16G FC-LWL SFP+ 20km SMF Transceiver: 16GFC-SFP-20

Our EDGEOPTIC 16GFC-SFP-20 is a multi-vendor compatible 16G Fiber Channel LWL (Long Wavelength) SFP+ dual-fiber optical module designed for extended-reach storage area network applications operating over single-mode fiber cabling. The 16GFC-SFP-20 module operates at 1310nm 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-LWL SFP+ transceiver utilizes DFB (Distributed Feedback) laser technology for transmission and PIN photodiode for receiving. The transceiver ensures a 10 dB guaranteed optical link budget, providing substantial margin for reliable long-distance connectivity. Over standard single-mode fiber (SMF OS1/OS2), the transceiver reliably reaches distances up to 20 kilometers, making it ideal for metropolitan area SAN extensions and disaster recovery implementations. 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-20 compatible 16G FC-LWL 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-LWL 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 enhanced optical output power range from -2 to 3 dBm combined with -12 dBm receiver sensitivity delivers the extended 20-kilometer reach capability. The receiver features a wide wavelength bandwidth of 110nm (1260-1370nm) ensuring compatibility with various optical sources 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 metropolitan area SAN implementations, disaster recovery site connections, campus-to-campus storage network links, and remote data center interconnections. The 20-kilometer reach enables cost-effective extended-distance Fiber Channel connectivity without requiring optical amplification or regeneration equipment. 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 bandwidth-intensive storage applications. 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.
