User Manual
FAQ
What types of fiber optic cable does this media converter support?
The FC311A-20 supports single-mode fiber optic cables with 9/125 µm core/cladding specifications. It is designed for use with SC duplex connectors and operates at 1310 nm and 1550 nm wavelengths, enabling long-distance communication up to 20 km without signal degradation.
What is the maximum distance this converter can extend a network?
This media converter supports network extension up to 20 kilometers (approximately 12.43 miles) when using single-mode fiber optic cables. The distance capability is achieved through WDM technology and optimized signal transmission at Gigabit Ethernet speeds, making it suitable for campus, industrial, and remote connectivity applications.
Does the RJ-45 port require manual configuration for speed and duplex settings?
No, the RJ-45 port features full auto-negotiation, automatically detecting and adjusting to the connected device's speed (10/100/1000 Mbps), duplex mode (half or full duplex), and MDI/MDIX crossover requirements. This plug-and-play functionality eliminates manual configuration and ensures compatibility with a wide range of network equipment.
What is WDM technology and how does it benefit this converter?
Wavelength Division Multiplexing (WDM) allows the converter to transmit and receive data simultaneously over a single fiber strand using different wavelengths (1310 nm and 1550 nm). This reduces cabling requirements by eliminating the need for separate transmit and receive fibers, lowering infrastructure costs while maintaining full-duplex Gigabit performance over extended distances.
Can this media converter be mounted in a standard equipment rack?
Yes, the FC311A-20 supports both standalone desktop use and rack mounting.
