The 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 fiber amplifier 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.

*Above specifications are for device without connector.
*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, ER (PM fiber) will be 2dB lower. Power transmits through the connector less than 2W.
*PM band pass filter is both axis working, but the PM fiber and the connector key are aligned to the slow axis.
*For >10W high power applications, we will use heat sink package, contact OPC 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.
