16G Fibre Channel DWDM SFP+ C-Band 40km Single-Mode Optical Transceiver

The 16G Fibre Channel DWDM SFP+ C-Band 40km Optical Transceiver is a long-reach optical module designed for Fibre Channel storage networks and high-capacity optical infrastructure. Supporting 4.25G, 8.5G, and 16G Fibre Channel data rates, it provides transmission distances of up to 40km over single-mode fiber. A cooled C-band DWDM EML laser is paired with a PIN photodiode and integrated TIA receiver to deliver stable wavelength performance and reliable optical signal reception for extended-distance DWDM links.

Built in a hot-pluggable SFP+ form factor, the transceiver features a Duplex LC optical interface and operates from a single +3.3V power supply. Its SFF-8472-compliant monitoring interface enables compatible host equipment to access real-time diagnostic information, while SFP+ MSA compatibility and Class I laser safety support facilitate integration into Fibre Channel switches, storage systems, data center networks, and long-distance DWDM infrastructure.

FiberMania offers OEM and customized manufacturing services for Fibre Channel DWDM SFP+ transceivers. Depending on project requirements, customization can cover DWDM wavelength or channel selection, host equipment compatibility, EEPROM coding, diagnostic parameters, product labeling, housing markings, packaging, and other project-specific configurations.

For applications involving specific Fibre Channel switches, storage platforms, or DWDM equipment, customers can provide the target equipment model and network requirements for compatibility evaluation. Sample testing can be supported before volume production to help verify optical, electrical, and management compatibility.

Q1. What is the main benefit of combining Fibre Channel with DWDM?

DWDM allows multiple wavelength channels to share the same fiber infrastructure, which can increase the utilization of existing fiber routes. For Fibre Channel networks, this can be useful when extending storage connectivity between data centers or remote facilities without deploying a separate fiber pair for every connection.

Q2. What does the C-band designation indicate?

C-band refers to the optical wavelength region commonly used for dense wavelength-division multiplexing. C-band DWDM provides a large number of closely spaced optical channels, making it suitable for high-capacity optical transport and long-distance network applications.

Q3. Is the 40km transmission distance guaranteed in every installation?

No. The 40km rating represents the designed maximum reach under suitable link conditions. Actual performance depends on fiber attenuation, connector and splice losses, DWDM MUX/DEMUX insertion loss, optical power budget, and other link characteristics. A complete optical budget should be calculated for deployment planning.

Q4. What information can compatible equipment obtain through SFF-8472?

SFF-8472 provides a standardized interface for digital diagnostic monitoring. Depending on the implementation, compatible host equipment can access module operating information such as temperature, supply voltage, and optical operating parameters for monitoring and maintenance.

Q5. Can the transceiver be used with a DWDM MUX/DEMUX?

Yes. The module is intended for C-band DWDM applications and can be integrated with compatible DWDM MUX/DEMUX equipment. The transceiver’s wavelength or channel must match the corresponding optical channel of the DWDM system.

Q6. Is this module suitable for all 16G Fibre Channel equipment?

The module supports common Fibre Channel rates including 4.25G, 8.5G, and 16G, but host compatibility should still be verified. Some Fibre Channel switches and storage platforms may require specific EEPROM coding or approved transceiver configurations.
