| Product Description:
Lightwit’s Add/Drop filters are fabricated with thin-film interference coatings to achieve 100GHz narrow bandwidth channel filtering at ITU wavelength. These DWDM devices have low insertion loss, high channel isolation and stable environmental performance.
Key Features:
◆Low insertion loss
◆Excellent channel isolation
◆Epoxy-free optical path
◆Enviromentally stable and reliable
◆Low profile packaging
◆Telcordia (Bellcore) Compliant
Applications:
◆CWDM systems
◆Metro/Access communication networks
◆Fiber-optic instruments
