An optical circulator is a component that can be used to separate optical power that travels in opposite directions in one single fiber. Gooch & Housego’s single mode (SM) and polarization maintaining (PM) regular- and high-power circulators offer low optical loss and high reliability across a wide range of wavelengths up to 10 W.

A fiber optic circulator is a three-port device that allows light to travel in only one direction from port 1 to port 2, then from port 2 to port 3. Fiber circulators are known for their reliability in increasing transmission capacity of existing networks.

Because of their high isolation and low insertion loss, optical circulators are widely used in advanced communication systems. With the development of advanced optical networks, applications of optical circulators are expanding rapidly from communication systems to medical and imaging fields such as OCT applications.

Gooch & Housego (G&H) offers a selection of highly reliable fiber optic SM and PM circulators suitable for your applications. G&H low wavelength fiber optic circulators (3 port and 4 port) are offered at 780, 810, 850, 980, 1030 and 1064 nm. G&H also offers 3 port SM as well as 3 port and 4 port PM fiber optic circulators that operate at 1310, 1480, 1550, 1580, 1625, 1650 and 2000 nm, covering C+L and S+C+L-bands.

Four different versions of G&H fiber optic circulators are available:

  • Single mode (SM) circulators (CIRC-x-xx-x-x2-xxx series)
  • High-power single mode (SM) circulators (HSCR-x-xx-xx-xx-xx0 series)
