Key Features

Optimized 1G Data Center Connectivity
Designed with low power consumption, these SFP transceivers offer a cost-effective solution for Gigabit Ethernet applications in modern data centers.

Proven Interoperability
Each module is thoroughly tested in target host devices to ensure full compatibility and seamless operation across supported switches.

Core Capabilities

• Hot-swappable SFP (MSA compliant)
• Digital Optical Monitoring (DOM) support
• Class 1 FDA laser safety certified

Comprehensive Testing for Maximum Reliability

Each transceiver undergoes strict validation using advanced testing equipment to ensure high performance and dependability:

• Optical Spectrum Testing
• Zero Packet Loss & CRC Validation
• Eye Pattern Analysis (Mask Margin > 20%)
• Bit Error Rate Testing (BER: 1E-12)
• Temperature Stability Testing (0°C to 70°C)

Seamless Network Integration

With support for real-time reconfiguration via cable BOX, these transceivers enable multi-vendor compatibility, reduce inventory requirements, and enhance deployment flexibility.

Reliable Performance Assurance

Professional testing verifies both hardware and software compatibility, ensuring stable performance across connectivity, BER, and key operational parameters. Detailed reports are available for review.

The module can connect to both devices normally, and the device port status is up.

Performs diagnostic tests on transceiver modules to view the various parameters of the transceiver module, such as temperature, voltage, transmission power, and so on.
