Product Features
Technical Overview
This media converter operates at Fast Ethernet speeds (100 Mbps) and supports both 10/100Base-TX on the copper side and 100Base-FX on the fiber side. It features auto-negotiation and auto MDI/MDIX on the RJ-45 port for plug-and-play connectivity, eliminating the need for crossover cables. The fiber port includes Far End Fault detection to alert network administrators of link issues, enhancing troubleshooting capabilities. With a 2K MAC address table and support for 10K byte jumbo packets, it efficiently manages network traffic in mixed-media environments.
The device uses a 1310 nm wavelength laser optimized for multi-mode fiber with a core/cladding specification of 62.5/125 µm. This wavelength provides reliable performance over distances up to 2 kilometers, sufficient for most intra-building or short-campus runs. Each port includes Link/Activity LEDs for real-time status monitoring, and the Smart MissingLink feature helps maintain network stability by managing link loss scenarios.
Key Product Advantages
The MMC200/ST converter excels in environments where extending copper networks with fiber is required, offering a cost-effective solution for upgrading legacy infrastructure without replacing entire cabling systems. Its dual media conversion—both speed and media type—ensures compatibility between different network segments, reducing integration complexity. The compact design and flexible mounting options make it ideal for deployment in telecom closets, industrial control panels, or any location where space is limited.
Reliable Performance
Store-and-forward switching and transparent VLAN handling maintain data integrity across mixed media, while Far End Fault detection on the fiber port provides early warning of connectivity issues.
- 2K MAC address table
- IEEE 802.1Q packet transparency
- 10K jumbo packet support
Easy Deployment
Auto-negotiation and auto MDI/MDIX on the copper port simplify installation, and the included AC power supply ensures quick setup without additional components.
- Plug-and-play connectivity
- Wall or rack mounting
- Link/Activity LEDs per port
Deployment / Use Cases
This media converter is commonly used to extend network connections beyond the 100-meter limit of copper cabling by converting to fiber optic runs. It is ideal for connecting buildings within a campus, linking floors in multi-story offices, or integrating fiber backbones into copper-based access networks. The 2 km distance support makes it suitable for medium-range applications where direct copper connections are impractical due to distance or electromagnetic interference.
In industrial settings, the converter can bridge control systems across manufacturing floors, where fiber's immunity to electrical noise ensures reliable data transmission. For educational or healthcare facilities, it enables network expansion to remote wings or annex buildings without sacrificing performance. The TAA compliance and Singapore origin make it a viable option for government or regulated projects requiring specific sourcing standards.
Campus Network Extension
Connect separate buildings with fiber for longer reach and better signal integrity, using the RJ-45 port to interface with existing copper switches or routers.
Industrial Connectivity
Deploy in factories or warehouses to link Ethernet devices across noisy environments, leveraging fiber's resistance to interference for stable control network operations.
Physical Profile
The converter measures 0.86" (21.84 mm) in height, 2.16" (54.86 mm) in width, and 4" (101.60 mm) in depth, with an approximate weight of 6 oz (170.10 g). This compact footprint allows installation in tight spaces, such as wall-mounted enclosures or standard 19-inch rack shelves using optional mounting hardware. The lightweight design simplifies handling during deployment, and the sturdy construction ensures durability in varied operating conditions.
