1X2 Multimode Fiber Fused Coupler/Splitter 3.0Mm With ST/UPC Connectors

1×2 Multimode Fiber Fused Coupler/Splitter 3.0mm with ST/UPC 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
