Mr Henry Thai
    Kocent Optec Limited is our long-term partner. In 8 years of co-operation times we together win many projects. Their fast connector and FTTH drop cable quality are best. Their products are cover my country now.
    Mr Pablo
    I was surprised when i made first order with Kocent Optec Limited in 2014. One container 40GP of GYXTW cable and one container 20GP for fast connector, patch cord and adapter. They finished this order in 2 weeks only. Now we also purchase many type of FDB box and Splice Closure Box from them. Hope we will be stronger and stronger in telecom field.

Product Description


Single Mode 4 Four Port Fiber Optical Laser Circulator High Power 1064nm 1310nm 1550nm



- We offer circulators with no connectors, FC/PC connectors, or FC/APC connectors or also other type of connector to match with customer request.

- There are two type of circulator, they are single mode fiber optic circulator and PM ( polarization maintaining) fiber optic circulator. 

- The polarization maintaining fiber optic circulator is available in 3 ports, 4 ports and 6 ports. 

The 4 ports optical circulator is a compact high performance lightwave component that transmits the incoming signal from port 1 to port 2, the 2nd signal from port 2 to port 3 and the 3 rd signal from port 3 to port 4.

- The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.

 - It is used in non-reciprocating systems, making light travel in a given direction while isolating light travelling in the opposite direction;

- Low insertion loss, high isolation and high extinction ratio;

- Used as an add/drop multiplexer in optical communication systems, for bi-directional pumping, fiber sensing and dispersion compensation.



- CATV system

- Telecommunication network system

- Metro/Access networks

- Optical amplifier

- Wavelength add / drop

- Dispersion compensation

- Bi-Direction communication



- Four-port operation

- Wide band (+/-30nm at 1310nm or 1550nm)

- High isolation

- Low PDL

- Epoxy free optical path

- Low insertion loss

- Wide band high isolation

- Compact in-line package

- High stability and reliability
