1. FOC-TRX Series Core Model List (With Product Descriptions)

2. Quick Interpretation of FOC-TRX Series Model Naming Rules

Mastering the naming logic of FOC-TRX series models can help you quickly identify the core parameters and applicable scenarios of the product:

1. Series Prefix: FOC-TRX refers to the optical transceiver module series, dedicated to optical-electric signal conversion in industrial communication systems.
2. Package Type:
   • SFP: Small Form-factor Pluggable, a compact hot-swappable package, compatible with mainstream industrial switches and communication equipment;
   • SFP+: Enhanced SFP package, supporting higher transmission rates up to 10Gbps, suitable for high-bandwidth communication scenarios.
3. Transmission Rate: 1G/10G represents the core transmission rate of the module, 1Gbps for medium-bandwidth communication, 10Gbps for high-bandwidth data transmission.
4. Transmission Specification:
   • SX: Short-distance transmission, typically used with multi-mode optical fibers, suitable for short-distance communication within 500m;
   • LX: Long-distance transmission, compatible with single-mode/multi-mode optical fibers, suitable for medium and long-distance communication within 10km;
   • LR: Long-reach transmission, dedicated to single-mode optical fibers, supporting long-distance communication over 10km.
5. Temperature Grade:
   • IT: Industrial Temperature Grade, adapting to the temperature range of -40°C to +85°C, suitable for most industrial field environments;
   • ET: Extended Temperature Grade, with a wider temperature adaptation range, suitable for extreme temperature scenarios such as high-altitude and polar industrial sites.

3. Core Advantages of Phoenix FOC-TRX Series Optical Modules

1. Diversified Rate Coverage: Supports 1Gbps and 10Gbps two core transmission rates, meeting the communication needs of both conventional industrial Ethernet and high-bandwidth data transmission systems.
2. Flexible Transmission Distance: Covers SX short-distance, LX medium-long distance and LR long-distance transmission specifications, matching different optical fiber types and communication distance requirements.
3. Wide Temperature Adaptation: Provides IT industrial temperature and ET extended temperature two grades, with strong adaptability to harsh industrial environments such as high temperature, low temperature and large temperature difference.
4. Hot-swappable Compatibility: Adopts standard SFP/SFP+ hot-swappable package, compatible with mainstream industrial switches, routers and communication equipment, realizing quick replacement without power-off.
5. Stable Signal Transmission: With low bit error rate and strong anti-interference ability, it can ensure stable data transmission in industrial environments with strong electromagnetic interference such as workshops and factories.

4. Product Selection Suggestions

1. Rate Matching First: Determine the required transmission rate according to the bandwidth demand of the communication system, select 1Gbps models for conventional industrial Ethernet, and 10Gbps SFP+ models for high-bandwidth scenarios such as large-scale video monitoring and data acquisition.
2. Transmission Distance Selection: Choose SX specification modules for short-distance communication within 500m (matching multi-mode optical fibers); select LX specification modules for medium and long-distance communication within 10km; adopt LR specification modules for long-distance communication over 10km (matching single-mode optical fibers).
3. Temperature Grade Selection: Select IT grade modules for general industrial field environments; choose ET grade modules for extreme temperature scenarios such as high-altitude, cold storage and outdoor exposed sites.
4. Compatibility Confirmation: Confirm that the selected module is compatible with the optical fiber type (single-mode/multi-mode) and communication equipment interface of the site to ensure smooth access to the communication system.
