16G FC-ELW SFP+ 40km SMF Transceiver: 16GFC-SFP-40

Our EDGEOPTIC 16GFC-SFP-40 is a multi-vendor compatible 16G Fiber Channel ELW (Extra Long Wavelength) SFP+ dual-fiber optical module designed for ultra-long-reach storage area network applications operating over single-mode fiber cabling. The 16GFC-SFP-40 module operates at 1550nm wavelength for both transmission and reception, with multi-rate data support from 4.25 to 14.025 Gbps enabling compatibility with 4G, 8G, 10G, and 16G Fiber Channel protocols. Our 16G FC-ELW SFP+ transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and PIN photodiode for receiving. The transceiver ensures a 13 dB guaranteed optical link budget, providing exceptional margin for ultra-long-distance connectivity. Over standard single-mode fiber (SMF OS1/OS2), the transceiver reliably reaches distances up to 40 kilometers, making it ideal for metropolitan and regional SAN extensions without intermediate amplification. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry.

16GFC-SFP-40 compatible 16G FC-ELW module is hot-pluggable SFP+ with duplex LC/UPC connectors as an optical interface. The electrical interface conforms to SFF-8431 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP+ host systems supporting multiple vendor equipment platforms. Our 16G FC-ELW SFP+ transceiver can be encoded to be compatible and successfully operate in different 80+ brands of storage and networking equipment. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible EEPROM interface and enables proactive monitoring of transceiver operational parameters. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in controlled data center environments.

Standards compliance includes Fibre Channel 16GFC Physical Interface specifications (FC-PI-5 Rev 6.00) ensuring full protocol compatibility across 4G, 8G, 10G, and 16G Fiber Channel speeds. The EML laser technology provides superior chromatic dispersion tolerance essential for 40-kilometer transmission at high data rates. The enhanced optical output power range from -2 to 3 dBm combined with -14 dBm receiver sensitivity delivers the extended reach capability. The receiver features an ultra-wide wavelength bandwidth of 340nm (1260-1600nm) ensuring broad compatibility while maintaining signal integrity. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility. Our 16G FC SFP+ transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards.

Typical applications include regional SAN implementations, disaster recovery site connections across metropolitan areas, inter-city data center interconnections, and remote backup facility links. The 40-kilometer reach enables cost-effective ultra-long-distance Fiber Channel connectivity without requiring optical amplification, regeneration equipment, or intermediate repeater stations. The multi-rate capability accommodates mixed-speed SAN deployments, allowing seamless integration with legacy 4G and 8G Fiber Channel equipment while supporting modern 16G speeds for maximum throughput in geographically distributed storage architectures. Because our focus is providing top quality service, we perform rigorous quality checks before delivery of our products. As a result, we conduct optical parameter measurements, connector cleanliness tests, and SFP+ transceiver EEPROM memory data validation tests.
