Ultra-compact Media Converter
A smaller Ethernet-to-fiber format for projects where enclosure footprint is a primary constraint.

The MR-1001S20 helps connect existing RJ45 Ethernet equipment to a single-mode optical path. Use this fiber media converter when the link calls for 10/100/1000M Ethernet, dual-fiber SM transmission, an SC interface and a 20 km planning boundary. For gigabit projects, the gigabit fiber media converter configuration should still be checked against the installed fiber plant, far-end equipment and link conditions.
Link Boundary
The model sits between two physical media. That simple boundary is the first check before comparing speed, distance or connector details.
Connects to nearby switches, control equipment, office-network devices or other Ethernet endpoints using the 10/100/1000Base-T side.
Converts electrical Ethernet signaling to optical signaling and back again, with plug-and-play setup and LED status feedback.
Uses the dual-fiber single-mode SC configuration for a link planned around the model's 20 km operating target.
This device extends or bridges an Ethernet link. It is not a substitute for routing, switching, PoE delivery or network-management functions that belong to other equipment categories.

Each term answers a different project question. Keep them separate when checking a bill of materials or preparing an inquiry.
| Model | MR-1001S20 |
|---|---|
| Ethernet side | 10/100/1000Base-T RJ45 wording for the copper connection |
| Optical side | 1000Base-SX/LX wording for the fiber connection |
| Fiber arrangement | Single-mode, dual fiber |
| Connector | SC optical interface configuration |
| Distance boundary | 20 km configuration; confirm actual fiber plant and link budget |
| Power / deployment | External 5V DC supply; standalone use or compatible Miray chassis installation |
| Installation aids | Plug-and-play design, auto-negotiation, auto MDI/MDI-X and LED indicators |

These three Miray articles answer different parts of the same procurement conversation, from category role to fiber-type selection.
Separate the Ethernet relationship from the physical medium so the converter is evaluated for the job it actually performs.

Questions Before Deployment
It bridges an Ethernet connection between an RJ45 copper side and a single-mode optical side. It changes the transmission medium rather than replacing a switch, router or managed network platform.
The product is named as a 10/100/1000M converter. Its copper-side wording is 10/100/1000Base-T, while the optical-side wording is 1000Base-SX/LX. Confirm the complete project link budget and far-end equipment before ordering.
The current model is built around single-mode, dual-fiber transmission with an SC connector and a 20 km configuration. The installed fiber plant, patching, loss and equipment at both ends still need to match.
The unit supports plug-and-play installation, auto-negotiation and auto MDI/MDI-X on the copper port. LED indicators provide operating-status feedback after the link is connected.
The product uses an external 5V DC power supply and can be used as a standalone unit or installed in a compatible Miray chassis for a centralized deployment.
Include the copper speed, fiber mode, target distance, connector type, far-end interface, power arrangement and whether the unit will be standalone or chassis-mounted. Miray can then review the link conditions with you.
