Product Features
Technical Overview
This media converter implements the 1000Base-SX/LX standard over fiber and 1000Base-T over copper, ensuring compatibility with existing Gigabit Ethernet infrastructure. The LC duplex fiber port operates at 850 nm wavelength on multimode fiber, while the RJ-45 port auto-negotiates speed and duplex settings with connected copper devices.
Advanced networking features include link-loss forwarding for maintaining connectivity during fiber interruptions, remote monitoring capability for status checks, and support for both standard and jumbo frames up to 9KB for optimized data transmission. The converter requires minimal configuration and operates transparently within the network, preserving MAC addresses and VLAN tags across the conversion.
Key Product Advantages
The ET91000LC2 delivers cost-effective network extension without requiring expensive switch upgrades or complex reconfiguration. By leveraging fiber's immunity to electromagnetic interference, it enables reliable connectivity in electrically noisy environments where copper cabling would suffer performance degradation.
Deployment Flexibility
Operates as a standalone desktop unit or mounts in a rack chassis, adapting to both temporary and permanent installation scenarios.
- Standalone operation
- ETCHS2U rackmount compatible
- Desktop placement option
Future-Proof Design
The hot-swappable SFP module allows easy replacement or upgrade to different fiber specifications without replacing the entire converter unit.
- Removable SFP transceiver
- Field-replaceable optics
- Specification swapping capability
Network Optimization
Advanced features enhance network reliability and performance across the media conversion boundary.
- Link-loss forwarding
- Remote status monitoring
- Dual frame length support
Deployment / Use Cases
This fiber media converter is ideal for extending network segments between buildings, across manufacturing floors, or through areas with high electromagnetic interference. It bridges the gap where copper Ethernet reaches its 100-meter limit, providing a cost-effective alternative to installing fiber-capable switches at both ends of the connection.
Common deployment scenarios include connecting network closets across campus environments, linking industrial control systems in factory settings, extending surveillance camera networks across large facilities, and integrating fiber backbone connections with copper-based edge devices. The converter's compact size and low power consumption make it suitable for space-constrained locations like telecom closets, control panels, or equipment racks.

FAQ
What types of network connections does this media converter support?
The ET91000LC2 converts between two media types: one LC duplex multimode fiber optic connection (850 nm wavelength) and one standard RJ-45 copper Ethernet connection. It supports Gigabit Ethernet (1000 Mbps) on both interfaces, implementing 1000Base-SX/LX standards on the fiber side and 1000Base-T on the copper side for full compatibility with existing network equipment.
What is the maximum distance I can achieve with this converter?
This converter supports fiber cable runs up to 550 meters (0.55 km or approximately 0.34 miles) when using multimode fiber with 850 nm wavelength. This extends far beyond the 100-meter limitation of standard copper Ethernet, making it ideal for connecting network segments between buildings or across large facilities where direct copper connections are not feasible.
Can I use this converter in a rack-mounted installation?
Yes, the converter is designed for both desktop and rack-mounted deployment. It can operate as a standalone unit on a desktop or shelf, or it can be installed into the optional ETCHS2U rackmount chassis for centralized installation in standard 19" equipment racks. The unit includes a grounding screw for proper electrical bonding when mounted in metal racks or enclosures.
What advanced networking features does this media converter include?
Beyond basic media conversion, the ET91000LC2 includes several enterprise-grade features: link-loss forwarding maintains connectivity during fiber interruptions by disabling the corresponding copper port, remote monitoring allows status checking from network management systems, support for jumbo frames up to 9KB optimizes data transmission efficiency, and the device operates in both half-duplex and full-duplex modes for compatibility with various network configurations.
Is the fiber transceiver replaceable in this converter?
Yes, the SFP (Small Form-factor Pluggable) transceiver module is removable from the converter unit. This allows for field replacement if the optics fail, or enables swapping to a different fiber specification (such as single-mode or different wavelength) without replacing the entire converter. This modular design provides flexibility for future network changes or upgrades.
What certifications and warranty apply to this product?
The converter is TAA (Trade Agreements Act) compliant for government procurement, carries EU RoHS certification, and meets Restriction of Hazardous Substances (RoHS 2), REACH, and WEEE environmental standards. It includes a 2-year limited warranty from StarTech.com and is manufactured in Taiwan with full technical support available from the manufacturer.
