FiberMania provides OEM and customized manufacturing services for 10G SFP+ CWDM optical transceivers. Customers can specify the required CWDM wavelength according to their network channel plan, as well as requirements for EEPROM coding, equipment compatibility, product labeling, housing identification, packaging, and other project-specific configurations.

For CWDM deployments, we can support wavelength-specific configurations for different MUX/DEMUX channel plans. Compatibility samples can also be provided for evaluation with customer switches, routers, transport equipment, and other optical networking platforms before volume production.

Q1. How should the wavelength be selected for a CWDM network?

The wavelength should be selected according to the available CWDM channel plan and the corresponding MUX/DEMUX ports. For example, if a network uses a specific CWDM channel, the transceiver at each end of the link should use the appropriate wavelength for that channel. Wavelength selection should therefore be determined during the overall CWDM system design rather than independently selecting a module.

Q2. Can this transceiver really transmit up to 100km?

The module is designed for links of up to 100km under appropriate optical conditions. Actual achievable distance depends on the total link loss, fiber attenuation at the selected wavelength, connector and splice losses, MUX/DEMUX insertion loss, and the available optical power budget. A complete link-budget calculation is recommended for 100km deployments.

Q3. Why does this module use an EML laser and APD receiver?

EML lasers are well suited to high-speed long-distance optical transmission, while APD receivers provide high optical sensitivity. Combining these components helps the transceiver support the longer optical reach required for 10G CWDM links.

Q4. Can different CWDM wavelengths be used on the two ends of a point-to-point link?

For a conventional point-to-point CWDM link, the transceivers at the two ends normally need to be configured according to the intended optical channel and system architecture. When MUX/DEMUX equipment is used, different wavelength channels can be assigned to different links, but each optical path must follow the corresponding CWDM channel plan.

Q5. What equipment can this 10G CWDM SFP+ module be installed in?

It can be used in compatible networking and optical transport equipment with SFP+ ports, including switches, routers, transport platforms, and other 10G systems. Host compatibility should be verified because some equipment platforms require specific EEPROM coding or approved transceiver configurations.
