In optical communication networks, Hiphotonics' Fused Wavelength Division Multiplexer (WDM) is an optical tool for either merging or splitting optical signals of various wavelengths. Multiplexing and de-multiplexing—which let the WDM transmit several optical signals over a single optical fiber—are its guiding concepts. Operating on single-mode fibres, fused WDMs have low insertion loss, minimal excess loss, and quite low polarisation sensitivity. Tight quality standards and proven fused biconical taper technology are employed in manufacture to guarantee great dependability and performance.
Couplers, filters, and isolators are among the several devices available for the Fused WDMs running in 1465 nm and 1550 nm. The WDMs feature a flat passband with rather minimal excess loss and insertion loss. The variation between the loss in the passband and the loss in the stopband constitutes the excess loss. The minimal excess loss of the fused WDMs guarantees that the optical signal is not much attenuated during the multiplexing or de-multiplexing operation.

Strict tests guarantee the dependability of Fused WDMs, therefore completely meeting Telcordia GR-1221 criteria. The quality standard Telcordia GR-1221 is used to assess the dependability of fiber-optic devices applied in communications networks. The standard specifies the ambient parameters, test techniques, and acceptance criteria the devices have to satisfy in order to guarantee their dependability and performance throughout operation.
Essential parts of optical communication networks, fused wavelength division multiplexers allow several optical signals to be sent over one optical fibre. Made utilising proven fused biconical taper technology and strict quality processes, the Fused WDMs operating in the 1480nm and 1550nm bands guarantee dependability and performance. Combining or splitting optical signals is best served by the low insertion loss, flat passband, low excess loss, and very low polarisation sensitivity Fused WDMs.
