16G FC DWDM SFP+ 40km Transceiver: DWDM-16GFC-SFP-40

Our EDGEOPTIC DWDM-16GFC-SFP-40 is a multi-vendor compatible 16G Fiber Channel DWDM SFP+ dual-fiber optical module designed for high-density wavelength-division multiplexed storage area network applications operating over single-mode fiber cabling. The DWDM-16GFC-SFP-40 module operates on ITU-T G.694.1 C-Band channels 17 through 61 with 100 GHz spacing, supporting 45 DWDM channels for transmission while the receiver accommodates both 50 and 100 GHz channel spacing across the C-Band spectrum. The module provides 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 DWDM 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 robust margin for extended-reach DWDM deployments. Over standard single-mode fiber (SMF OS1/OS2), the transceiver reliably reaches distances up to 40 kilometers in DWDM systems. 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.

DWDM-16GFC-SFP-40 compatible 16G FC DWDM 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 DWDM 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) and ITU-T G.694.1 DWDM grid specifications ensuring full protocol compatibility across 4G, 8G, 10G, and 16G Fiber Channel speeds. The EML laser technology with narrow 100 GHz (0.8nm) spectral width ensures minimal crosstalk in dense wavelength environments while providing superior chromatic dispersion tolerance for 40-kilometer transmission. The enhanced optical output power range from -1 to 3 dBm combined with -14 dBm receiver sensitivity delivers consistent performance across all C-Band channels. The wide receiver wavelength bandwidth from 1260 to 1620nm accommodates flexible channel assignment and supports both 50 GHz and 100 GHz channel plans. 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 DWDM SFP+ transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards.

Typical applications include high-density metropolitan and regional SAN implementations, long-distance data center interconnect solutions, service provider storage networks, and enterprise SAN extension over leased dark fiber or DWDM infrastructure. The DWDM capability enables up to 45 independent Fiber Channel links over a single fiber pair when combined with appropriate DWDM multiplexers, dramatically increasing fiber capacity. The 40-kilometer reach combined with 100 GHz channel spacing provides optimal balance between distance, channel density, and system performance. The multi-rate capability accommodates mixed-speed SAN deployments while maximizing bandwidth utilization in fiber-constrained environments across extended distances. 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 at specified DWDM wavelengths, spectral width verification, connector cleanliness tests, and SFP+ transceiver EEPROM memory data validation tests.
