Wavelength Division Multiplexer Couplers
The WDM separates or combines wavelengths in the 1310 and 1550nm bands over an
ultra-wide bandwidth (+ 20nm) and temperature range while maintaining excellent stability
and optical performance. The device, which is fabricated using an advanced fused biconi-
cal taper technology, is designed to meet Telcordia 1209 and 1221 requirements.
Features
• Low insertion loss
• Ultra-wide bandwidth
• Wide operating temperature
• Low PDL
• Highly stable and reliable
• Epoxy-free optical path
