In the past, we've talked about some of the key differences between single mode and multi mode fiber optic cables, namely as they apply to things like bandwidth. But are all multi mode fiber cables alike? offers OM3 and OM4 fiber optic cables for purchase, and today we'll delve into what makes these cables different from each other.

OM3 vs OM4 Fiber Optic Cable

Multi mode fiber optic cables usually feature a standard aqua blue jacket, which might make them hard to distinguish from each other. Datacomm manufactures both our OM3 and OM4 cables in the US, and they're assembled using high-quality materials for optimum performance. But there are different types of multi mode fiber cables! 

OM3 Fiber Optic Cable

What makes our OM3 fiber optic cords so special? They're constructed from aqua 50/125 riser rated jackets with a slim 2mm diameter, making them a great fit for dense network switches in data racks. Another plus is that they're fully compatible with both OM2 and OM4  fiber cables. Our OM3 cables feature high quality duplex connectors on either end, and they're available in a variety of connector configurations including LC to LC, LC to SC, LC to ST, and ST to ST. We also provide plenum-rated OM3 cables, which are self-extinguishing, flame retardant, and UV resistant.

But what about their signal strength? This is where the difference from OM4 cables is key. OM3 fiber optic cable is rated for 10GB up to 300 meters. They're capable of transmitting at speeds at 40GB up to 150 meters, or even 100GB up to 100 meters.

Are you looking for an OM3 Fiber optic cable with a boot? You can check out our 10GB Aqua Flex Boot Fiber Optic Cable, which can be safely bent up to 90 degrees at either end. 

OM4 Fiber Optic Cable

Here's that key difference between OM3 fiber cables and OM4 fiber cables again: our OM4 fiber optic cords can achieve 40G performance over 150 meters, and 100G over 100 meters. Like our OM3 cables, these fiber patch cables are a big step up from copper cables. They're available in the same variety of configurations as the OM3 cables, but it's important to keep in mind that whichever cable you decide on for your data network, you'll always have the option of purchasing in custom colors and lengths from

OM4 fiber optic patch cords can be combined with OM3 cables in any network, panel, or data center environment. If it's a more sturdy cable you're looking for, stocks OM4 LC to LC Armored Fiber Optic Patch Cables which are constructed at a rugged 3mm diameter for use in installations where they might be exposed to lots of dust, moisture, or rodents. It's important to us that you find a cable that will meet your needs and stand the test of time.
