SANTEC's MTF is a single channel, world smallest Micro Electro Mechanical Systems (MEMS) tunable filter (TF) for 400G+ digital coherent transceivers. The MTFis a superior passive optical component used in CFP and CFP2 form factor transceivers to reduce optically amplified noise and to improve transmission quality. The MTF has achieved a record low-voltage specification of 12V; 5 times lower when compared with other 60V suppliers. In addition, the MTF does not need a specific high voltage IC to drive the component.
