SPM-ETGX-PXT Industrial 10G Media Converter Application Solutions

Based on original factory hardware specifications, combined with typical industrial network scenarios, this document provides practical engineering solutions. All hardware capabilities are derived from PDF document parameters.

Solution Overview

The SPM-ETGX-PXT industrial 10G media converter solves the problems of short 10G copper cable distance (maximum 100 meters), high factory EMI interference, and unstable Ethernet transmission in high and low temperature environments. It achieves copper-to-fiber conversion, extending 10G signals through fiber optics from hundreds of meters to tens of kilometers. With IP40 rating, -40°C to +75°C wide temperature range, and redundant power supply, it is suitable for harsh scenarios such as factories, rail transit, smart campuses, and security. The device provides point-to-point media conversion, plug-and-play, without requiring complex configuration.

Key Hardware Capability Constraints (Must Be Followed in Solution Design)

1. Maximum copper cable distance on the electrical port side is 100 meters; fiber distance depends on the SFP+ optical module, up to 80km;
2. Maximum power consumption of the entire device is 5W, no PoE output;
3. Supports backward-compatible speeds from 100M-1G-2.5G-5G-10G, allowing legacy equipment and 10G core networks to interoperate;
4. Supports 16K jumbo frames, suitable for video and big data industrial data streams;
5. Supports DIN rail mounting, suitable for deployment inside industrial control cabinets.

Scenario 1: Smart Manufacturing Factory Workshop - Long-Distance Fiber Backhaul for 10G Equipment

Business Background

Machine vision inspection cameras, industrial AI gateways, and 10G industrial controllers in the production workshop are hundreds of meters away from the central equipment room. Copper network cables are subject to strong electromagnetic interference from frequency converters and motors, making it impossible to stably run 10G. The 100-meter copper cable distance limit cannot cover the required range. The temperature inside workshop control cabinets fluctuates significantly, with low temperatures in winter and high temperatures in summer.

Network Topology

Field end: Machine vision 10G equipment → Cat6A cable (<=100m) → SPM-ETGX-PXT (DIN rail mounted in workshop control cabinet) → SFP+ optical module + single-mode fiber → Equipment room end SPM-ETGX-PXT → Cat6A cable → Equipment room 10G core switch.

Solution Highlights

1. Installation: Device is mounted on the control cabinet DIN rail; two 24VDC industrial DC power supplies provide redundant power, ensuring business continuity during power failures;
2. Environment: -40°C to +75°C wide temperature range adapts to high cabinet temperatures and low winter workshop temperatures in northern regions; IP40 aluminum alloy dustproof;
3. Advantages: Fiber optics are completely immune to motor EMI interference; supports backward compatibility - if field equipment only has 2.5G/5G, the device auto-negotiates and adapts without requiring hardware replacement; supports jumbo frames for machine vision large image data streams;
4. Note: The distance between vision cameras and the converter must not exceed 100 meters; select the corresponding distance SFP+ single-mode optical module between the equipment room and workshop.

Scenario 2: Smart Campus, Large Factory 10G Network Long-Distance Extension

Business Background

Campus office buildings and outdoor AP aggregation points are more than 100 meters away from the network equipment room, requiring 10Gbps bandwidth extension to building sub-cabinets. Traditional 10G copper cables cannot reach. Outdoor cabinets experience large day-night temperature differences.

Topology

Building sub-cabinet: 10G wireless AP aggregation switch → Cat6A cable → SPM-ETGX-PXT (wall-mounted/DIN rail mounted inside outdoor IP55 cabinet) → Fiber link → Central equipment room SPM-ETGX-PXT connects to 10G core switch.

Solution Highlights

1. Device is placed inside an outdoor protective cabinet (this unit is IP40 rated and cannot be directly exposed to rain);
2. Power supply uses 12-48VDC DC, utilizing the industrial DC power supply inside the cabinet for redundant input;
3. Multiple buildings can use point-to-point paired deployment to achieve 10G uplink backhaul for each building; backward compatibility allows legacy Gigabit switches to connect, with the converter auto-negotiating speed.

Scenario 3: Large HD Security Monitoring System 10G Backhaul

Business Background

After high-point PTZ cameras and multiple 4K/8K cameras are aggregated, the aggregation switch outputs 10G uplink; monitoring points are several kilometers away from the monitoring center, requiring fiber optic transmission for high-volume video bitstreams.

Topology

Front-end monitoring aggregation switch 10G electrical port output → Cat6A cable <=100m → SPM-ETGX-PXT → SFP+ single-mode fiber → Monitoring equipment room SPM-ETGX-PXT → 10G storage/core switch.

Solution Highlights

1. Supports 16K jumbo frames, suitable for large video packet transmission;
2. Industrial wide temperature range, can be deployed in roadside and tunnel monitoring cabinets; redundant power supply reduces power outage failures;
3. Rapid fault location: Relying on the three LED indicators PWR/TP/FX on the panel, engineering personnel can quickly diagnose power, network cable, and fiber link faults on-site without logging into the device, making O&M simple;
4. Note: This device does not support PoE; camera power supply requires a front-end PoE switch to handle independently.

Scenario 4: Rail Transit / Tunnel Auxiliary Network Extension

Business Background

Tunnel and subway ground-side cabinets experience large temperature differences and complex electromagnetic environments. Some business equipment only has 10GBASE-T copper ports without SFP+ optical ports, requiring conversion to fiber for long-distance transmission.

Topology

Field business terminal (10G electrical port) → Cat6A cable → SPM-ETGX-PXT → Single-mode fiber → Control center equipment room.

Solution Highlights

1. Device operating temperature of -40°C to +75°C adapts to low winter temperatures and high summer temperatures in tunnels; enclosure grounding ensures the entire device meets IEC series industrial EMC immunity standards, resisting surge, electrostatic, and burst interference;
2. DIN rail mounting is suitable for narrow tunnel cabinets; dual DC redundant power supply improves system reliability.

General Engineering Implementation Standards (Applicable to All Scenarios)

1. Paired Use Principle: For most fiber point-to-point projects, deploy one SPM-ETGX-PXT at each end; alternatively, one end can use this device while the other end connects directly to a switch with SFP+ 10G ports.
2. SFP+ Selection: This device's SFP+ slot only supports 10G SFP+ modules, not standard Gigabit SFP modules.
   • Multi-mode within 300 meters: Select 10G-SR multi-mode SFP+;
   • 10km-80km long distance: Select corresponding distance single-mode 10G-LR/BX SFP+;
3. Cabling Standards:
   • For 10G electrical port transmission, qualified Cat6A cables must be used, with length strictly controlled within 100 meters;
   • Properly label fiber TX/RX directions; install dust caps on unused optical ports;
4. Power Supply Standards: Prioritize dual DC redundant input; reliably ground the metal enclosure to improve EMC performance; never connect AC220V directly to the device's DC terminals.
5. Fault Handling: On-site, prioritize observing LED indicators to locate faults. The device is plug-and-play with no web management interface; for special requirements, DIP switch functions support customization. Contact original manufacturer Sopto for technical support.
