MAP-200 Multiport Tunable Filter Module (mTFX-C1)

The Multiple Application Platform (MAP-200) multiport tunable filter module (mTFX-C1) dramatically simplifies test signal management for next-generation 100 G+ interfaces, sub-systems, and system test.


The mTFX-C1 is a modular Ethernet or GPIB instrument and can be directly managed from your PC-based automation system. It eliminates the need to re-purpose optical network technology or use complex libraries with specialized interface cards.

Based on next-generation liquid crystal on silicon (LCOS) technology, the mTFX-C1 is much more than a tunable filter. It combines variable attenuator, switch, power meter, and DWDM multiplexer functions to dramatically simplify photonic testing of coherent interfaces, amplifier, and DWDM systems. Leveraging TrueFlex™ technology, filters are continuously tunable in center wavelength and bandwidth and are not locked to the ITU grid. Multiple parallel wavelength paths can be created without disrupting already established connections—all with sub-GHz resolution. Industry-leading specifications for loss and out-of-band rejection ensure minimal impairments on your test signals.

Using the mTFX-C1, get the right wavelengths to the right test port with the right power—quickly – and flexibly isolate, groom, manage, and route any wavelength or group of wavelengths with a simple, intuitive GUI and/or SCPI-based remote commands.
