Introduction

In this article we will talk about the 100BASE-FX Ethernet standard and its optical transceivers and which brands these are compatible with and their basic solutions, All this just to give you more understanding about 100BASE-FX technology. You can also check the compatibility Cozlink transceivers to get compatible and cost-effective products.

What is the 100BASE-FX technology?

100BASE-FX is a version of Fast Ethernet over optical fiber. It uses a 1300 nm near-infrared (NIR) light wavelength transmitted via two strands of optical fiber, one for receive (RX) and the other for transmit (TX). Maximum length is 412 metres (1,350 ft) for half-duplex connections (to ensure collisions are detected), and 2 kilometres (6,600 ft) for full-duplex over multi-mode optical fiber. 100BASE-FX uses the same 4B5B encoding and NRZI line code that 100BASE-TX does. 100BASE-FX should use SC, ST, LC, MTRJ or MIC connectors with SC being the preferred option. The 100BASE-FX Physical Medium Dependent (PMD) sublayer is defined by FDDI's PMD, so 100BASE-FX is not compatible with 10BASE-FL, the 10 MBit/s version over optical fiber.

Benefits of 100BASE-FX

After a decade of existence, there are still good reasons to use 100-FX. There are many applications where higher speed is not needed and where there is existing multimode fiber in place. When 100 Megabits/sec is adequate, there are several benefits of 100-FX:

• can extend the network to greater distances than copper cabling can support
• noise immunity (fiber is immune to external interference)
• security (fiber is difficult, though not impossible, to tap)
• electrical immunity (there are no grounding issues with fiber)

Factories can be difficult environments for computer networks due to many sources of external interference that can affect the signal on copper cabling. For factories, fiber-based networks are often the only option. 

In large campus environments, fiberoptic cabling is required to reach the distances between buildings. Because of the FDDI legacy, many of those fiberoptic links are constructed of multimode fiber with distances no greater than two kilometers. When 100-Megabit communication is adequate, this campus example is a perfect fit for 100-FX. Department stores and grocery chains are other examples where 100-Megabit communication is adequate, but the challenges are long distances from the computer room to the point-of-sale devices and cash registers. Again, 100-FX is ideal for such a network. Military and other high-security networks often standardize on fiber optic networking because of its inherent security: signals do not "leak" from the cables, and the cables are very difficult to tap without being detected. Finally, cost is a big benefit of 100-FX, because 100-FX typically uses LEDs instead of highercost lasers. With less expensive transceivers at each end of the link, the overall system cost is lower. Existing multimode fiber segments further reduce the cost by allowing customers to reuse that fiber instead of installing new fiber.

What is the difference between 100BaseFX and 100BaseTX?

By the middle of 1990s, all 10Mbit/s Ethernet installation base have been upgraded to 100Mbit/s Fast Ethernet. The fiber standards for Fast Ethernet include 100Base-FX, 100Base-SX and 100Base-BX.

100Base-FX uses a 1300nm multimode light. The maximum length is 2 kilometers for full duplex over multimode optical fiber.

100Base-SX is the lower cost alternative to 100Base-FX. It uses 850nm light and can only operate at distance up to 300 meters.

Conclusion

As a lot of brands are only compatible with their own devices and this is where the third-party compatible optical transceiver becomes really important to insure ensures that the brands are equipment of these brands are compatible with each other, Cozlink is one of the most trusted source to provide high performance transceivers which are compatible with a lot of different brands, Also, the prices you get on Cozlink is much less than the original manufacturer. All this makes stands out Cozlink as the perfect place for third-party compatible optical transceiver for 100BASE-FX Ethernet standard solution. Not just optical transceivers, you can also find fiber optic pigtails and high speed cables for your choice on Cozlink.
