Product Overview
The Allen-Bradley 1783-SFP100ZXC is a Stratix 100BASE-ZX singlemode fiber Small Form-factor Pluggable (SFP) transceiver. It provides a 100 Mbps optical Ethernet connection for compatible Stratix industrial switches, using a dual-LC fiber interface and a nominal optical wavelength of 1550 nm. Its specified link reach is up to 80 km over compatible singlemode fiber, making it suitable for network connections spanning large industrial sites or geographically separated facilities. <Cite refs={[“turn464232search0″,”turn464232search12”]}/>
In a large manufacturing plant, control networks may need to connect equipment rooms, remote production buildings, utility stations, or distributed process areas. Where the fiber route extends well beyond the reach of conventional copper Ethernet, the 1783-SFP100ZXC can provide an optical link between compatible Stratix switches. This allows Ethernet traffic from PLCs, HMIs, and other networked equipment to travel over a long-distance fiber connection.
The ZX optical interface is intended for long-reach singlemode links rather than short copper connections or ordinary multimode fiber runs. Its 1550 nm wavelength and specified optical characteristics must match the transceiver at the opposite end of the link. Fiber type, total path loss, connectors, splices, and intermediate patch panels all affect whether the link operates within the required optical budget.
The 1783-SFP100ZXC operates at Fast Ethernet speed, not Gigabit Ethernet. It is therefore appropriate when a compatible network requires 100 Mbps connectivity over a long singlemode fiber route, but it is not the right choice where the link must operate at 1000 Mbps. Network engineers should also check the switch’s SFP compatibility and the required optical interface before installing or replacing the module.

Working Principle
The 1783-SFP100ZXC converts electrical Ethernet data from the switch’s SFP interface into optical signals for transmission over singlemode fiber. At the receiving end, a compatible transceiver converts the optical signal back into electrical Ethernet data for the connected switch.
A typical link is arranged as follows:
Stratix Switch → 1783-SFP100ZXC → Dual-LC Singlemode Fiber → Compatible ZX Transceiver → Remote Stratix Switch
When a switch forwards an Ethernet frame toward a remote network, the transceiver encodes the data into an optical signal at its specified wavelength. The fiber carries that signal to the receiving transceiver, which recovers the data and passes it into the remote switch. The switches handle Ethernet forwarding; the SFP modules provide the physical optical connection.
The stated 80 km reach is a maximum specified link distance, not a guarantee that every 80 km fiber route will operate correctly. The complete optical path must meet the transmitter and receiver power requirements. Long routes with numerous splices, patch panels, or connectors require particular attention to insertion loss and connection quality.
Because the module uses a 1550 nm singlemode interface, both ends of the link must have compatible optical characteristics. A 100BASE-FX multimode module or a 100BASE-LX singlemode module should not be treated as an automatic substitute. Their wavelengths, optical budgets, and supported distances differ.
If a long-distance link fails to establish communication, check the fiber polarity, connector cleanliness, transceiver seating, remote-end module type, and total optical loss. Also verify the switch’s supported SFP configuration and port status.
Role in a Stratix Industrial Ethernet Network
The 1783-SFP100ZXC provides the long-distance optical connection between compatible Stratix network switches. It allows industrial Ethernet traffic to cross a singlemode fiber route while the switches manage network forwarding and segmentation.

Installation and Maintenance
- Verify the complete model reference: Confirm that the module is 1783-SFP100ZXC and that the network requires 100BASE-ZX singlemode connectivity.
- Check switch compatibility: Confirm that the intended Stratix switch supports this transceiver and its optical interface.
- Verify the remote transceiver: Ensure that the opposite end uses a compatible 100BASE-ZX optical module with matching wavelength and link characteristics.
- Confirm the fiber type: Check that the installed route uses compatible G.652 singlemode fiber.
- Assess the optical path: Calculate or measure the total loss introduced by fiber length, connectors, splices, and patch panels.
- Inspect the dual-LC connectors: Check for contamination, damaged ferrules, or loose connector housings before connecting the fiber.
- Follow laser-safety precautions: Never look directly into an optical port or fiber end. Follow the applicable procedures for optical equipment handling.
- Install the transceiver correctly: Insert the SFP module into the supported switch slot according to the equipment installation procedure.
- Check fiber polarity: Confirm that the transmit path at one end connects to the receive path at the opposite end.
- Verify link status: Check the switch-port indicators and management interface to confirm that the optical link has established communication.
- Investigate excessive optical loss: If the link is unstable, inspect connectors, splices, patch panels, fiber damage, and the optical power budget. Shorter-than-expected links may require attenuation assessment according to the transceiver specifications.
- Record the link configuration: Document the module references, switch ports, fiber route, measured optical loss where available, and commissioning results.

Technical FAQs
How does the 1783-SFP100ZXC differ from the 1783-SFP100EXC?
Both are 100 Mbps singlemode fiber SFP transceivers, but the 1783-SFP100ZXC uses a 1550 nm 100BASE-ZX interface with a specified reach of up to 80 km. The 1783-SFP100EXC uses a 1310 nm 100BASE-EX interface with a specified reach of up to 40 km. The two modules have different optical characteristics and should not be substituted without checking the complete link design.
Can this transceiver be connected directly to a copper Ethernet port?
No. The 1783-SFP100ZXC uses a dual-LC fiber interface. A compatible fiber connection or appropriately engineered network interface is required; an RJ45 copper cable cannot connect directly to its optical ports.
Why is the actual usable distance sometimes less than 80 km?
The maximum reach depends on the complete optical budget, including fiber attenuation, connector loss, splices, and patch panels. The remote receiver must receive a signal within its specified power range, so the installed route must be assessed rather than selected by distance alone.
Is the 1783-SFP100ZXC suitable for a Gigabit backbone?
No. It supports 100BASE-ZX at 100 Mbps. For a compatible Gigabit singlemode link, the 1783-SFP1GZX may be considered, subject to switch compatibility, the required optical budget, and the intended fiber distance.
