1550 nm, 20 GHz Compact Intensity Modulator (IMC-1550-20)

Data Sheet

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 20 GHz for satellite links, antennae remoting, and RF over Fiber.

Product Overview

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 20 GHz for satellite links, antennae 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 +70 ºC, and superior insertion loss provides for its maximum transmission power. The IMC-1550-20 uses a Polarization Maintaining (PM) input and Single Mode (SM) output fiber, and features separate RF and bias ports. Contact Optilab for more information.
