AFCT-79EEPZ Equivalent & Substitute Parts

Part Overview

The AFCT-79EEPZ is a 40G QSFP+ LR transceiver module manufactured by Broadcom Limited, designed for 10 Gbps networking applications over single-mode fiber (SMF) with a 10 km transmission distance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, upgrades, and procurement planning. Substitute parts must maintain compatibility with existing QSFP+ infrastructure while meeting the electrical and mechanical specifications required for long-reach optical networking.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFCT-79EEPZ is determined by the following critical parameters:

• Form Factor & Connector: QSFP+ pluggable module with LC connector interface
• Data Rate Compatibility: 40 Gbps operation supporting long-reach (LR4) transmission
• Wavelength: 1310 nm for single-mode fiber applications
• Transmission Distance: 10 km capability over SMF
• Voltage Supply: 3.3V operation
• Regulatory Compliance: REACH Unaffected status and RoHS compliance

The substitute part AFCT-79EEPZ-C, manufactured by ATGBICS, meets these core parameters and is classified as active product status, providing a direct functional replacement for the obsolete Broadcom module.

Engineering Selection Recommendations

The AFCT-79EEPZ-C is the designated manufacturer-recommended substitute for the obsolete AFCT-79EEPZ. Selection of this alternative is supported by:

• Active Product Status: The substitute maintains current manufacturing and support status, ensuring long-term availability and supply chain reliability
• Regulatory Compliance: Both parts maintain REACH Unaffected status; the substitute adds RoHS Compliance certification
• Form Factor Compatibility: QSFP+ pluggable module design ensures mechanical and electrical compatibility with existing QSFP+ port infrastructure
• Functional Equivalence: The substitute supports the required 1310 nm wavelength, LC connector interface, and 10 km transmission distance over single-mode fiber
• Supply Availability: The substitute part maintains significantly higher inventory levels (10,304 pcs vs. 993 pcs), reducing procurement lead times

Frequently Asked Questions (FAQ)

Q: Can the AFCT-79EEPZ-C be used as a direct replacement in systems currently using the AFCT-79EEPZ?

A: Yes. Both modules are QSFP+ pluggable transceivers with LC connectors operating at 1310 nm wavelength over 10 km single-mode fiber links. The substitute maintains electrical and mechanical compatibility with existing QSFP+ port infrastructure.

Q: What is the significance of the data rate difference (10 Gbps vs. 40 Gbps)?

A: The AFCT-79EEPZ-C supports 40 Gbps operation, which is backward compatible with 10 Gbps systems. The module will operate at the speed negotiated by the host equipment, ensuring compatibility with legacy 10 Gbps infrastructure.

Q: Are there packaging considerations when ordering the AFCT-79EEPZ-C?

A: The substitute is supplied in Tray packaging. Verify that your procurement and storage procedures accommodate tray packaging formats, or confirm availability in alternative packaging configurations if required.

Q: Why is the original AFCT-79EEPZ classified as obsolete?

A: Obsolete status indicates that the manufacturer (Broadcom Limited) has discontinued production and support. The AFCT-79EEPZ-C provides an active, supported alternative with equivalent functionality.

Q: Do both parts meet the same regulatory requirements?

A: Both parts maintain REACH Unaffected status. The substitute additionally carries RoHS Compliance certification, meeting current environmental and hazardous substance restrictions.
