1550nm Band Pass Filter

This bandpass filter is fabircated using thin film filter chips. Three different pass band widths can be supplied, 2nm, 5nm or 6.6nm. This filter can be used to filter out ASE noise in EDF amplifiers, or fiber laser systems. This product features high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.

Standard SMF or PMF pigtail fiber can be supplied.

Features:

• Low insertion loss
• High isolation at stopband
• High stability and reliability

Applications:

• Optical fiber amplifiers
• Optical fiber lasers
