Fiber Optic WDM

Dual wavelength combiner/splitter (WDM)

Based on thin filter technology, it provides the ability to combine two laser wavelengths that are far apart into a single fiber output. The merged wavelengths can be specified by the customer and are at least 200nm apart. This device has the potential to combine wavelengths ranging from 400 to 2000 nanometers across the entire range.

Multi wavelength combiner/splitter (WDM)

Based on volume grating technology, several close laser wavelengths can be combined into a single fiber output. The wavelength for merging can be specified by the customer, and the distance between them can be close to 10nm. The number of merged wavelength channels can also be specified. This device has the potential to combine wavelengths ranging from 400 to 2000 nanometers across the entire range.

DWDM filter (FBG only)

Xiaoxiao Photon's DWDM FBG fiber Bragg grating filter has attracted more attention due to its flat top and steep spectral slope. Using our unique toe mask technology and FBG writing technology, we have fabricated DWDM fiber grating filters with an isolation greater than 40 dB and a reflection bandwidth of -25 dB. The reflection bandwidths are less than 1 nm (100 GHz), 0.5 nm (50 GHz), 0.25 nm (25 GHz), 0.13 nm (12.5 GHz), and 0.06 nm (6.25 GHz), respectively.

DWDM add/drop module (FBG with simulator)

Xiaoxiao Photon's single channel DWDM FBG add/drop module is based on advanced fiber Bragg grating (FBG) filtering technology and has three ports for multiplexing or demultiplexing. One of the main advantages of this device is the flexibility of channel wavelength selection, which can be any wavelength specified within the S, C, and L band ranges. This device can be used to add or remove any single channel wavelength from an array of multiple wavelengths. The channel spacing can be selected from 6.25Ghz, 12.5Ghz, 25Ghz, 50Ghz, 100Ghz, and 200Ghz.

DWDM multiplexer (multi-channel, splitter multiplexer)

Xiaoxiao Photon's multi-channel DWDM FBG wavelength division multiplexer is based on our advanced fiber Bragg grating (FBG) filtering technology and has multiple ports for multiplexing or demultiplexing. The maximum number of available channels is 8, and the configuration on the port is 1x9. One of the advantages of this device is the flexibility to choose the number of channels and wavelengths, which can be any one within the ITU grid or customer specified S, C, and L band ranges. This device can simultaneously achieve multiplexing or demultiplexing of 2 to 8 channels. The channel spacing can be selected within the range of 6.25 GHz, 12.5 GHz, 25 GHz, 50 GHz, 100 GHz, and 200 GHz.

Fiber optic wavelength division multiplexer (visible light)

Xiaoxiao Photon's wavelength division multiplexer (WDM) is used to mix or split two beams of light with different wavelengths. We offer a variety of wavelength division multiplexers, whose wavelength combinations span the visible, near-infrared, and infrared spectra. Our visible light wavelength division multiplexers are also known as "wavelength combiners" because they are commonly used in microscopy applications to generate multi-color composite images.
