FWDM Module - Hirundo Communication Equipment - Professional Manufacturer and Solution Provider

Filter wave divider (FWDM) uses high-performance film filters to ensure high-quality optical performance, stability and reliability. Filter wave division multiplexer can achieve 1310nm, 1550nm two-window optical signal of the combined wave and split wave, so that a single fiber transmission capacity multiplied, but also to achieve fiber two-way communication, widely used in fiber upgrade, expansion or introduction of integrated new services, such as radio and television, telecommunications, Internet and so on.
