PACSystems RMX and CMX Fiber Cable part numbers

As of 3/26/2026, the current documentation is showing outdated part numbers and limited information on the fiber cables.

• GFK-2300G - Manual RMX128
• GFK-2511R - IPI RMX128
• GFK-2308Z – HSB Manual

 Here is the cross-reference to the current fiber optic cable part#s

1. VMICBL-000-F5-002 → IC695CBL010-FS-002 – Cable, simplex multimode fiber, 5 ft (1.52 m)
2. VMICBL-000-F5-003 → IC695CBL010-FS-003 – Cable, simplex multimode fiber, 10 ft (3.05 m)
3. VMICBL-000-F5-004 → IC695CBL010-FS-004 – Cable, simplex multimode fiber, 25 ft (7.62 m)
4. VMICBL-000-F6-001 → IC695CBL010-FD-001 – Cable, duplex multimode fiber, 6 ft (1.83 m)
5. VMICBL-000-F6-002 → IC695CBL010-FD-002 – Cable, duplex multimode fiber, 10 ft (3.05 m)
6. VMICBL-000-F6-003 → IC695CBL010-FD-003 – Cable, duplex multimode fiber, 16 ft (4.88 m)

Q1: Are the legacy VMICBL fiber cables still valid, and what are the current part numbers?

A1: Yes, functionally they are still valid. VMICBL-000-F5/F6 cables referenced in existing manuals have been replaced by IC695CBL010-FS/FD part numbers. There is no change in performance or application (GFK-2511R, Ordering Information).

Q2: Should simplex or duplex cables be used for an RMX128 redundancy link?
A2: Duplex multimode fiber cables are supported and intended for RMX128-to-RMX128 two-node redundancy links. Simplex cables are required only for reflective memory networks with more than two nodes (GFK-2300G, Section 3.4; GFK-2308Z, Section 4.1.3).

Q3: Why do RMX128 diagrams show crossed TX/RX connections?
A3: The diagrams illustrate required signal flow. RMX128 fiber ports are unidirectional, so TX on one module must connect to RX on the other and vice versa to form the two-node ring (GFK-2511R, Introduction; GFK-2308Z, Figure 5).

Q4: Are Emerson duplex cables already crossed, or do they need modification?
A4: Emerson duplex multimode cables intended for RMX applications are factory-polarized for proper TX/RX alignment and do not require any field modification (GFK-2300G, Section 3.1.3; GFK-2308Z, Figure 5).

Q5: Is using two simplex cables still acceptable?
A5: Yes. Two simplex cables will work and remain a safe option. However, for a direct RMX128-to-RMX128 redundancy link, a single Emerson duplex cable (IC695CBL010-FD-0xx) is correct out of the box (GFK-2300G, Section 3.4).
