Red / Blue Optical Filters 1550nm 1310/85nm 1550/980nm For Optical Transmission

This Optical Filters Red/Blue product is a filter-based optical component designed for optical transmission and wavelength division multiplexing (WDM) systems. Operating within a wavelength range of 1260 to 1620 nm, it supports various combinations of transmission and reflection bands—including Red/Blue band splitting, 1550/980 combinations, and 1310/850 combinations—thereby meeting the diverse requirements for wavelength splitting, combining, bandwidth management, and link isolation across different systems. Utilizing highly stable filtering technology, the device features a maximum insertion loss of 0.6 dB at the transmission port and 0.4 dB at the reflection port. It offers a transmission isolation of ≥30 dB, a reflection isolation of ≥15 dB, and a maximum Polarization Dependent Loss (PDL) of just 0.10 dB. Characterized by low loss, low ripple, and stable output, this product is ideally suited for application environments where high demands are placed on link consistency and signal purity. The device supports a wide range of fiber configurations, including G657A1, G657A2, G657B3, SMF-28, as well as hybrid combinations such as SMF-28 & HI1060 and SMF-28 & OM1–OM5. Pigtail options include 250 μm bare fiber or 900 μm loose tube cabling, with a standard length of 1000 mm; connector options include LC/UPC or customized specifications. Available package dimensions include Φ5.5×L38, 90×20×10, 120×80×18, 155×129×29, and 482×250×44, facilitating seamless integration into modules, equipment installation, and OEM project implementation.
