Ascentta Tunable 1x2 Optical Coupler (1270, 1310, 1450, 1550, 1650nm)
Description
The MTTC Series Mechanically Tunable Coupler (1x2) from Ascentta offers precise manual control over optical signal splitting, enabling real-time tuning of insertion loss between 0 to 40 dB. Available at key telecom wavelengths including 1270, 1310, 1450, 1550, and 1650 nm, this coupler is ideal for a wide range of optical network applications, lab environments, and fiber optic instrumentation requiring configurable performance.
Designed with minimal excess loss (typical 0.3 dB) and low polarization-dependent loss (PDL ≤ 0.15 dB at 3 dB split), the MTTC series ensures superior signal integrity. It supports optical power handling up to 300 mW, and its compact and rugged 50×45×87 mm form factor enables easy integration into standard systems.
Each device is customizable in terms of fiber type, cable structure, pigtail length, and connector configuration. With a broad operating temperature range of -20°C to +70°C and high directivity (≥55 dB), the MTTC Series is built for both performance and durability in demanding environments.
For custom configurations, Ascentta offers tailored solutions to meet your specific application requirements.

Frequently Asked Questions
A mechanically tunable optical coupler allows manual adjustment of the power split ratio between two output ports. By tuning the insertion loss between 0 and 40 dB, users can precisely control signal distribution in optical systems, making it ideal for testing, balancing, and prototyping applications.
The MTTC Series supports several telecom and sensing wavelengths, including 1270 nm, 1310 nm, 1450 nm, 1550 nm, and 1650 nm. Custom wavelengths can also be requested to suit specific application requirements.
The MTTC coupler can safely handle up to 300 mW of continuous optical power, making it suitable for both standard and moderately high-power fiber optic applications.
The MTTC Series is fully customizable. Users can choose from various connector types (FC/APC, SC/PC, LC/UPC, etc.), fiber types (SMF, PMF), and cable jackets (250 µm bare fiber, 900 µm tight buffer, 2 mm or 3 mm jacketed).
Yes. With an operating temperature range of -20°C to +70°C and storage tolerance from -40°C to +85°C, the MTTC Series is built for reliable performance even in demanding environments.
