4-Channel LWDM Wavelength DesignSupports four LWDM wavelengths: 1295.56 nm, 1300.05 nm, 1304.58 nm, and 1309.14 nm, enabling multiplexing and demultiplexing of multiple optical signals.
800G Channel SpacingUtilizes an 800G channel spacing design, with a passband range of λC ± 1.1 nm, suitable for O-band high-speed optical transmission applications.
Low Insertion Loss PerformanceThe module's insertion loss IL ≤ 1.6 dB, effectively reducing link power loss and improving system transmission efficiency.
High Isolation and Low CrosstalkAdjacent channel isolation > 25 dB, non-adjacent channel isolation > 35 dB, directivity > 50 dB, ensuring stable transmission of multi-wavelength signals.
Engineering Packaging and Connection ConfigurationUses 100×80×10 mm ABS box packaging, Corning SMF-28e fiber, 0.9 mm white conduit for cable numbering, fiber length 0.5 m, FC/APC interface, facilitating installation, testing, and maintenance.
