Project Description

1053nm Band Pass Filter

The 1053nm Band-pass Filter is a micro optics device based on environmentally stable thin-film filter technology. It is used to block out unwanted noise signals in EDFAs or fiber laser systems. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high-power handling capability. They are ideal for fiber amplifiers, fiber lasers, and high-speed communication system and instrumentation applications.

Features Applications
·         Low Insertion Loss

·         High isolation

·         High power handling

·         High Stability and Reliability

·         Fiber laser

·         Fiber amplifier

*Above specifications are for device without connector.

*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, Power transmit through the connector less than 2W.

*For >10W high power applications, we will use heat sink package, contact DK Photonics for details.

*Since the function of the BPF is to blocked unwanted noise signals, the blocked light remains in the interior of the housing, so we do not recommend applying it to too high power, or adding reflection port to reflect the blocked light.

Package Dimension

In-line Polarizer

*Due to ongoing design improvements, the package size is subject to change. Please contact DK Photonics for confirmation.

Order information P/N: BPF-①-②-③-④-⑤-⑥

When you inquire, please provide the correct P/N number according to our ordering information, and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail.
