Frequently Asked Questions

What wavelengths does this WDM support?

This Wavelength Division Multiplexer (WDM) supports the combination or separation of light at 635 nm and 1064 nm wavelengths. It is specifically designed to handle these two wavelengths to facilitate various applications in fiber optics and laser systems.

What is the typical insertion loss for this WDM?

The typical insertion loss is 0.2 dB at the 1064 nm wavelength and 1.0 dB at the 635 nm wavelength. This low insertion loss ensures minimal signal attenuation and efficient signal transmission through the device.

What is the maximum polarization dependent loss?

The maximum polarization dependent loss (PDL) is 0.1 dB. This low PDL indicates that the device performs consistently across different polarization states of the light, maintaining high performance in polarization-sensitive applications.

What is the minimum isolation provided by this WDM?

The minimum isolation provided is 20 dB. This high isolation level ensures that the WDM effectively separates the wavelengths, minimizing crosstalk and interference between the channels.

What is the thermal stability of this WDM?

The WDM exhibits a thermal stability of ≤ 0.002 dB/°C. This means the device maintains its performance with minimal variation in insertion loss as the temperature changes, making it suitable for environments with fluctuating temperatures.

What is the maximum optical power it can handle?

The device can handle up to 5 W of continuous wave optical power. This high-power handling capability makes it suitable for use in high-power laser systems and other demanding applications.

What is the minimum return loss for this WDM?

The minimum return loss is 55 dB. A high return loss indicates that the WDM effectively prevents the reflection of light back into the system, reducing potential signal degradation and improving overall system performance.

What is the operating temperature range?

The WDM operates within a temperature range of -40°C to +75°C. This wide operating temperature range allows the device to function reliably in various environmental conditions.

What is the storage temperature range?

The storage temperature range is -40°C to +85°C. This range indicates the temperatures within which the WDM can be stored without affecting its performance or integrity.

What fiber types are compatible with this WDM?

The WDM is compatible with Corning HI 1060, Nufern FUD-3584, and other fiber types as specified during the ordering process. Compatibility with these fiber types ensures flexibility in integration with different fiber optic systems.
