PCM-ZC-0187 is more than a conventional single-channel automotive Ethernet cable. Four independent high-speed data channels are consolidated into one 4-port GEMnet interface and carried together to a matching multi-port interface at the opposite end. Compared with routing four separate single-port cables, this 4-in-1 architecture reduces connector concentration and harness complexity around domain controllers, HPCs and central computing platforms while maintaining independent channel paths.

 

High-speed automotive links must withstand vibration, mechanical shock, thermal cycling and harness loading in addition to providing bandwidth. TE's 4-port GEMnet female housing incorporates CPA for positive mating assurance. Published GEMnet platform specifications include a connector disengagement force of ≥110N with the lock enabled, together with automotive vibration, mechanical shock and environmental validation.

Integrated 4 Channel GEMnet Architecture

Dual 4-port GEMnet interfaces consolidate four independent high-speed data channels into one harness while maintaining defined one-to-one channel mapping. Rather than duplicating a single Ethernet signal, the 4-in-1 architecture carries four separate links, reducing connector concentration, cable crossover and routing complexity around ECUs, HPCs and domain controllers.

Multi-Gigabit Multi-Protocol Platform

Built around the TE GEMnet high-speed platform for multi-gigabit Automotive Ethernet and SerDes connectivity, with platform capabilities up to 15GHz and 56Gbps. GEMnet supports technologies including 100/1000BASE-T1, 2.5/5/10/25GBASE-T1, GMSL2/3, FPD-Link IV, PCIe, MIPI, HDBaseT and ASA, providing scalability for next-generation vehicle data architectures.

High-Density Interface with CPA Locking

The multi-port GEMnet architecture increases high-speed connection density within limited controller interface space, making it suitable for HPCs, ADAS domain controllers and central computing platforms. The 2386629-series 4-port female housing features a 180° design with CPA mating assurance to improve mechanical retention against vehicle vibration, shock and harness movement.

OEM 4-Channel Customization & Integration

PCM-ZC-0187 can be configured with project-specific cable length, four-channel mapping, key code, cable construction, labeling and validation requirements. This allows each high-speed channel to correspond accurately with HPC, ECU, domain-controller or test-platform interfaces, providing greater flexibility for central computing, ADAS, smart cockpit and OEM vehicle-network integration.

HPC & Domain Controllers

 

Designed for multi-channel high-speed trunk links between automotive HPCs, ADAS domain controllers, central computers and zonal controllers. Four independent channels are consolidated through one GEMnet interface, reducing connector and cable concentration around high-performance ECUs.

Autonomous Driving & Sensor Data

 

Suitable for high-speed backbone connections between autonomous driving computers, radar, LiDAR and sensing control units, providing consolidated physical data paths for perception and sensor-fusion architectures.

Q1:With this high-density 4-in-1 layout running concurrent 100Mbps/1000Mbps data, will it introduce severe crosstalk across channels?

A1: Legacy parallel splitters suffer from massive induction crosstalk that collapses network data frames. We solve this by optimizing internal wire breakouts and PCB traces via micro-scale EM simulation layout, and nesting a "fully enclosed quad-chamber metal inner matrix" prior to overmolding. Armored under separate high-density aluminum foil wrap per pair, the Near-End Crosstalk (NEXT) suppression ratio is squeezed into deep lows, guaranteeing linear, independent full-duplex traffic across all channels.

Q2: In-vehicle routings span long spans; if this wire runs near ignition systems or high-power EV inverters, will data suffer from EMI noise?

A2: Absolutely not. Automotive high-speed Ethernet PHY layer EMC evaluation protocols are famously punishing. In addition to separate aluminum foil per pair (STP), this wire incorporates an overall comprehensive heavy-duty high-density copper braiding mesh shield, bonded 360-degree seamlessly to grounded metallic connector shells. This establishes a fortified electromagnetic defense net that traps and grounds out external high-frequency stray radiation, keeping the differential wave profile pristine.
