1. PRODUCT OVERVIEW
The FTL‑1218H‑MMC is an industrial‑grade Ethernet‑to‑fiber media converter designed and manufactured by Sunix. It carries the same designation for both product name and article number. The device belongs to Sunix’s FTL‑1218H Series of Ethernet media converters and is engineered for converting 10/100Base‑TX Ethernet signals to 100Base‑FX fiber using multi‑mode optical transmission. It supports SC optical connectors, industrial voltage ranges, DIN‑rail mounting, and extended environmental durability. It is built to serve as a robust distance‑extension and electrical‑isolation solution for industrial networking environments where immunity, reliability, and stable data transmission are essential.

2. KEY FEATURES

4. FUNCTIONALITY
The FTL‑1218H‑MMC functions as a transparent Layer‑1 media converter, enabling Ethernet signals transmitted over copper to be carried over fiber for longer distances and improved immunity to electromagnetic disturbances. It converts electrical Ethernet frames from 10/100 Mbps copper links into optical 100Base‑FX signals.

Use cases include:
• Industrial automation networks requiring long‑distance communication beyond copper cable limits.
• Electrically noisy environments where fiber provides superior EMI immunity and galvanic isolation.
• Infrastructure sites such as transportation systems, power stations, and manufacturing lines.
• Applications requiring robust, redundant power operation and DIN‑rail installation.
• SC‑based multi‑mode fiber networks or mixed copper‑fiber distribution systems.

Compatibility:
• Compatible with standard 10/100Base‑TX Ethernet devices, switches, PLCs, SCADA systems, data acquisition equipment, and fiber infrastructure using SC multi‑mode connectors.
• Designed for integration into Sunix and multi‑vendor fiber‑based industrial network topologies.

5. COMPONENTS AND ACCESSORIES
Included components typically consist of the converter unit itself, a DIN‑rail mounting bracket, and terminal block connectors. Additionally:
• Fiber port: 1x SC connector for 100Base‑FX.
• Copper port: 1x RJ45 connector supporting auto‑negotiation at 10/100 Mbps.
• Power connectors: 5‑pin removable terminal block; DC jack for redundant input.
• Alarm interface: 1 configurable relay output for event signaling (such as link fault or power failure).
Optional accessories may include fiber cables (multi‑mode 50/125 µm), external power supplies, wall‑mount brackets, and alternative SC/ST fiber connectors depending on customer request.

6. INSTALLATION AND SETUP
The FTL‑1218H‑MMC is designed for industrial cabinet and field deployment environments.
Installation steps include:
• Mounting device on DIN‑rail or wall‑mount bracket.
• Connecting 12–48 VDC power input through the terminal block or using a 12 VDC jack for redundancy.
• Attaching multi‑mode fiber cable with SC connector to the fiber port.
• Connecting copper Ethernet cable to RJ45 port.
• Configuring alarm relay output for network monitoring or event response if required.

No software configuration is required; the device performs automatic link negotiation and optical conversion. Installation is plug‑and‑play with minimal setup.

7. PERFORMANCE AND CAPABILITIES
• Ethernet speeds: Supports 10 Mbps and 100 Mbps copper Ethernet.
