Features and Benefits
Single Fiber WDM Transmission:
Employing bidirectional WDM technology, it transmits and receives data on a single strand of fibers, requiring only half the cable compared to conventional converters.
Reliable 100 Mbps Speeds:
Offers reliable 10/100 Mbps data connections perfect for regular data communications, security cameras, wireless LAN access points, and simple LAN bridging.
Auto MDI/MDIX:
Automatic cable type recognition, so no crossover cable is required.
Easy Monitoring:
Front LED indicators allow easy determination of power and link status.
LDLC Easy Setup:
No software or complicated configuration required — just plug in the Ethernet and fiber cables and turn on.
Compact & Lightweight:
It weighs. Its compact size allows it to be mounted on desks or shelves and even on small network racks. TP-
Where You Can Use This Product
Highly recommend this media converter for instances involving extension or integration of your network’s fiber connections:
- Connecting campuses and buildings beyond the range of copper Ethernet.
- Long-range networking for IP camera systems.
- Wireless network backbones connecting remote access points.
- Networks for industrial or outdoor usage, with a focus on reliable links.
Easy Technical Explanation
A media converter, such as the TL-FC111A-20, will take a standard copper cable Ethernet signal and transmit it via a fiber optic signal and vice versa. It will enable communications on devices that would not have been able to communicate with each other before, because they are either too distant or because of cable limitations. It can transmit and receive on only one cable line because it uses WDM.
Why You Need This Product
But if your network requires an extension of range beyond the normal range offered by Ethernet cable (100 m), or if you want to upgrade your network from copper cable to fiber without having to discard your current networking equipment, then it would be very useful for you to have something like the TL-FC111A-20. It would help your business have better and more reliable networking performance without requiring you to set everything up manually.
