Our single mode optical couplers work at either 1310nm or 1550nm. They are fabricated using single mode fibers. They have operation bandwidth of 40nm around its central wavelength. The excess loss is very low, no greater than 0.15dB for grade A product and no greater than 0.1dB for premium grade product.

Customers can choose the coupling ratios from the standard values, 50/50, 40/60, 20/80 or 10/90. Also, customers can specify their required coupling ratios.

Different pigtails, package types and connectors can be specified.



  • Low excess loss
  • Low PDL
  • High stability and reliability



  • CATV systems
  • Optical communication systems
  • Test instruments


Ordering Information:

w: Center Wavelength in nm; w=1550 or w=1310.
a: Port Number of the coupler; a=1x2 or a=2x2.
b: Quality Grade; b=A or b=P (premium grade).
e: Coupling Ratio of the coupler; e=50/50 for 50% coupling ratio; e=10/90 for 10% coupling ratio; e=5/95 for 5% coupling ratio, etc.
