Features • Dual window wideband operation • Low insertion loss over entire band - width and temperature (typical IL change <±0.1 dB) • 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 • Fully tested to Telcordia 1209 and 1221 criteria Wideband Couplers The dual window Wideband Couplers (WBC) split or couple optical power in two wave - length 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’s fused biconic technology, and is designed and manufactured to meet military and Telcordia ® requirements.
