WideCap-OM4 multimode fibre delivers OM4 performance in the 850-950nm window while maintaining compatibility with current multimode fibres. Traditional OM4 fibres offer high bandwidth in a narrow band centred at 850nm. To satisfy the exponentially increasing information demand in Data Centers, the capacity of WideCap-OM4 has been extended to longer wavelengths up to 950nm. WideCap-OM4 and multi-wavelength transceivers are a viable solution for future 100 and 400Gbps multi-wavelength systems. WideCap-OM4 incorporates BendBright® technology to withstand tight bends and cabling challenges in the data centre.
