Name: 10/100M Ethernet over E1 Converter 1 FE to 8E1 Interface Converter
Brand: Miray
SKU: MR-1FE8E1
Rating: 5 (1 reviews)

This interface converter is based on FPGA, using reverse direction multiplexing technology to bundle for multiple E1 circuits to transmit the Ethernet data of 100BASE-TX. It can realize 1-8E1 channel to convert between Ethernet optical interface. This device can transmit the transceiver signal point to point to Ethernet optical interface to make E1 channels interconnected with Ethernet optical interface. Different with general remote network bridge, this device can support 1-8Channel E1 channel configuration, can automatically detect the number of E1 and select the E1 available. It allows E1 lines transmission time delay difference. delay difference.

Purpose-Built Ethernet Transport over 1–8 E1 Links
The 10/100M Ethernet over E1 Converter is designed for professional deployments that need to carry Fast Ethernet traffic across existing E1 infrastructure without replacing the underlying transmission network. By converting 1 FE interface to up to 8 E1 channels and supporting Ethernet optical interface interconnection, it gives operators, integrators, and telecom-focused buyers a practical way to extend ethernet switch and network switch services into legacy or bandwidth-constrained environments. For projects comparing solutions from industrial ethernet switch manufacturers, top network switch manufacturers, and optical transceiver manufacturers, this converter serves as a focused transport device that bridges Ethernet access with traditional E1 resources while preserving transparent data transmission and point-to-point link integrity.

FPGA Architecture with Dynamic E1 Aggregation and Traffic Control
Built on an FPGA platform with reverse multiplexing technology, the unit bundles multiple E1 circuits to transmit 100BASE-TX Ethernet data and supports flexible 1–8 E1 channel configuration based on actual line availability. It can automatically detect the number of connected E1 lines, select usable E1 channels, and tolerate transmission delay differences between lines, which is essential for operational stability in carrier and industrial communication systems. The Ethernet optical interface supports 100BASE-FX and VLAN protocol, while dynamic MAC address learning for up to 4,096 entries and local data frame filtering improve traffic handling efficiency. Additional features such as local and remote device reset, configurable CRC automatic alarm thresholds for isolating poor-quality transmission lines, single-channel line rates of 1984 Kbit/s, and aggregate bandwidth up to 7936 Kbit/s across four channels provide the technical evidence buyers expect when evaluating integration alongside a transceiver, sfp module, or managed transport edge.

Well-Suited for Carrier Access, Utility Networks, and Legacy System Integration
This converter is well-suited for telecom access expansion, utility communication networks, transportation control systems, and industrial sites where E1 circuits remain available but Ethernet service delivery is required at the edge. It helps organizations protect existing infrastructure investments while extending optical or copper Ethernet connectivity to remote nodes, aggregation points, and specialized field equipment. In practical deployments, it can complement broader architectures that may also include a poe switch, optical uplinks, and standard switching equipment, enabling disciplined network design rather than forcing a full hardware refresh. For B2B buyers prioritizing transmission reliability, flexible channel allocation, and straightforward interconnection between E1 and Ethernet domains, this converter offers a stable and efficient option for long-life network modernization.

Key Advantages

Flexible E1 Aggregation for Stable Ethernet Transport
This converter is designed to transmit Fast Ethernet traffic over 1 to 8 E1 lines, which gives integrators a practical way to build data links on existing E1 infrastructure without replacing the whole network switch environment. Its FPGA-based reverse multiplexing structure can automatically detect available E1 channels and support bandwidth scaling as lines are added, which helps maintain stable service delivery in projects where line resources vary by site. For buyers comparing industrial ethernet switch manufacturers or planning links between legacy transmission systems and modern Ethernet equipment, this structure offers a reliable method to extend data communication while preserving predictable performance.

Practical Deployment and Maintenance Efficiency
The device supports local and remote reset, dynamic MAC address handling, VLAN protocol support, and configurable CRC alarm thresholds, all of which improve daily operation and fault isolation. These functions matter in industrial and carrier-side environments because maintenance teams need to identify poor quality transmission quickly and keep downtime under control without repeated on-site intervention. When used alongside equipment from top network switch manufacturers, or connected through an optical interface to systems associated with an sfp module or transceiver deployment plan, it provides a stable and practical conversion layer that reduces management complexity.

Use Scenarios

Utility and Industrial Remote Site Interconnection
In substations, transport cabinets, or industrial control sites where legacy E1 lines are already deployed but Ethernet access is required for monitoring and control systems, operators often need to carry data traffic without rebuilding the transmission path. This converter acts as the bridge between Fast Ethernet equipment and multiple E1 circuits, allowing existing links to support modern IP-based communication in a stable way. It is well-suited to this environment because it tolerates multi-E1 transmission structures, supports optical Ethernet interconnection, and helps maintenance teams manage service continuity where reliable long-distance access is essential.

Carrier Access and Optical Network Extension
In telecom access rooms or enterprise edge locations, users may need to connect Ethernet devices across E1 resources to reach optical aggregation equipment while keeping bandwidth usage practical and controlled. In this scenario, the converter serves as a point-to-point transport device between Ethernet electrical or optical interfaces and bundled E1 channels, making it useful for linking systems planned around an ethernet switch, poe switch, or equipment sourced from optical transceiver manufacturers. It fits this role because it supports VLAN-aware transport, automatic E1 channel selection, and stable operation across mixed legacy and optical transmission networks.

FAQ

Q1. Can this converter integrate with our existing Ethernet and E1 transmission infrastructure?
Yes, we support integration where your network requires conversion between 1-8 E1 channels and Ethernet optical interface. Our unit carries 100BASE-TX data through bundled E1 circuits and supports 100BASE-FX, making it practical for mixed legacy and network switch environments.

Q2. How does the device handle variable E1 availability in field deployments?
The unit supports 1-8 channel E1 configuration and can automatically detect the number of E1 lines in service, then select available channels for transmission. We designed it to accommodate delay differences between E1 lines, which helps maintain stable point-to-point transport in carrier networks.

Q3. Does this product support VLAN operation and MAC address management?
Yes, our converter supports VLAN protocol on the Ethernet interface and includes dynamic Ethernet MAC address handling for up to 4,096 entries. We also provide local data frame filtering, which is useful when the device is deployed alongside a ethernet switch or other managed transport equipment.

Q4. What throughput can we expect when configuring multiple E1 channels?
Single-channel line rate is 1984 Kbit/s, while a 4-channel configuration reaches up to 7936 Kbit/s based on the stated specifications. Our equipment uses reverse multiplexing technology to bundle multiple E1 circuits, so it is well-suited for structured bandwidth expansion without replacing upstream transceiver links.

Q5. What maintenance or remote management functions are available for operation teams?
Reset capability is available for both local and remote devices, which helps our customers simplify fault handling during deployment and maintenance. The unit also supports CRC automatic alarm threshold settings to isolate poor-quality transmission lines, a practical feature for teams working with optical transport and optical transceiver manufacturers.
