CWDM supports up to 18 wavelength channels transmitted through a fiber at the same time. To achieve this, the different wavelengths of each channel are 20nm apart. DWDM, supports up to 80 simultaneous wavelength channels, with each of the channels only 0.8nm apart. CWDM technology offers a convenient and cost-efficient solution for shorter distances of up to 70 kilometers. For distances between 40 and 70 kilometers, CWDM tends to be limited to supporting eight channels.
ORTE's Photonics truly fused polarization maintaining (PM) fiber optic couplers, Taps and Optical signal splitters offer high polarization extinction ratio (ER) with polarization launch into a single or dual axis (Slow axis & Fast axis). ORTE's Photonics utilizes our proven Fused Biconical Taper (FBT) process to manufacture high grade polarization maintaining couplers including single wavelength and wavelength flattened (Broadband/Wideband) (WFC). Our PM Components offer high extinction ratio with minimum optical loss. ORTE's Photonics utilizes PM fiber from different suppliers to accommodate your application specific operating wavelengths.
The filter wavelength division multiplexer can realize the combination and division of 1310nm and 1550nm optical signals of two communication Windows, which can double the transmission capacity of a single optical fiber and realize the two-way communication of fiber. It is widely used in the upgrading of optical fiber, expansion or the introduction of comprehensive new services, such as radio and television, telecommunications, Internet and so on.
