Product Introduction
The GE ACC-5595-208 is a managed Reflective Memory hub designed for GE/Abaco 5565-series real-time networks. Rather than routing conventional IP packets, it distributes shared-memory data across an optical network so connected computing nodes can exchange synchronized data with very low communication overhead.
This hardware is particularly relevant in real-time simulation, test systems, industrial control simulation, and other systems where deterministic data distribution is more important than conventional Ethernet networking. The hub regenerates the serial optical signal at each port, helping limit optical-link loss and accumulated jitter across the network.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
A common procurement error is treating the ACC-5595-208 as a standard fiber Ethernet switch. It is a Reflective Memory hub, and replacing it with an ordinary managed Ethernet switch changes the network architecture completely.
Typical Applications
- Reflective Memory networks — Central optical interconnection for 5565-series Reflective Memory nodes.
- Real-time simulation — Aircraft, engine, vehicle, plant, and hardware-in-the-loop simulation environments.
- High-speed test systems — Shared data distribution between multiple real-time computing nodes.
- Industrial control simulation — Applications requiring synchronized data exchange between independent processing systems.
Technical Pitfalls to Avoid
- Do not confuse 2 Gb/s Reflective Memory with 2 Gb Ethernet. The nominal data rate is similar, but the protocol and network behavior are fundamentally different.
- Check the optical configuration.
ACC-5595-208is associated with eight multimode SFP positions. The relatedACC-5595-280configuration is identified with eight single-mode ports, so the two should not be treated as interchangeable without checking the installed optical links. - Verify the SFPs separately. The hub uses pluggable optical transceivers. A replacement chassis without the correct optical modules may not restore the original network.
- Check the network topology before replacement. The hub can be cascaded and the overall Reflective Memory network can reach up to 256 nodes. Replacing one hub without documenting upstream/downstream optical connections can create difficult-to-diagnose network faults.
- Do not assume the Ethernet port carries Reflective Memory traffic. The 10Base-T Ethernet interface is provided for remote access/control; it is not the primary high-speed memory-network interface.

Procurement Note
For an , verify four items before approving a replacement:
complete part number → 8-port configuration → multimode SFP type → existing 5565 network topology.
There is substantial listing noise around this part number, including descriptions calling it a generic fiber switch, relay module, or PLC communication device. The technically supported identification is GE/Abaco 5595-series 2 Gb/s Reflective Memory Hub Assembly with eight multimode optical ports.
⚠️ Legacy model: replacement evaluation should include the installed SFP transceivers, firmware revision, optical connector type, and the actual 5565 Reflective Memory node configuration.
