Hardware Specifications

Industrial Ethernet Optical Link Characteristics

The 490NOR00003 functions as a passive optical transmission medium and therefore introduces no protocol processing or firmware dependency. When deployed within industrial Ethernet architectures, network performance is primarily determined by the connected switches, transceivers, and controller communication modules.

The glass-fiber construction supports electromagnetic immunity characteristics inherent to fiber-optic media, eliminating conductive signal paths between interconnected equipment. MT/RJ terminations provide fixed optical connectivity for compatible ConneXium network components and automation platforms.

Frequently Asked Questions

Q: Does the 490NOR00003 require an external power supply? A: No. The cable is a passive fiber-optic assembly and consumes no electrical power.

Q: Is firmware compatibility relevant for this product? A: No. The cable contains no programmable electronics. Communication compatibility depends on the optical interfaces of the connected devices.

Q: Can the cable provide electrical isolation between network devices? A: Yes. Fiber-optic media does not create a conductive electrical path between endpoints, helping prevent ground-potential transfer through the communication link.

Field Installation Guidelines

• Verify that both connected devices support MT/RJ optical interfaces before installation.
• Maintain the manufacturer's minimum bend radius requirements to avoid optical attenuation increases.
• Keep fiber end faces clean and protected from dust contamination during installation.
• Route fiber cables separately from power conductors to prevent mechanical damage during maintenance activities.
• Avoid excessive pulling force during cable installation and secure the cable using appropriate strain-relief methods.
• Inspect connector locking mechanisms after installation to confirm proper seating within transceivers, switches, or communication modules.
• Use protective caps on disconnected fiber connectors to prevent contamination of optical surfaces.
