1X2 Multimode Fiber Fused Coupler/Splitter 0.9mm Without Connectors

1×2 Multimode Fiber Fused Coupler/Splitter 0.9mm without connectors

Multimode optical fiber couplers are widely used in optical local networks or FTTx networks that use multimode fibers. These couplers can be fabricated using 50/125 or 62.5/125 micron fibers and at central wavelengths of 850nm or 1310nm (other wavelengths available upon request).
Features:

• Broad operating band
• Low excess loss
• High stability and reliability

Applications:

• Multimode fiber communication systems
• Optical LAN
• Test instruments
• Optical fiber sensors
