Product Specifications

The 100BASE-FX SFP Optical Transceiver is designed for medium-range data transmission up to 2 kilometers over multimode fiber (MMF). With a compact SFP package and LC connector, this module combines reliability and convenience for various networking applications. It employs a 1310nm FP laser and PIN photodetector, making it suitable for Ethernet, telecommunications, and Fiber Channel networks. The transceiver operates with a single +3.3V power supply and supports LVPECL-compatible data input/output interfaces. Fully compliant with IEC-60825 laser safety standards and RoHS environmental standards, it meets stringent safety and environmental requirements.

This 100BASE-FX SFP transceiver is optimized for diverse operational environments, accommodating supply voltages between 3.15V and 3.45V. It performs efficiently across a commercial temperature range of 0°C to +70°C and supports industrial conditions as low as -40°C and as high as +85°C. The module consumes a maximum of 1W of power, making it an energy-efficient solution for networking needs. Its design includes low electromagnetic interference (EMI) and high electrostatic discharge (ESD) protection, ensuring stable performance in sensitive network infrastructures.

Optical performance is a highlight of this module, with a transmitter center wavelength of 1310nm and an output power range of -20dBm to -12dBm, suitable for medium-range signal transmission. The extinction ratio, between 12dB and 18dB, ensures strong signal differentiation. The receiver operates across wavelengths from 1260nm to 1620nm, with a sensitivity of -34dBm, enabling it to handle a range of optical signals while maintaining compliance with IEEE 802.3u and ANSI Fiber Channel standards for optical eye diagrams.

The transceiver’s electrical specifications further enhance its flexibility and compatibility. With a differential impedance of 100Ω, it supports input and output swing differentials suited to various host system configurations. Clear voltage thresholds for TX Disable and Rx_LOS functions enable accurate control and diagnostics, making the module highly adaptable for different network setups.

Overall, the 100BASE-FX SFP Optical Transceiver is a dependable and energy-efficient solution for medium-range optical communication. Its robust design, advanced optical and electrical characteristics, and compliance with industry standards make it a trusted choice for networking professionals.

All of our optical transceivers come with a lifetime warranty.
