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

For storage networking and DWDM deployments, our engineering team can support sample evaluation and compatibility testing with specific Fibre Channel switches, storage platforms, and optical transport equipment. Customized host identification and wavelength configurations can be prepared according to the customer’s network architecture and deployment

Q1. Why is C-band DWDM useful for Fibre Channel storage networks?

C-band DWDM allows multiple optical channels to be carried over the same fiber infrastructure using different wavelengths. This can increase the capacity of existing fiber routes and provide an efficient approach for extending storage network connectivity between locations without deploying additional fiber for every connection.

Q2. How should the DWDM wavelength be selected for this transceiver?

The wavelength should be selected according to the DWDM channel plan of the optical network. If the transceiver is connected through a DWDM MUX/DEMUX, its wavelength must correspond to the appropriate optical channel. The complete system should also be evaluated for insertion loss and available optical power budget.

Q3. Why does a 40km Fibre Channel module use a cooled EML laser?

A cooled EML laser provides improved wavelength stability and optical performance over changes in operating temperature. This is particularly valuable in DWDM systems, where precise wavelength control is required to maintain reliable operation within closely spaced optical channels.

Q4. What is the purpose of the integrated TIA in the receiver?

The transimpedance amplifier converts the current generated by the PIN photodiode into a usable electrical signal and provides amplification for subsequent signal processing. Integrating the TIA into the receiver architecture helps provide a practical and compact solution for high-speed optical signal reception.

Q5. Can this transceiver be used for Ethernet instead of Fibre Channel?

The module is primarily designed and specified for Fibre Channel applications at 4.25G, 8.5G, and 16G rates. Although some optical characteristics may resemble those of other 10G-class transceivers, protocol and host compatibility should be verified before using it in Ethernet equipment.

Q6. What should be evaluated before deploying a 40km DWDM Fibre Channel link?

The complete optical link should be evaluated rather than relying only on the nominal 40km distance. Important factors include fiber attenuation, MUX/DEMUX insertion loss, connector and splice losses, selected wavelength, optical power budget, and compatibility between the transceivers and Fibre Channel equipment.
