Product Overview
The OPTONE 5-Port Fast Ethernet to Fiber Media Converter / Switch (OPT-105 Series) is a compact, high-performance unmanaged networking device designed to bridge multiple copper Ethernet devices over long-distance fiber optic links. Equipped with four 10/100Base-TX RJ45 ports and one 100Base-FX fiber port, this versatile unit allows up to four local wired devices to share a single fiber uplink seamlessly.
Engineered for reliable operation in harsh or quiet environments, the OPT-105 series features a fanless natural cooling design and support for 2K-byte jumbo frames. Available in a wide variety of configurations—including multi-mode, single-mode, Bi-Directional (WDM single-fiber), and a flexible SFP slot variant—it delivers unmatched flexibility for industrial security, CCTV surveillance, and enterprise edge extensions.
Key Features & Benefits
Compact 5-Port Hybrid Design: Combines 4 x 10/100M RJ45 ports for local device connections with 1 x 100M fiber port for long-distance uplinks.
Flexible Optical Configurations: Available with fixed connectors (SC, ST, or FC) for Multi-Mode, Single-Mode, Bi-Directional (WDM), or an SFP slot option (OPT-105) for ultimate modularity.
Long-Distance Reach: Effectively extends network boundaries from 2km (Multi-mode) all the way up to 120km (Single-mode) over fiber optic infrastructure.
Fanless Natural Cooling: Operates completely silently with a reliable fanless thermal design, ensuring high stability and lower maintenance in enclosed or noise-sensitive environments.
Jumbo Frame Support: Supports up to 2K-byte jumbo frames, optimizing packet processing efficiency for security and data transmissions.
Plug-and-Play Simplicity: Fully unmanaged with auto-negotiation, auto-MDI/MDIX crossover, and dynamic LED indicators for instant, zero-configuration deployment.

Frequently Asked Questions (FAQ)
Q1: What is the difference between standard single-mode models and Bi-Directional (WDM) models like the OPT-105W25?
Standard single-mode models require two fiber cores (one for transmitting, one for receiving). Bi-Directional WDM models transmit and receive data over a single fiber core using different wavelengths (e.g., 1310nm and 1550nm), cutting fiber cabling costs in half.
Q2: Should I choose a fixed optical connector model or the OPT-105 SFP model?
Choose fixed connector models (SC/ST/FC) if you have a pre-determined fiber cable type and distance and want a ready-to-use solution out of the box. Choose the OPT-105 SFP model if you prefer modular flexibility, allowing you to swap out 155M SFP transceivers depending on changing network distance requirements.
Q3: Does the OPT-105 series require any software setup or configuration?
No. The entire OPT-105 series is fully unmanaged with true plug-and-play operation. It automatically negotiates port speeds, duplex modes, and cable crossovers without requiring any IP addresses or software management.
