Product Features
Technical Overview
This transceiver/media converter operates at Gigabit Ethernet speeds, supporting 10/100/1000Base-TX over twisted pair and 1000Base-X over fiber optic connections. It features one RJ-45 port for copper connectivity and one SFP (Small Form-factor Pluggable) slot for fiber optic modules, allowing flexibility in fiber type and distance requirements. The SFP slot accommodates industry-standard SFP transceivers, enabling customization for specific fiber optic cable core/cladding specifications such as 50/125 µm, 62.5/125 µm, or 9/125 µm.
The device supports both multi-mode and single-mode fiber, providing versatility for short to long-distance network extensions. Multi-mode fiber is typically used for distances up to 550 meters, while single-mode fiber can extend signals over several kilometers, depending on the SFP module used. This technical flexibility ensures compatibility with existing fiber infrastructure and future network upgrades.
Key Product Advantages
The LGC135A-R3 simplifies network integration by converting between copper and fiber media without compromising speed or reliability. Its compact, rack-mountable design saves space in crowded network environments, while the included power supply and mounting hardware reduce setup time. The support for both multi-mode and single-mode fiber through the SFP slot allows network teams to tailor the solution to specific distance and bandwidth needs, whether for intra-building connections or longer campus links.
Media Flexibility
Converts RJ-45 Ethernet to fiber optic, supporting multi-mode and single-mode fibers via an SFP slot for adaptable distance and cable type options.
- Use with 50/125 µm, 62.5/125 µm, or 9/125 µm fiber
- Choose SFP modules for specific distance requirements
Deployment Ready
Includes rackmount ears and an AC power supply for immediate installation in standard 19-inch racks, ensuring a secure and organized setup.
- Pre-installed mounting options
- External power for easy replacement
Deployment / Use Cases
This media converter is ideal for extending network segments beyond the 100-meter limit of standard copper Ethernet cables. Common use cases include connecting network switches in separate buildings using fiber optic cabling, integrating fiber backbone links into copper-based access networks, and upgrading legacy copper infrastructure to support higher bandwidth over longer distances.
In data centers, it can link servers or storage devices with fiber interfaces to copper-switched networks. For industrial or campus environments, it enables reliable connectivity across harsh or electrically noisy areas where fiber's immunity to interference is advantageous. The rack-mountable form factor makes it suitable for centralized network management in racks or enclosures.
Building-to-Building Connectivity
Extend Gigabit Ethernet between facilities using single-mode fiber for distances up to several kilometers, avoiding signal degradation common with copper.
Data Center Integration
Connect fiber-equipped servers or switches to copper network segments, facilitating mixed-media environments without replacing existing infrastructure.
Physical Profile
The converter has a compact footprint with dimensions of 1.80" wide, 3.40" deep, and 0.80" high (45.72 mm x 86.36 mm x 20.32 mm), making it space-efficient in rack installations. Its lightweight design at 1.20 lb (544.31 g) allows for easy handling and mounting. The rack-mountable form factor includes ears for secure attachment to standard 19-inch rack rails, ensuring stable placement in network cabinets. The solid construction supports reliable operation in typical office or data center environments.
