VALUE 21.99.1069 100 Mbit/s Multimode Grey Network Media Converter

The VALUE 21.99.1069 is a network media converter for converting a Fast Ethernet TP (twisted pair) port to multimode fiber. It supports full wire-speed conversion for 10/100 Mbit/s and provides a transparent pass-through for 802.1Q VLAN-tagged packets. The unit includes a shielded RJ-45 TP port with auto MDI/MDI-X and auto-negotiation for speed and duplex, and an SC duplex FX port compliant with 100Base-FX for multimode fibre (50/125 µm and 62.5/125 µm). The converter is powered by the included 5 VDC, 1 A power supply and has low power consumption (2.5 W). Note: this device does not provide a repeater function.

Advantages

The converter offers reliable 10/100 Mbit/s media conversion with transparent handling of 802.1Q VLAN tags, low power consumption and compact design. It supports both common multimode fibre core sizes (50/125 and 62.5/125 µm) and automatic TP port configuration (auto MDI/MDI-X, auto-negotiation), simplifying installation and integration into existing networks.

Suitable for

• Extending wired Ethernet segments over multimode fibre up to the supported distance
• Connecting 10/100 Mbit/s copper devices to multimode fiber infrastructure
• Integrations where preservation of 802.1Q VLAN tags is required

How to use

Connect the copper Ethernet cable to the shielded RJ-45 TP port and the multimode SC fibre cable to the duplex FX port. Provide power using the supplied 5 VDC, 1 A power adapter. The TP port will automatically detect MDI/MDI-X configuration and negotiate speed and duplex. The FX port operates at forced 100 Mbit/s full-duplex; ensure fibre type and connectors match the converter specifications. Verify link LEDs (if present) and test end-to-end connectivity after installation. Remember that the device does not regenerate signals like a repeater.

Recommendations

Use appropriate multimode fibre (50/125 µm or 62.5/125 µm) with SC duplex connectors and keep fibre runs within the supported distance. Avoid using the converter where active signal regeneration or repeater functionality is required; instead, use switches or repeaters when needed. Ensure the included 5 VDC/1 A power supply is used and routed to prevent accidental disconnection.
