COMMUNICATIONS COMPONENTS
Key Features • Low insertion loss
• High power handling
• Proven reliability
• 9xx, 14xx and 15xx variants
The JDSU Fused Coupler, PM Combiner enables the efficient combination of two
orthogonally polarized sources of light at the same wavelength such that they are
output through the same, single fiber output. In optical amplifiers this provides a
doubling of pump power whilst ensuring pump redundancy should a pump
failure occur. Applications include high power optical amplifiers and undersea
systems. All ports consist of polarization maintaining fiber.
Applications
• Erbium doped fiber amplifiers (EDFAs)
• Raman amplifiers
• Coherent optical communications
