Honeywell 51202971-312 Fiber Optic Interface Cable

Configured for high-speed data transmission and communication interconnection within Experion LX control system networks, the Honeywell 51202971-312 (51202329-312 or 51202971-312 Fiber Optic Interface Cable) provides direct physical signal execution across distributed nodes.

Hardware Specifications

Process Control and Signal Communication Interfaces

The assembly integrates within Honeywell Experion LX process automation architecture, maintaining strict channel isolation and cold junction compensation (CJC) path integrity across distributed nodes. Standard configuration supports high-speed Fiber Optic Ethernet (FOE) communication layers operating at an 850 nm wavelength with a 1 Gbps data rate capability. The multi-mode fiber construction and optical transmission design eliminate electromagnetic interference (EMI) across noisy industrial floors, ensuring deterministic bus operation and low-latency packet transmission between system components.

Frequently Asked Questions

Q: Does the 51202971-312 support hot-swapping on active controller networks?

A: Fiber optic connections should be handled with associated interface modules powered down to prevent potential optical port damage from stray laser or light emissions.

Q: What is the maximum attenuation and bandwidth specification for this fiber optic cable?

A: The OM3 50/125 micron multi-mode fiber features an attenuation of less than or equal to 3.5 dB/km at 850 nm and a bandwidth of 2000 MHz-km at 850 nm.

Field Installation Guidelines

1. Ensure fiber optic connector end-faces are kept clean and free of dust or oils using approved optical cleaning tools prior to insertion into transceiver ports.
2. Maintain the minimum bend radius specified for the OM3 fiber core to prevent signal attenuation or permanent glass core damage during cabinet routing.
3. Secure LC duplex connectors firmly into terminal interfaces, ensuring locking latches are fully engaged to withstand industrial vibration environments.
