AVAGO AFCT-5715APZ Replacement for Multimode SFP Series

Product Overview

AVAGO AFCT-5715APZ Replacement for Multimode SFP Series: Smooth Migration from Legacy Fiber Links

The AVAGO AFCT-5715APZ is a 1.25 Gbps multimode SFP (Small Form-factor Pluggable) fiber transceiver operating at 850 nm with an LC duplex interface. As legacy fiber infrastructure ages and original AVAGO SFP modules approach end-of-life or become increasingly difficult to source, facilities engineers and network administrators face mounting pressure to identify a reliable, drop-in replacement that preserves link integrity without requiring wholesale infrastructure overhaul.

TOPNLMS supplies the AFCT-5715APZ as a direct replacement and upgrade solution for industrial Ethernet backbones, managed switches, media converters, and PLC communication networks where 1000BASE-SX or Fast Ethernet multimode fiber links are deployed. Whether you are maintaining a legacy SCADA backbone, upgrading a distributed I/O network, or replacing failed transceivers in a control cabinet fiber patch panel, this module is engineered to restore connectivity with zero re-cabling and minimal commissioning time.

Seamless Upgrade Solutions

A successful fiber link migration rarely involves a single component. When replacing the AFCT-5715APZ in an industrial control environment, the surrounding system architecture must be evaluated holistically to ensure the upgrade delivers long-term stability.

In managed switch applications — such as those using Cisco SG series, Hirschmann MACH or SPIDER switches, or Moxa EDS managed Ethernet switches — the AFCT-5715APZ slots directly into any SFP-compliant cage without firmware changes. For installations where the host switch uses a proprietary SFP lock (common in some Cisco Catalyst or Allied Telesis platforms), a compatible third-party unlock or an alternative SFP cage adapter may be required, though the AFCT-5715APZ is designed to negotiate standard 1000BASE-SX auto-negotiation without issue.

In PLC-integrated fiber networks — for example, systems built around Siemens SCALANCE X switches, Siemens CP 343-1 or CP 443-1 communication processors, or Allen-Bradley Stratix 5700 managed switches — the AFCT-5715APZ provides a direct path to restore fiber uplinks without modifying the PROFINET, EtherNet/IP, or Modbus TCP communication stack. The transceiver operates transparently at the physical layer, meaning the PLC program, I/O mapping, and network topology remain unchanged after replacement.

For distributed control system (DCS) fiber backbones — including those using Honeywell Experion or Emerson DeltaV fiber ring topologies — the AFCT-5715APZ can replace aging multimode SFPs in fiber media converters and ring switches without disrupting the redundant fiber path. Paired with an LC-LC multimode patch cord (OM2 or OM3), the replacement can typically be completed during a planned maintenance window of under 30 minutes per node.

When the migration scope extends beyond a single transceiver, TOPNLMS can also supply complementary components commonly required in the same upgrade cycle: LC duplex multimode patch cords, SFP slot dust caps for unused ports, fiber patch panel modules for control cabinet organization, and SFP-to-RJ45 copper transceivers for hybrid fiber-copper segments. For systems requiring signal isolation between fiber segments and copper I/O loops, fiber-to-copper media converters with built-in signal isolation are available as part of the same procurement.

In control cabinet environments where space is constrained, the SFP form factor of the AFCT-5715APZ offers a significant advantage over older GBIC or SC-interface transceivers. The compact SFP cage occupies minimal DIN rail or rack space, and the hot-swap capability means the module can be replaced without powering down the host switch or controller — a critical consideration in 24/7 process control environments where unplanned downtime carries direct production cost.

Retrofit Guidance FAQ

Q: Can I replace my existing multimode SFP with the AFCT-5715APZ without re-cabling?
A: Yes. The AFCT-5715APZ uses a standard LC duplex interface and is fully MSA-compliant. As long as your existing fiber patch cord is LC duplex multimode (OM1, OM2, or OM3), no re-cabling is required. Simply remove the old SFP, insert the AFCT-5715APZ, and the link will re-establish automatically.

Q: Is the AFCT-5715APZ compatible with my PLC’s managed switch SFP slot?
A: The AFCT-5715APZ is compatible with any SFP MSA-compliant cage operating at 1.25 Gbps / 850 nm multimode. This includes SFP slots on Siemens SCALANCE, Moxa EDS, Hirschmann, Cisco, and most industrial Ethernet switches. If your switch enforces vendor-specific SFP authentication (e.g., certain Cisco IOS versions), consult your switch documentation or contact TOPNLMS for compatibility confirmation.

Q: Will replacing the SFP affect my PROFINET, EtherNet/IP, or Modbus TCP communication?
A: No. The AFCT-5715APZ operates at the physical (PHY) layer only. It does not interact with the data link, network, or application layers. Your PLC program, I/O configuration, IP addressing, and communication protocol settings remain completely unchanged after the transceiver swap.

Q: What is the maximum fiber run distance supported?
A: On OM1 (62.5/125 µm) fiber, the AFCT-5715APZ supports up to 220 m. On OM2 or OM3 (50/125 µm) fiber, the reach extends to 550 m. For longer distances or single-mode fiber runs, a different SFP variant (e.g., 1310 nm single-mode) would be required.

Q: Can this module be installed while the switch is powered on?
A: Yes. The SFP form factor supports hot-swap insertion and removal. The host switch will detect the new transceiver and re-establish the fiber link without requiring a system reboot — minimizing disruption in live control environments.

Q: How do I verify the transceiver is functioning correctly after installation?
A: The AFCT-5715APZ supports Digital Diagnostic Monitoring (DDM / DOM) per SFF-8472. You can read real-time optical power (TX/RX), temperature, voltage, and bias current via your switch’s management interface. A stable RX power reading within the receiver sensitivity range confirms a healthy link.

Q: What if my legacy SFP used a different connector type (e.g., SC or MT-RJ)?
A: The AFCT-5715APZ uses LC duplex connectors. If your existing fiber infrastructure uses SC or MT-RJ connectors, you will need an LC-to-SC or LC-to-MT-RJ adapter or a new patch cord. TOPNLMS can advise on the appropriate adapter for your specific installation.

Warranty Assurance

Every AVAGO AFCT-5715APZ unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Before dispatch, each transceiver undergoes functional verification including optical power output measurement, receiver sensitivity check, and DDM register validation to confirm the module meets AVAGO’s original performance specifications.

If a unit exhibits any defect in materials or workmanship within the warranty period, TOPNLMS will arrange a replacement shipment at no additional cost. Our after-sales response target is within 24 business hours of a warranty claim submission.
