Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output.
Fiber optic coupler is different from WDM. WDM can divide the different wavelength fiber light into different channels. Fiber optic couplers divide the light power and send it to different channel.
Single window fiber optic coupler is with one working wavelength. Dual window fiber optic coupler is with two working wavelength. For Single mode fiber, the term means that the fiber is optimized for 1310 nm and 1550 nm; For Multimode fiber, the term means that the fiber is optimized for 850 nm and 1310 nm.
Choices for fiber optic coupler type include Single window fiber optic couper, Dual window fiber optic copuler, Wide band fiber optic coupler.
Single window fiber Optic couplers (1310 +/-10nm or 1510 +/-10nm) are designed for a single wavelength with a narrow wavelength window.
1. Standard Singlemode coupler
2. Singlemode Tree coupler
3. Unitary 1(3) x 3 coupler
Dual window fiber Optic couplers (1310 +/-40nm and 1510+/-40nm) are designed for two wavelengths with a wide wavelength window for each.
1. Dual window wideband coupler
2. Dual window Tree coupler
3. Dual window Star coupler
4. Unitary 1X3 and 1X4 Dual Window Wideband
Wideband fiber optic couplers (1310 +/-40nm or 1510+/-40nm; 850nm +/-40nm or 1310nm+/-40nm) are designed for a single wavelength with a wider wavelength window.
1. Singlemode Wideband coupler
2. Unitary 1x3 wideband coupler (1310+/-30nm or 1510+/-30nm)
3. Wideband Tree coupler
4. Standard Multimode coupler
LFO Fiber Optic Couplers and Splitters are available in a variety of styles, sizes, port configurations, couple (split) values, and wavelength specifications allowing a high degree of flexibility in tailoring the product to suit your precise requirements and application.
