Product Highlights
Hirundo have a wide variety of single-mode (SM) or bias (PM) adjustable optical attenuators (VOA). These VOA are not terminaled or have FC/PC or FC/APC connectors. For this reason, we also provide an electronic VOA with output power that can be manually controlled or electronically controlled. Fiber connectors that fix optical attenuators can be connected to FC/PC or FC/APC single-mode fiber jumpers. We also offer fixed optical attenuators for SMA connector multimodal fibers.
