-on bias-stabilized 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, low drive voltage requirements, and superior insertion loss provides for its maximum transmission power. The IMC-1550-20 uses a Polarization Maintaining (PM) input fiber and a Single Mode (SM) output fiber. It features separate RF and bias ports, GPO connector for RF input and three lead pins for bias input, built in PD for bias monitoring, and photodiode (Anode and Cathode). Contact Optilab for more information.
