10/100M Fiber Media Converter – SC Single Mode 20km with UK Power Adapter

Copper Ethernet has a hard limit — 100 metres, and that is on a good day with clean cabling. The moment your network needs to bridge a building, cross a campus, or reach a remote site down the road, you need fiber. But replacing all your existing Ethernet hardware is neither practical nor affordable. That is exactly the problem the 10/100M Fiber Media Converter solves. It transparently converts your standard RJ45 copper connection into a single mode SC fiber link, extending your network reach up to 20 kilometres — no reconfiguration, no new switches, no specialist knowledge required. Just plug in, connect, and your network reaches further than it ever could on copper alone.

What Is a 10/100M Fiber Media Converter and Why Do You Need One?

A fiber media converter is a small, passive-style device that sits between your existing copper Ethernet infrastructure and a fiber optic link. On one side, it accepts a standard 10/100 Mbps RJ45 connection from a switch, router, or end device. On the other, it connects to an SC single mode fiber patch cord and transmits that same data over glass — with no signal degradation across distances that would be completely impossible on copper.

The SA/SB model designation means this converter operates on a single fiber, dual-wavelength system. The SA unit transmits at 1310nm and receives at 1550nm; the SB unit does the reverse. Used as a matched pair, they carry full-duplex traffic over a single strand of fiber — cutting your fiber cabling cost in half compared to duplex solutions. For a deeper look at fiber transmission standards, the ITU-T G.652 standard defines the singlemode fiber specification this converter is designed to work with.

Key Features of the SC Single Mode 20km Media Converter

• 20km Transmission Range: Extends your 10/100 Mbps network over single mode fiber up to 20 kilometres — ideal for inter-building links, campus networks, and last-mile broadband deployments.
• SC Single Mode Interface: The SC connector is one of the most widely deployed fiber connector types in telecoms and enterprise infrastructure, ensuring broad compatibility with existing fiber plant.
• SA/SB Single Fiber Operation: Designed to work as a matched pair over a single fiber strand using dual wavelengths (1310nm/1550nm), significantly reducing fiber consumption and infrastructure cost.
• Auto-Negotiation: Automatically detects and matches the speed and duplex settings of connected Ethernet devices — no manual configuration needed on either end.
• Plug-and-Play Operation: No drivers, no software, and no complex setup. Connect the copper port to your network device, the fiber port to your fiber link, and the converter is immediately operational.
• UK Standard Power Adapter Included: Ships with a UK three-pin power adapter — ready to deploy straight out of the box without sourcing additional accessories.
• Link Fault Pass-Through: If the fiber link goes down, the converter signals the fault to the connected Ethernet device — making network monitoring and troubleshooting significantly faster.

Technical Specifications

Where the 10/100M Fiber Media Converter Fits In

This converter handles a specific and very common network challenge — extending connectivity beyond the reach of copper without replacing existing hardware. Here is where it is most useful:

• Campus and Multi-Building Networks: Connect two buildings across a courtyard, car park, or road without running new copper infrastructure or installing additional switches.
• FTTH Last-Mile Links: Bridge the fiber backbone to an ONT or customer-premises device where a direct fiber port is not available on the end equipment.
• ISP Point-to-Point Links: Extend a 100 Mbps service to a remote customer site or distribution point using existing single mode fiber plant and a matched SA/SB converter pair.
• Industrial and Security Networks: Connect IP cameras, access control systems, or industrial devices located far from the main network switch — all without signal loss across the distance.

Why Get Your Fiber Media Converter from ECA Networks?

Media converters are one of those products where the difference between a reliable unit and a frustrating one only shows up after installation — usually during a call from a client asking why their link keeps dropping. At ECA Networks, we stock converters that are tested for stable operation and genuine compliance with the specifications on the label. The SA/SB pair matching is verified, the power adapter is included and correctly rated, and the SC connector is polished to give you a clean fiber interface from day one.

We supply network hardware, passive fiber optic components, and connectivity accessories to ISPs, IT integrators, and enterprise teams across East Africa. Whether you need a single converter pair for a specific link or a bulk order for a wider deployment, we have the stock and the honest technical knowledge to help you get it right.
