The dual window Wideband Couplers (WBC) split or couple optical power in two wavelength regions while maintaining a very broad operating bandwidth. Split and coupling ratios are available from 5% to 50%. WBCs are widely considered one of the most cost-effective solutions to optical power management. The WBC is an all-fiber device, based on AFL Telecommunications’ fused biconic technology, and is designed and manufactured to meet Military and Telcordia requirements.
Features:
•
Dual window wideband operation

Low insertion loss over entire bandwidth and temperature (typical IL change <±0.1dB)
•
Ultra-low PDL and temperature sensitivity
•
High directivity
•
Compact design
•
Environmentally stable, over 10 years of proven field reliability
•
Standard operating temperature range -4O °C to +85 °C
