Specifications
The 14.025Gbps SFP+ Optical Transceiver is a high-performance module optimized for short-range optical communication over multimode fiber (MMF) up to 100 meters. Featuring an 850nm VCSEL laser and a PIN photodiode, this transceiver supports data rates of 4.25Gbps, 8.5Gbps, and 14.025Gbps, making it ideal for applications in Fibre Channel networks. It complies with SFP+ MSA and SFF-8472 standards, ensuring seamless integration with existing networking systems. The module’s hot-pluggable design and duplex LC connector simplify deployment and maintenance.
Operating on a single +3.3V power supply, the transceiver consumes less than 1W of power, making it energy-efficient. It is designed for commercial environments with an operating temperature range of 0°C to +70°C. Additionally, its compatibility with RoHS regulations underscores its environmentally responsible design. Integrated digital diagnostic monitoring provides real-time tracking of critical parameters like temperature, voltage, bias current, and optical power, ensuring reliability and facilitating proactive maintenance.
Optically, the transmitter delivers an average output power ranging from -7.8dBm to -0.5dBm with a center wavelength of 850nm. The extinction ratio is maintained at 3.0dB for clear signal transmission. The receiver offers a sensitivity of -10.5dBm and operates across a wavelength range of 840nm to 860nm. Loss of Signal (LOS) functionality enhances link diagnostics, ensuring consistent performance and fault detection.
Electrically, the transceiver supports a differential impedance of 100Ω, with input swing differentials from 180mV to 950mV. Advanced timing parameters, such as a Tx Disable Assert Time of 10µs and Tx Fault Assert Time of 100µs, ensure quick and reliable transitions in network operations. Internal AC-coupled inputs and outputs enhance integration with host systems.
In summary, the 14.025Gbps SFP+ Optical Transceiver is a reliable and efficient solution for high-speed data communication over short distances. Its robust design, compliance with industry standards, and advanced diagnostic features make it an essential component for modern data transmission infrastructures.
This hot-pluggable module supports data rates up to 14.025 Gbps for 16G Fibre Channel, and is backward compatible with 8.5 Gbps (8G) and 4.25 Gbps (4G).
