Allied Telesis AT-MMC2000LX/LC – Gigabit Copper to Single-Mode Fibre Media Converter | AT-MMC2000 Series
The Allied Telesis AT-MMC2000LX/LC is a standalone gigabit media converter designed to seamlessly bridge 10/100/1000BASE-T copper networks with 1000BASE-LX single-mode fibre infrastructure. Purpose-built for enterprise and industrial environments where long-distance, high-reliability fibre links are required, this converter enables network engineers to extend Ethernet segments up to 10 km over LC-terminated single-mode fibre without signal degradation.
As a trusted component in the AT-MMC2000 product family, the AT-MMC2000LX/LC is widely deployed in manufacturing plants, utility substations, campus backbones, and data centre interconnects where copper-to-fibre migration must be transparent, non-disruptive, and standards-compliant.

Proven Application Environments
- Industrial Automation: Connects PLC/DCS copper Ethernet ports to fibre backbone rings in factory floors, eliminating EMI interference over long cable runs.
- Campus & Enterprise Networks: Extends inter-building Gigabit links up to 10 km without repeaters or additional switching hardware.
- Utility & Energy Infrastructure: Deployed in substations and power distribution control rooms where copper-to-fibre isolation is a safety and reliability requirement.
- Data Centre Interconnect: Bridges legacy copper server ports to fibre uplinks in structured cabling migrations.
- Surveillance & Security Systems: Supports IP camera backhaul over existing single-mode fibre plant.
- Transportation & Logistics: Used in rail, port, and airport control networks requiring deterministic gigabit throughput over extended distances.
Engineering Advantages
- True Plug-and-Play: No software, drivers, or configuration required — auto-negotiation handles speed and duplex on both ports automatically.
- Auto-MDI/MDIX: Eliminates the need for crossover cables on the copper side; connects directly to switches, routers, or end devices.
- Chassis-Compatible: Slots into the Allied Telesis AT-MCR12 or AT-MCR2 chassis for centralized, rack-mounted multi-converter deployments with shared power.
- Low Latency: Store-and-forward architecture with sub-microsecond conversion delay — transparent to time-sensitive industrial protocols.
- RoHS Compliant: Meets EU Directive 2011/65/EU for hazardous substance restrictions, suitable for global procurement.
- Compact Form Factor: Desktop or DIN-rail mountable (with optional bracket), minimizing panel space in control cabinets.
System Architecture & Signal Flow
The AT-MMC2000LX/LC operates as a transparent Layer 1 media converter. Signal flow is as follows:
- Copper Ingress: 10/100/1000BASE-T frames arrive on the RJ-45 port; the integrated PHY performs auto-negotiation and clock recovery.
- Rate Adaptation: Internal switching fabric buffers and adapts frame timing between copper and fibre clock domains.
- Optical Transmission: Frames are serialized and transmitted at 1000BASE-LX (1310 nm) over the LC duplex fibre port at up to 10 km.
- Receive Path: Incoming optical signals are deserialized, re-clocked, and forwarded to the copper PHY — fully bidirectional and simultaneous (full duplex).
The converter is fully transparent to VLANs, QoS markings, and jumbo frames (up to 1536 bytes), making it compatible with all upstream switching and routing infrastructure.

Technical FAQ
Q: Is the AT-MMC2000LX/LC compatible with third-party switches?
A: Yes. It is fully IEEE 802.3z compliant and interoperates with any standards-compliant Gigabit Ethernet switch or router on both the copper and fibre sides.
Q: Can it be used with multi-mode fibre?
A: No. The LX/LC variant is designed for single-mode fibre (SMF) at 1310 nm. For multi-mode fibre, refer to the AT-MMC2000/SC or AT-MMC2000ST variants.
Q: Does it support PoE pass-through?
A: No. The AT-MMC2000LX/LC does not support Power over Ethernet (PoE) on either port.
Q: What is the maximum cable distance on the copper side?
A: Up to 100 m on Cat5e or better UTP/STP cabling, per IEEE 802.3ab specification.
Q: Can multiple units be installed in a chassis?
A: Yes. The AT-MMC2000LX/LC is compatible with the Allied Telesis AT-MCR12 (12-slot) and AT-MCR2 (2-slot) media converter chassis for centralized rack deployment.
Q: Is a fibre patch cord included?
A: Availability varies by unit sourcing. Please confirm with Konmask.com at time of order. LC duplex single-mode patch cords are available separately.
