In addition to their excellent isolation and insertion loss metrics, the GK-PMFWDM Series provides superior return loss, with a minimum value of 50 dB, which is crucial for preventing signal reflections that can adversely affect performance. The polarization-dependent loss is remarkably low at a typical value of 0.005 dB, preserving the quality and integrity of the transmitted signal across varying polarization states.
These multiplexers are built to handle high optical power levels, with a continuous wave power rating of up to 300 mW. They also offer excellent thermal stability, functioning reliably across a wide temperature range from -5°C to +70°C. The high tensile load capacity of 5 N further enhances their durability in various installation environments. The series supports a range of fiber types and provides flexibility in connector and fiber jacket options, making it an adaptable choice for diverse optical applications, including telecommunications networks, high-speed WDM systems, and sophisticated fiber optical instruments.
With their advanced design and robust performance characteristics, the GK-PMFWDM Series ensures that your optical systems operate at peak efficiency and reliability, even in the most demanding conditions.

Frequently Asked Questions
The GK-PMFWDM Series operates with a pass band wavelength range of 1950 to 2050 nm and a reflection band wavelength range of 1560 to 1580 nm. This range allows for effective wavelength division multiplexing across these critical optical communication bands.
The typical insertion loss for the GK-PMFWDM Series is 0.6 dB. This low insertion loss ensures minimal signal attenuation as light passes through the multiplexer, contributing to high-efficiency signal routing and combining.
The maximum insertion loss for this multiplexer is 0.8 dB. This value represents the worst-case scenario for signal attenuation within the device, ensuring that even under less ideal conditions, the signal remains effectively managed.
The device provides a typical isolation of 30 dB. This high level of isolation helps to prevent cross-talk and interference between channels, ensuring that signals are kept separate and their integrity is maintained.
The minimum isolation level for the GK-PMFWDM Series is 25 dB. This ensures that even at the lower end of performance, the device provides substantial separation between channels to minimize signal leakage and interference.
The minimum return loss is 50 dB. This high return loss indicates that the multiplexer effectively reflects back any light that is not transmitted, reducing potential signal loss and ensuring efficient operation in high-speed network systems.
The typical polarization dependent loss (PDL) is 0.005 dB. This very low PDL value signifies that the multiplexer maintains its performance regardless of the polarization state of the incoming light, which is critical for maintaining signal quality in polarization-sensitive applications.
The device can handle a maximum optical power of 300 mW (continuous wave). This capability allows the multiplexer to be used in high-power applications without compromising performance or risking damage to the device.
