Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the AFCT-57D3ATMZ is determined by alignment of the following critical parameters:

• Data Rate: The substitute must support the required transmission speed (2.125GBd, 4.25GBd, or 8.5GBd)
• Wavelength: Must operate at 1310nm to ensure compatibility with existing fiber infrastructure
• Voltage Supply: Must operate at 3.3V to match host system requirements
• Connector Type: Must use LC connectivity for physical and optical alignment
• Mounting Type: Must be SFP+ pluggable format for slot compatibility
• Form Factor: Must be SFP+ standard to ensure mechanical fit in existing equipment

The AFCT-57D3ATMZ-C qualifies as a substitute based on matching wavelength (1310nm), voltage supply (3.3V), connector type (LC), and SFP+ pluggable mounting. The substitute supports 10Gbps operation, which encompasses the data rates of the original part.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-57D3ATMZ-C is available as an active product from ATGBICS, providing a viable path forward for systems currently using the obsolete AFCT-57D3ATMZ. Both modules share critical electrical and mechanical compatibility parameters: identical wavelength (1310nm), supply voltage (3.3V), and SFP+ form factor. The substitute operates at 10Gbps, which supports all data rates specified for the original Broadcom module. Selection of the AFCT-57D3ATMZ-C eliminates obsolescence risk while maintaining system compatibility with existing optical infrastructure and host equipment.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57D3ATMZ-C be used as a direct replacement for the AFCT-57D3ATMZ?

A: Yes, the AFCT-57D3ATMZ-C meets the core compatibility requirements: identical wavelength (1310nm), supply voltage (3.3V), LC connector type, and SFP+ pluggable form factor. Both modules are designed for general-purpose optical communication applications.

Q: What is the significance of the data rate difference between the two modules?

A: The original AFCT-57D3ATMZ supports 2.125GBd, 4.25GBd, and 8.5GBd operation. The AFCT-57D3ATMZ-C operates at 10Gbps, which encompasses all specified data rates of the original part. This higher capability ensures compatibility across all intended applications.

Q: Are there packaging differences between these modules?

A: The AFCT-57D3ATMZ is supplied in standard packaging, while the AFCT-57D3ATMZ-C is supplied in tray packaging. Both maintain identical SFP+ form factor and mechanical dimensions for equipment slot compatibility.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation. The AFCT-57D3ATMZ-C, maintained as an active product by ATGBICS, provides continued availability and support for equivalent functionality.

Q: Are there compliance considerations when substituting these modules?

A: The AFCT-57D3ATMZ is ROHS3 compliant. Compliance status for the AFCT-57D3ATMZ-C should be verified with the supplier to ensure alignment with system-level regulatory requirements.
