3A98763G02
3A98763G02 is original Westinghouse WDPF DCS dedicated single-core duplex industrial fiber optic patch cord, pre-configured for interconnection between DPU processing unit and WEStation operator station inside control cabinet, matching 3A98764G series yellow optical cable for whole-site field optical networking layout.
The cable adopts compact clip-on fixed design with orange outer sheath for quick visual classification, specially used for Westnet field bus optical signal transmission of WDPF distributed control system. Original Emerson-Westinghouse stopped new production permanently; available stock mainly consists of factory-tested refurbished cables and authentic dismantled original spare parts for overhaul replacement of thermal power, chemical and cogeneration DCS control cabinet.

1. Product Overview
3A98763G02 is original Westinghouse WDPF DCS dedicated single-core duplex industrial fiber optic patch cord, pre-configured for interconnection between DPU processing unit and WEStation operator station inside control cabinet, matching 3A98764G series yellow optical cable for whole-site field optical networking layout.The cable adopts compact clip-on fixed design with orange outer sheath for quick visual classification, specially used for Westnet field bus optical signal transmission of WDPF distributed control system. Original Emerson-Westinghouse stopped new production permanently; available stock mainly consists of factory-tested refurbished cables and authentic dismantled original spare parts for overhaul replacement of thermal power, chemical and cogeneration DCS control cabinet.
2. Technical Specifications
2.1 Optical & Electrical Performance
It uses industrial-grade multimode optical fiber core, standard 62.5/125μm core/cladding parameter, operating transmission wavelength 850nm, maximum effective transmission distance up to 2km under cabinet indoor layout.Working signal level conforms to WDPF Westnet bus optical protocol, no extra power supply required for optical path transmission; built-in anti-surge optical module protection structure to avoid instantaneous voltage spike damage caused by cabinet power fluctuation. Insertion loss ≤0.8dB per connector end, return loss ≥25dB to guarantee stable long-distance bus data communication.
2.2 Mechanical & Environmental Parameters
Fiber inner core wrapped with aramid fiber tensile layer, outer jacket is orange oil-proof flame retardant modified PVC with anti-ultraviolet and anti-aging property. Fixed factory standard length matches built-in cabinet wiring layout without on-site cutting.Continuous operating ambient temperature inside cabinet ranges from 0℃ to +55℃; spare storage temperature from -40℃ to +85℃, applicable working humidity 5%~95%RH non-condensing. Pass UL flame retardant and CE industrial optical communication certification standard.
2.3 Structural Advantages
Both ends fitted with factory pre-terminated ST-type molded optical connectors, integrated sealing design effectively prevent cabinet dust, moisture and corrosive gas from invading fiber end face to reduce signal attenuation. Built-in aramid fiber tension bearing layer greatly improves tensile and anti-bending performance to prevent fiber fracture from cabinet equipment long-term vibration; exclusive orange sheath distinguishes from yellow field optical cable (3A98764G series) for convenient maintenance line inspection and error-proof wiring.
3. Core Application & Supply
Realize optical isolation data transmission between cabinet DPU controller and operator workstation via Westnet bus, isolate strong electromagnetic interference from power cabinet to avoid DCS system communication crash. Widely applied in coal-fired power plant, petrochemical plant and central heating unit WDPF system routine maintenance replacement. Standard delivery cycle 2~4 weeks, rush order available, global shipment via DHL/UPS/Fedex international courier with
