1550 nm, 20 GHz Intensity Modulator, PM Output (IM-1550-20-PM)

Data Sheet

The Optilab IM-1550-20-PM is a 20 GHz Intensity Modulator that is manufactured with both PM (Polarization Maintaining) fiber on input and output ports, incorporating a zero-chirp design for ultra long haul transmission.

Product Overview

The Optilab IM-1550-20-PM is a 20 GHz Intensity Modulator that is manufactured with both PM (Polarization Maintaining) fiber on input and output ports, incorporating a zero-chirp design for ultra long haul transmission. Covering full C-band and L-band, it can be used for any ITU grid DWDM channel, with exceptional E/O bandwidth and a highly linear transfer function. Applications include digital transmission up to 20 Gb/s, analog RFoF transmission to 20 GHz, optical pulse generation, mode-locked fiber laser and microwave optical link. The Optilab IM-1550-20-PM operates with low drive voltage, making it compatible with a wide variety of modulator drivers, and a separate bias port allows the modulator to operate at specific points of the transfer function. Supplied in a hermetic package, qualified to TelcordiaTM GR-468-CORE, this product assures high reliability and performance at all times. Contact Optilab for more information.
