FiberMania provides OEM and customized manufacturing services for Fibre Channel SFP+ DWDM transceivers. Customers can specify the required DWDM channel, host equipment compatibility, EEPROM coding, diagnostic parameters, product labeling, housing identification, packaging, and other project-specific requirements.

Q1. What does C17-C61 mean for this DWDM transceiver?

C17-C61 identifies the supported DWDM channel range within the C-band based on the applicable ITU wavelength grid. The exact optical wavelength is determined by the selected channel, allowing the transceiver to be integrated into a specific DWDM channel plan.

Q2. Can this module be used in a DWDM system with a MUX/DEMUX?

Yes. The transceiver is designed for wavelength-specific DWDM applications and can be used with compatible DWDM MUX/DEMUX equipment. The selected transceiver channel must correspond to the intended MUX/DEMUX channel, and the complete optical link budget should be evaluated before deployment.

Q3. Why does the module use a cooled EML laser?

A cooled EML laser provides improved wavelength and optical stability across temperature variations. This characteristic is valuable in DWDM systems, where precise wavelength control is important for maintaining reliable operation within closely spaced optical channels.

Q4. What is the purpose of the PIN photodiode and TIA receiver?

The PIN photodiode converts the received optical signal into an electrical signal, while the transimpedance amplifier (TIA) converts and amplifies the resulting photocurrent for further processing by the host-side circuitry. Together, they form the receiver section of the optical transceiver.

Q5. Is this module only suitable for 16G Fibre Channel?

No. Although it is primarily designed for Fibre Channel applications, the module supports multiple Fibre Channel rates, including 4.25G, 8.5G, and 14.025Gbps. Actual compatibility depends on the host equipment, optical system, and required protocol.

Q6. Can the DWDM channel be customized for a specific storage network?

Yes. For B2B projects, the DWDM channel can be selected according to the customer’s optical network design and ITU channel plan. EEPROM coding and other host compatibility parameters can also be customized for specific Fibre Channel switches or storage platforms.
