976/1064 nm Singlemode Wavelength Division Multiplexers (GK-PMWDM Series)

Single mode wavelength division multiplexer (WDM) is a passive device used in optical communication systems to combine or separate light of different wavelengths. These devices are very important in optical networks because they allow multi wavelength signals to be transmitted simultaneously in the same fiber, significantly improving the bandwidth utilization of the fiber. The following are some key characteristics and applications of single-mode wavelength division multiplexer:

Low insertion loss: Single mode wavelength division multiplexer has obvious low insertion loss characteristics, which means that the signal loss is minimal when passing through the device. For example, the maximum insertion loss of certain devices is 0.35dB.

Low polarization dependence: These wavelength division multiplexers are designed to be insensitive to changes in the polarization state of light, ensuring signal stability and reliability.

High isolation: Single mode wavelength division multiplexer can provide high isolation, typically with a minimum isolation of 13dB.

This helps prevent interference between signals of different wavelengths.

Excellent environmental stability: These devices are capable of stable operation over a wide temperature range, such as from -5 ° C to+70 ° C.

This makes them suitable for various environmental conditions.

High Return Loss: Single mode wavelength division multiplexers typically have high return loss, with a minimum value of 60dB.

This helps reduce reflections and improve signal quality.

Wide wavelength coverage: They can cover a wide wavelength range from 488 nm to 2000 nm.

Make it suitable for multiple different communication windows.

Customized services: Many manufacturers offer customized services that allow customers to customize wavelength combinations, bandwidths, fiber lengths, and connector types based on specific needs.

Widely used: Single mode wavelength division multiplexer has a wide range of applications in EDFA (erbium-doped fiber amplifier), CATV (cable television), WDM (wavelength division multiplexing) networks and fiber optic instruments.

High power processing capability: These devices are capable of processing up to 300 mW of continuous optical power.

Make it suitable for high-power applications.

Multiple configurations: Single mode wavelength division multiplexer has multiple configurations, such as 1 × 2 and 2 × 2, to meet different network architecture requirements.

These characteristics make single-mode wavelength division multiplexers an indispensable component in modern optical communication systems, supporting high-speed data transmission and network expansion by improving the transmission efficiency and flexibility of optical fibers.
