Frequently Asked Questions
What is the maximum fiber optic cable distance supported by the DFE-855? +
The D-Link DFE-855 is designed for short to medium-range fiber connectivity, supporting a maximum transmission distance of up to 2 kilometers. This makes it an ideal solution for extending 100Base-TX copper segments across a facility or campus environment using multi-mode fiber cabling.
Does the DFE-855 require specific fiber optic cable types? +
This media converter utilizes a multi-mode optical interface operating at a 1310nm wavelength. To ensure optimal performance and signal integrity, you should deploy multi-mode fiber patch cables with SC connectors that match the specific fiber core diameter required by your existing network infrastructure.
What type of physical connectors are used on the DFE-855? +
The device features a standard RJ-45 port for the 100Base-TX copper connection and an SC-type interface for the 100Base-FX fiber connection. The SC interface is a widely adopted industry standard, ensuring robust and reliable mechanical connections for your fiber optic backbone.
Can the DFE-855 bridge a standard copper switch to a fiber backbone? +
Yes, this photoelectric converter acts as a transparent bridge between your copper-based Ethernet equipment and fiber optic infrastructure. It seamlessly converts 100Base-TX electrical signals to 100Base-FX optical signals, allowing you to integrate legacy or standard copper switches into a fiber-dominant network architecture without replacing your existing hardware.
Is the DFE-855 suitable for high-speed Gigabit Ethernet networks? +
The DFE-855 is strictly rated for 100Mbps Ethernet performance. It is intended specifically for 100Base-TX to 100Base-FX conversion. If your environment requires Gigabit speeds, this specific model will not be compatible, and you should look for converters that support 1000Base-T to 1000Base-SX/LX standards.
How do I monitor the link status on the DFE-855? +
The DFE-855 provides integrated LED indicators that offer real-time status monitoring for both the copper and fiber ports. These status lights allow network administrators to quickly verify link activity, power state, and data transmission, simplifying physical layer troubleshooting during deployment or maintenance tasks.
Does the DFE-855 support full-duplex transmission? +
The converter supports full-duplex operation, which is standard for 100Base-FX fiber links. This allows for simultaneous bidirectional data flow, effectively doubling the available bandwidth compared to half-duplex configurations and preventing collisions, which is essential for maintaining high efficiency in busy enterprise data environments.
What is the primary use case for deploying the DFE-855 in an enterprise setting? +
The DFE-855 is primarily deployed to overcome the distance limitations of Cat5/Cat5e copper cabling. By converting to fiber, IT teams can extend network connectivity up to 2km, effectively isolating copper segments from electromagnetic interference (EMI) or connecting disparate server rooms that exceed the 100-meter threshold of standard copper Ethernet.
How can I obtain a bulk quote for the DFE-855 from BuyRouterSwitch.com? +
