Compact Optical Tunable Filter
MTF-FT
- Compact size: 7.5 × 5.5 × 3.5 mm (W×D×H)
- Flat-top frequency response with optimized Gaussian order
- Minimum fiber bend radius: 5 mm
- 17V low voltage operation

Overview
MTF-FT is an optical filter that uses patented technology based on Santec’s unique optical design, and combines flat transmission characteristics in the signal band with steep noise rejection performance.
By effectively blocking adjacent noise while suppressing signal distortion, it significantly improves signal quality in high-speed, large-capacity communications, achieving optimal performance for next-generation optical transceivers exceeding 800 Gb/s.
Furthermore, the module supports industry-standard SFF (Small Form Factor) transceivers such as QSFP-DD and CFP2-DCO, and with the industry’s smallest size class of 7.5 × 5.5 × 3.5 mm and low-voltage operation, it can meet strict requirements for miniaturization and low power consumption.
-

Compact size
It offers many advantages, including high-density mounting, low power consumption, and improved design freedom.
-

Flat passband with steep noise rejection performance
By suppressing signal distortion while sharply blocking adjacent noise, it achieves both high communications quality and channel density.
-

Telcordia GR-468 compliant
It can be safely installed for a long time in communication infrastructure that requires high reliability and durability.
-

RoHS-compliant
It is environmentally friendly, RoHS-compliant, limits the use of harmful substances, and supports sustainable product creation.
