15M OM4 LC to SC Multimode Duplex Fibre Patch Cable in Aqua

Introduction

OM3 and OM4 multimode fiber are two common types of fiber used in local area networks--typically in backbone cabling between telecommunications rooms and in the data center between main networking and storage area network (SAN) switches.

Both of these fiber types are considered laser-optimized 50/125 multimode fiber, meaning they both have a 50 micron (µm) diameter core and a 125 µm diameter cladding, which is a special coating that prevents light from escaping the core. Both fiber types use the same connectors, the same termination and the same transceivers--vertical-cavity surface emitting lasers (VCSELs) that emit infrared light at 850 nano meters (nm).

The difference between OM3 and OM4 multimode cable is that OM4 provides a higher modal bandwidth--4700 MHz·km compared to 2000 MHz·km for OM3. This means that OM4 can transmit more information within the same distance.

Since the attenuation of OM4 is lower than OM3 fiber and the modal bandwidth of OM4 is higher than OM3, the transmission distance of OM4 is longer than OM3. Details are shown in the table below. According to your network scale, to choose a more suitable cable type.
