Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-725SMZ is determined by the following critical parameters:

Primary Compatibility Criteria:

• Data Rate: 25Gbps nominal operation
• Wavelength: 1310nm
• Mounting Type: Pluggable SFP28 form factor
• Connector Type: LC interface
• Applications: General Purpose 25 Gigabit Ethernet

Secondary Compliance Criteria:

• RoHS3 Compliance
• ECCN Classification: 5A991B5A
• Supply Voltage: Compatible operating range

The FTLF1436W5BCL from Finisar Corporation meets these substitution criteria. While the data rate specification is 25.78Gbps and the supply voltage range is 3.15V to 3.46V, these parameters remain within the operational envelope for general-purpose 25GE applications. Both modules share identical wavelength, connector type, mounting type, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can FTLF1436W5BCL directly replace AFCT-725SMZ in existing installations?

A: Yes. Both modules operate at 1310nm wavelength, support 25Gbps data rates, utilize LC connectors, and employ the SFP28 pluggable form factor. The FTLF1436W5BCL supply voltage range (3.15V to 3.46V) is compatible with the AFCT-725SMZ 3.3V specification.

Q: What is the difference between LC and LC Duplex connectors in this context?

A: Both connector types are compatible with SFP28 modules. LC Duplex provides dual-fiber connectivity in a compact form factor. The functional compatibility for 25GE general-purpose applications remains equivalent.

Q: Why is the AFCT-725SMZ listed as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer is discontinuing production. Current inventory (940 pieces) represents the final available stock. The FTLF1436W5BCL, with Active product status, provides continuity for ongoing and future applications.

Q: Are there compliance differences between these modules?

A: No. Both modules are ROHS3 compliant and share identical ECCN classification (5A991B5A), ensuring equivalent regulatory and export compliance.

Q: What is the significance of the 25.78Gbps specification on the FTLF1436W5BCL?

A: The FTLF1436W5BCL is specified for CPRI/ECPRI applications at 24.33Gbps nominal rate, with a maximum data rate of 25.78Gbps. This specification encompasses the 25Gbps general-purpose requirement of the AFCT-725SMZ, ensuring operational compatibility.

Q: How do packaging differences affect substitution?

A: The AFCT-725SMZ is supplied in Bulk packaging, while the FTLF1436W5BCL is supplied in Tray packaging. Both packaging formats are standard for SFP28 transceiver modules and do not affect functional compatibility or system integration.
