    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.

    Kocent Optec Limited is one of our company longterm partner. We order 2 to 3 containers 40' from them each month. I agree that their outdoor cable, distribution box, splice enclosure and fiber optic accessories quality is very nice. Under their support, we win many telecom projects. Thank so much.

Product Description
Single Mode 4 Four Port Fiber Optic Cable Splitter Laser Circulator High Power
Single Mode 4 Four Port Fiber Optical Laser Circulator High Power for 1064nm, 1310nm, and 1550nm wavelengths. Available with no connectors, FC/PC connectors, FC/APC connectors, or other connector types upon request.
Product Overview
Our fiber optic circulators come in two types: single mode and polarization maintaining (PM). The 4-port optical circulator is a compact, high-performance component that transmits signals sequentially from port 1 to port 2, port 2 to port 3, and port 3 to port 4. It features high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.
Key Applications
  • CATV systems
  • Telecommunication network systems
  • Metro/Access networks
  • Optical amplifiers
  • Wavelength add/drop
  • Dispersion compensation
  • Bi-directional communication
Product Features
  • Four-port operation
  • Wide band (±30nm at 1310nm or 1550nm)
  • High isolation and low PDL
  • Epoxy-free optical path
  • Low insertion loss
  • Compact in-line package
  • High stability and reliability
