3A98763G03
3A98763G03 is original Westinghouse WDPF DCS duplex multimode fiber jumper with fixed factory length, belonging to 3A98763G serial fiber family, orange outer sheath with buckle fixed structure, specially designed for Westnet fieldbus optical communication between DPU controller and WEStation operator workstation inside control cabinet. It matches 3A98764G series yellow field optical cable to complete the whole plant DCS optical networking layout. Original Emerson-Westinghouse has permanently suspended new production; existing supply mainly includes factory inspected refurbished cables and authentic dismantled original spare parts, widely used for overhaul replacement of thermal power, cogeneration and petrochemical WDPF distributed control system cabinet wiring.
Description
1. Product Overview
3A98763G03 is original Westinghouse WDPF DCS duplex multimode fiber jumper with fixed factory length, belonging to 3A98763G serial fiber family, orange outer sheath with buckle fixed structure, specially designed for Westnet fieldbus optical communication between DPU controller and WEStation operator workstation inside control cabinet.

Original Emerson-Westinghouse has permanently suspended new production; existing supply mainly includes factory inspected refurbished cables and authentic dismantled original spare parts, widely used for overhaul replacement of thermal power, cogeneration and petrochemical WDPF distributed control system cabinet wiring.
2. Technical Specifications
2.1 Optical Performance Parameters
Adopts industrial standard 62.5/125μm multimode fiber core, working transmission wavelength at 850nm, maximum indoor cabinet transmission distance reaches 2km, fully compatible with WDPF Westnet bus dedicated optical communication protocol. The optical path works in passive mode without external power supply; built-in anti-surge protection design to avoid fiber module damage caused by instantaneous voltage surge from cabinet power fluctuation. Single end connector insertion loss ≤0.8dB, return loss ≥25dB, ensuring stable long-term continuous data transmission of system bus.
2.2 Mechanical & Environmental Specifications
Inner fiber core wrapped with high-strength aramid fiber tensile reinforcement layer, outer jacket is orange modified flame-retardant anti-aging PVC with oil-proof and UV resistant performance, finished with OEM fixed length to fit standard cabinet wiring layout without field cutting. Continuous working ambient temperature inside closed cabinet ranges from 0℃ to +55℃; spare part storage temperature spans -40℃ to +85℃, applicable working humidity 5%~95%RH under non-condensing environment. The cable complies with UL flame retardant standard and CE industrial EMC certification requirement.
2.3 Structural Features
Both ends pre-terminated with ST type integrated overmolded optical connectors, sealed construction effectively prevents cabinet dust, moisture and corrosive gas from eroding fiber end face and leading to increased signal attenuation. Internal aramid tension structure greatly improves tensile and anti-bending capacity to prevent fiber breakage induced by long-term cabinet mechanical vibration. Distinct orange jacket differs from yellow field optical cable of 3A98764G series, facilitating on-site maintenance routing inspection and anti-misconnection construction.
3. Application & Supply Information
Core function is realizing galvanic isolation data transmission between DPU processing unit and operator station via Westnet optical bus, blocking strong electromagnetic interference from high-power cabinet power equipment to avoid DCS system communication interruption or offline fault. Mainly used for routine maintenance replacement of coal-fired power, chemical and central heating unit WDPF control system. Standard delivery lead time is 2~4 weeks, expedited order is acceptable; global delivery supported by DHL, UPS and FedEx international courier with formal product warranty.
