Frequently Asked Questions
The GK-PMTC Series coupler is designed to operate at a center wavelength of 2000 nm with an operating wavelength range of ±40 nm around this center wavelength.
The coupler offers a range of coupling ratios including 1%, 2%, 4%, 5%, 10%, 20%, and 50%. Custom ratios can be specified based on application requirements.
The maximum excess loss is 1.2 dB for 1 × 2 configurations and 1.5 dB for 2 × 2 configurations.
The coupler uses polarization maintaining (PM) fiber, specifically PM 1550 Panda fiber for input and output ports, and SMF-28 or PM 1550 Panda fiber for the tap port, to ensure that the polarization of the light is preserved throughout the splitting process.
The coupler operates within a temperature range of -5°C to +70°C and can be stored at temperatures from -40°C to +85°C.
The coupler can handle a maximum continuous wave optical power of 300 mW.
Yes, it is capable of withstanding peak power up to 5 kW for nanosecond pulses.
The coupler can be supplied with different fiber jackets including 250 μm Bare Fiber, 900 μm Loose Tube, or as specified by the customer.
The insertion loss (IL) increases by 0.3 dB, and the return loss (RL) decreases by 5 dB for each connector added. The extinction ratio (ER) may also be reduced by 2 dB with additional connectors.
The connector key alignment is aligned to the slow axis of the polarization maintaining fiber to ensure proper polarization control and optimal performance.
