HYC's AWG CWDM4 module is based on silicon chip technology, offering deep wavelength isolation, compact structure, and excellent reliability. It can replace TFF (thin-film filter) type CWDM and is widely used in 40G and 100G high-speed optical modules for optical signal multiplexing and demultiplexing, such as QSFP+ and QSFP28.

Wavelength Range (nm): 1290-1350, 1470-1610 Operating Temperature (°C): -10 to 70 Insertion Loss (Mux) (dB): ≤1.4 (4ch), ≤2.6 (8ch)

The Metro-X CWDM Mux/Demux Filter is based on dielectric thin-film technology, designed for integration in low-cost Metro and Access networks. It supports applications such as fiber to the home, business, or curb, enabling 4 or 8 channels to be combined or separated. The filters operate with a channel spacing of 20nm corresponding to standard CWDM wavelengths, offering low insertion loss, high channel isolation, and flat passband.

Channel Spacing (nm): 20 Center Wavelength (nm): 1471, 1491, 1511, 1531, 1551, 1571, 1591, 1611 Passband (nm): 13

Santec's C-CWDM module is specifically designed for low-cost CWDM systems where size and insertion loss are critical. It uses Santec dielectric thin-film coating technology to achieve low loss in a compact package, approximately one-tenth the size of a conventional 8-channel mux/demux module. The module offers excellent optical performance with high isolation between channels and low PDL, meeting the price and performance requirements of modern metro and access networks.

Insertion Loss (dB): ≤0.5 Return Loss (dB): ≥50 Operating Wavelength Range (nm): 1260-1650

This optical fiber distribution module is designed for efficient fiber optic signal management and distribution in telecommunication networks.

Wavelength Range (100GHz): 1520-1610nm Channel Spacing (100GHz): 100GHz Number of Channels (100GHz): 4

The MDM-15 is a multi-channel WDM Multiplexer or Demultiplexer based on dielectric thin-film filter technology. The module is designed to add or drop 4 channels with ITU grid spacing of 100, 200 or 400GHz. Channels can be dropped with high adjacent channel isolation and all channels are subject to low insertion loss. The MDM-15 can also be configured with an additional band splitting filter to enable device cascading in DWDM systems. In Mux and Demux configurations the filter specifications can be tailored to the end-users performance and cost requirements. The "Upgraded" MDM-15 has a common input and output port enabling an express channel for channels which are not to be dropped. Alternatively, the terminated MDM-15 (without express port) realizes lower insertion loss for each channel.
