Product Features
Technical Overview
This media converter handles conversion between copper Ethernet and fiber optic cabling, specifically supporting multimode fiber with SC connectors. It operates at a 1310nm wavelength, which is standard for multimode applications, and achieves a maximum distance of 2 kilometers, effectively overcoming the 100-meter limit of traditional Cat5/Cat6 copper runs.
The device is compliant with Fast Ethernet standards (10/100Base-TX), ensuring compatibility with existing network infrastructure. It requires no external power management beyond standard electrical input, simplifying deployment in both rack-mounted and standalone setups.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
The LH741-TPSCM provides a cost-effective way to leverage fiber optic benefits without overhauling entire network infrastructure. Its environmental compliance with RoHS and WEEE directives, along with TAA compliance and U.S. origin, ensures it meets regulatory standards for government and enterprise procurement.
Extended Network Reach
Converts copper to fiber to extend Fast Ethernet connections up to 2 kilometers, ideal for connecting buildings or remote network segments.
- Eliminates copper distance limitations
- Maintains signal integrity over fiber
Flexible Deployment
Supports both rack-mountable and standalone form factors, allowing integration into data centers or use as a desktop unit.
- Fits high-density enclosures
- No specialized mounting required
Deployment / Use Cases
This media converter is designed for scenarios where network extension beyond copper limits is necessary. Common applications include connecting separate buildings within a campus, linking network equipment across industrial floors, or integrating fiber backbones into existing copper-based LANs.
In educational or corporate campuses, it can bridge network segments between administrative and auxiliary buildings. For industrial settings, it enables reliable connectivity in environments with electromagnetic interference where copper may be susceptible. The rack-mountable option suits data center consolidation, while standalone use fits small office or retail deployments.

User Manual
FAQ
What does this media converter actually do?
It converts Fast Ethernet network signals from a standard copper RJ-45 connection to multimode fiber optic with an SC connector. This allows you to extend your network beyond the 100-meter limit of copper cabling, supporting distances up to 2 kilometers while maintaining 10/100 Mbps speeds.
What type of fiber optic cable is compatible?
This converter is designed for multi-mode fiber optic cables with SC connectors. It operates at a 1310nm wavelength, which is typical for multimode applications. Ensure you use multimode fiber (not single-mode) with SC terminations for proper compatibility and performance.
How far can this converter extend my network?
It supports a maximum distance of 2 kilometers (approximately 1.24 miles) over multimode fiber. This is significantly longer than the 100-meter maximum for standard Cat5/Cat6 copper Ethernet, making it suitable for connecting buildings or remote network segments.
Can I mount this in a rack?
Yes, the LH741-TPSCM is rack-mountable and can be installed in high-density rack enclosures. It also supports standalone use, giving you flexibility for deployment in data centers, network closets, or as a desktop unit depending on your space and organizational needs.
What network speeds does it support?
It supports Fast Ethernet, specifically 10/100Base-TX network technology. This means it handles both 10 Mbps and 100 Mbps Ethernet speeds, making it compatible with most legacy and modern network equipment that operates at these standard rates.
Is this product compliant with government procurement standards?
Yes, it is TAA (Trade Agreements Act) compliant and manufactured in the United States, meeting requirements for many government and institutional purchases. Additionally, it complies with RoHS and WEEE environmental directives for hazardous substance restriction and electronic waste management.
