Other materials of Fiber Optic Patch Cable

More and more customers in USA asked about the Plenum fiber optic cables (OFNP), so we need to know the difference between OFNP, OFNR? Just like copper cables, NEC (National Electrical Code) requires indoor fiber optic cables be marked with their fire and smoking ratings. NEC requires all indoor fiber cables be marked correctly and installed properly for its intended use.
According to NEC, a building’s inside area is divided into three types of sections: plenums, risers and general purpose areas.

What is a Plenum area?
A Plenum area is a building space used for air flow or air distribution system. In most buildings, the area above a drop ceiling or under a raised floor is used as the air return (source of air) for the air conditioning. Those drop ceiling and raised floors are also where fiber cables are often installed. If those cables were burning, they would give off toxic fumes and the fumes would be fed to the rest of the building by the air conditioner. As a result, people could be injured even though they are a long way from the fire.

What is a Riser area?
A Riser area is a floor opening, shaft or duct that runs vertically through one or more floors.

What is General Purpose area?
All other area, which is not plenum or riser on the same floor, is a general purpose area.
 

OFNP Cables:
OFNP stands for Optical Fiber Nonconductive Plenum. OFNP cables have fire-resistance and low smoke production characteristics. They can be installed in ducts, plenums and other spaces used for building airflow. This is the highest fire rating fiber cable and no other cable types can be used as substitutes.
 

OFCP Cables:
OFCP stands for Optical Fiber Conductive Plenum. OFCP cables have the same fire and smoking rating as OFNP cables but they have a conducting armor or central strength member which is usually steel. OFCP cables must be properly grounded at both ends. As a result, OFCP cables can not be installed in the same cable tray or conduit as power cables.

OFNR Cables:
OFNR stands for Optical Fiber Nonconductive Riser. OFNR cables are used in Riser areas which are building vertical shafts or runs from one floor to another floor. OFNR cables can not be installed in plenum areas since they do not have the required fire and smoking rating as Plenum rated cables. OFNP plenum cables can be used as substitutes for OFNR cables.

OFCR Cables:
OFCR stands for Optical Fiber Conductive Riser. OFCR cables have the same fire rating characteristics as OFNR cables but they have conducting armor or central strength member which is usually steel. OFCR cables should also be properly grounded at both ends. OFCP cables can be used as substitutes for OFCR cables. OFCR cables can not be installed in the same cable trays or conduits as power cables.

OFNG Cables:
OFNG stands for Optical Fiber Nonconductive General-Purpose. They are typically used in horizontal cabling, single floor applications. OFNG cables cannot be used in plenums or risers. OFNP and OFNR cables both can be used as substitutes for OFNG cables.

OFCG Cables:
OFCG stands for Optical Fiber Conductive General-Purpose. They have the same fire characteristics as OFNG cables but they have conducting armor or central strength members which is typically steel. OFCG cables should be properly grounded at both ends. They should not be installed in the same cable tray or conduits as power cables.

Patch Cord ESCON Connector

The ESCON* architecture was developed to improve connectivity between mainframe, its peripherals, and other networks. The connector system is a retractable shroud duplex meeting IBM* requirements.In addition to basic testing, some mechanical and environmental tests per IEC or Telcordia are also performed periodically to guarantee the best quality. For standard patch cords, sampling check is performed on ferrule geometry to ensure high percentage of polished connectors meeting GR-326 requirements. For premium grade, ferrule geometry is tested on all patch cords to meet these GR-326 requirements.Other than standard single mode and multimode fibers, OM2, and OM3 fibers are also available upon

Fan-Out Patch Cord

Fiber optic fan-outs are designed for patch panels or cable ducts where space-saving is required. The patch panels have either array fusion splicing (between outside plant cables and bare ribbon pigtails) or array interconnections (MPO/MTP fan-out). For cables that run from patch panels to equipment or patch panels to patch panels, the fan-out cords with either ribbon cables or distribution cables can save space for cable ducts. Distribution cables are more rugged than ribbon cables. Most popular connectors, such as SC, FC, ST, LC, E2000, MU, DIN, D4, and MPO/MTP are available. A fan-out cord can have MPO/MTP at one end, and fan-out terminated with single fiber connectors at the other

Patch Cord FC Connector

The FC* connectors used in our patch cords are designed to NTT-FC* standards with high quality zirconia ferrules and non-optical disconnect performance. They are fully compatible with existing FC hardware. In addition to basic testing, some mechanical and environmental tests per IEC or Telcordia are also performed periodically to guarantee the best quality. For standard patch cords, sampling check is performed on ferrule geometry to ensure high percentage of polished connectors meeting GR-326 requirements. For premium grade, ferrule geometry is tested on all patch cords to meet these GR-326 requirements.Other than standard single mode and multimode fibers, G655, OM2, and OM3 fibers are also
