ROLINE Gigabit Converter, RJ45-Mini GBIC
Quick Installation Guide
Model: 21.13.1074
Introduction
This Gigabit Ethernet Media Converter is designed to bridge a 10/100/1000BaseT(X) copper signal to a 1000BaseSX/LX fiber optic signal. It effectively extends the communication distance between two Gigabit Ethernet twisted-pair devices using a fiber optic cable, ensuring transparent operation without performance degradation. The converter utilizes a switching hub design and supports Auto-Negotiation and Flow Control on its twisted-pair port. It features two SFP (Small Form-Factor Pluggable) slots that accommodate either multi-mode or single-mode SFP modules.
Key Features
- Compliant with IEEE 802.3 10BaseT, IEEE 802.3u 100BaseTX, IEEE 802.3ab 1000BaseT, and IEEE 802.3z 1000BaseSX/LX standards.
- Includes one 10/100/1000BaseT(X) Ethernet TP port and two 1000BaseSX/LX Gigabit Ethernet fiber ports.
- The two 1000BaseSX/LX fiber ports can support either multi-mode or single-mode SFP modules.
- The TP port supports Half/Full-Duplex, Auto-MDI/MDI-X, and Auto-Negotiation.
- Designed for use in a 19" Converter Chassis, supporting up to 16 slots with an optional redundant power supply for expanded configurations.

Application
The converter supports two primary operating modes:
- RJ-45 to SFP
- SFP to SFP (SFP modules can be either Single Mode or Multi-Mode)
Connection Diagrams:
Multi-Mode Fiber (MMF) Application (Up to 550m): Illustrates a network setup where a Gigabit Switch connects via RJ45 to a Gigabit Converter. This converter then connects via MMF fiber to another Gigabit Converter, which in turn connects via MMF fiber to a second Gigabit Switch. An alternative setup shows a Gigabit Switch with an integrated Fiber Module connecting via MMF fiber to a Gigabit Converter, which then connects via MMF fiber to another Gigabit Switch.
Single-Mode Fiber (SMF) Application (Support 10, 20, and 40km): Depicts a similar network configuration as the MMF application, but specifies the use of SMF fiber optic cables for longer distances, supporting links of 10km, 20km, and 40km between converters and switches.
Installation
DC Input & External Power Adapter
The device requires a DC input of +5VDC and 2A, supplied via an external power adapter.
The TP Port
The TP (Twisted Pair) port supports Auto-MDIX, Auto-Negotiation, and Flow Control. It is compatible with 10BaseT, 100BaseTX, and 1000SX/LX environments. The maximum cable length for Cat5, Cat5e, or Cat6 shielded/unshielded twisted-pair cables is 100 meters.
2 x SFP slots
The converter is equipped with two SFP slots, which accept both multi-mode and single-mode SFP modules.

LED Indicators
The media converter features several LED indicators to display status:
| LED | Status | Operation |
|---|---|---|
| Power (Amber) | On | Power is on |
| Copper 1G (Green) | On/Off | 1Gbps / Under 1Gbps |
| Copper Link/Act. (Green) | On/Flashing | Link/Transmitting |
| SFP1 Link/Act. (Green) | On/Flashing | Link/Transmitting |
| SFP2 Link/Act. (Green) | On/Flashing | Link/Transmitting |
LLF/LFP Function
Link Loss Forwarding (LLF) / Link Fault Pass Through (LFP) is a feature that propagates a link failure message across the network if an optical fiber link fails. This function allows system administrators to quickly identify link failures, thereby minimizing potential losses.
Notice: The SFP to SFP mode does not support the LFP function. Ensure the DIP switch is turned off in this mode.
