Because the future is fiber.

Beyond Limitations: Unleashing Endless Connectivity with the Power of Fiber Optics.

Faster bandwidth capacity

Superior Speed: Fiber optic cables provide significantly higher data transmission speeds compared to traditional copper cables,  enabling faster and more efficient communication within a network.

Low latency

Latency, is the time it takes for data to travel from one point to another. Fiber optics can handle large volumes of data without any latency issues, ensuring seamless browsing, downloading, and streaming experiences.

Better security

Fiber optic cables don’t radiate signals, and are very much harder to tap than copper cables since there is no electric current involved. Monitoring cable leaks are easy since they light up and causes the entire system to fail.

Long distance connectivity

Fiber optic lines are designed to effectively move data at long distances. Unlike copper cables, fiber optics experience minimal signal loss over long distances.

Long-term cost-effective

Energy efficiency of fiber optic connections leads to reduced utility bills for businesses. Increased productivity due to faster data transmission can result in significant time and cost savings.


Since they use light signals instead of electrical currents, they do not produce electromagnetic fields or emit significant amounts of carbon dioxide during data transmission. This makes fiber optics a greener choice.

Singlemode vs Multimode Fiber Optic Cable

Single mode means the fiber enables one type of light mode to be propagated at a time. While multimode means the fiber can propagate multiple modes. The differences between single mode and multimode fiber optic cable mainly lie in fiber core diameter, wavelength & light source, bandwidth, color sheath, distance and cost.

Core Diameter

Single mode fiber core diameter is much smaller than multimode fiber. Its typical core diameter is 9 µm even if there are others available. And multimode fiber core diameter is 50 µm and 62.5 µm typically, which enables it to have higher "light gathering" ability and simplify connections. The cladding diameter of single mode and multimode fiber is 125 µm.


Multimode fiber bandwidth is limited by its light mode and the maximum bandwidth at present is 28000MHz*km of OM5 fiber. While single mode fiber bandwidth is unlimited theoretically because it allows only one light mode to pass through at a time.

Color Sheath

According to the TIA-598C standard definition, for non-military applications, single mode cable is coated with yellow outer sheath, and multimode fiber is coated with orange or aqua jacket.

Fiber Distance

It’s known that single mode fiber is suitable for long-distance applications, while multimode optical fiber is designed for short-distance runs. 

Fiber Cost

Single-mode optical fiber often costs less than multimode fiber. When building a 1G fiber optic network that you want to be able to go to 10G or faster on eventually, the savings on the cost of fiber for single-mode saves about half-price. While the multimode OM3 or OM4 fiber increases 35% in cost for SFP modules. The single-mode optics are more expensive, but the labor costs of replacing the multimode are significantly higher, especially if that followed OM1—OM2—OM3—OM4. 

single mode fiber and multimode fiber cable have their own advantages on cost and applications. There is no such thing that single mode optical fibers are better than multimode ones. Just choosing the best-fit one for your applications is ok.

This answer for this question is “no”. Multimode fiber and single mode fiber have different core sizes, and the number of light modes that they transmit is also different. If you mix the two fibers, or connect them together directly, you’ll lose a large amount of optical loss, resulting in a link flapping or being down. Keep in mind that never mix different types of cabling randomly.

Generally speaking, the answer is "no". Large optical loss will occur if a multimode transceiver is connected with single mode fiber. However, the opposite will work. For example, 1000BASE-LX single mode SFP can work on multimode fiber cable by using mode conditioning fiber cable. Sometimes, fiber media converters also can be used to solve such problems between single mode transceivers and multimode transceivers.

When making a decision between single mode and multimode fiber cables, the first factor to consider is the fiber distance which you need actually. For example, in a data center, multimode fiber cables are enough for the distance of 300-400 meters. While in applications that require distance up to several thousands of meters, the single mode fiber is the best choice. And in applications that can use single mode and multimode fiber, other factors like cost and future upgrade requirements should be taken into consideration for your choice.
