High Performance IEC Grade B Patch Cord

INTRODUCTIONS

- For high-speed fiber-optic communications and data networks, high-performance fiber jumpers mean lower insertion loss and better random interchangeability. IEC Grade B-class patch-cord require higher processing technology and materials than ordinary products. We offer reliable and stable IEC Grade A / B / C grade patch-cord. 

FEATURES

- Conforms to IEC 61753-1 and IEC 61300-3-34

- Low insertion loss, low return loss

- Random test interchangeability is good

- High precision ferrule and connector material

- Products comply with Telcordia, IEC, RoHS, REACH

Beside to use low concentricity ferrules for the products, all the Grade B connectors must be tuned by using the fiber core adjustment machine. This is a very important procedure to make high quality Grade B connectors. 100% connectors will be tuned in KOC factory
