TE GEMnet quad port female connector, part number 2386629-1, black housing, factory built as a female to female extension on GG251 10G shielded automotive Ethernet cable, also built on LEONI Dacar 686-3. The quad port carries four independent 10G Ethernet channels. One end has a red service latch and the other end has a purple service latch. Available in 7 lengths from 0.5 m to 5 m. Built for zonal architectures that need to extend a GEMnet quad port link between two male pigtails.

TE GEMnet is a quad port automotive Ethernet connector system that carries four independent 10G channels in one housing. When a factory GEMnet quad port male pigtail is too short, or when bridging two male pigtails across a gap, a female to female extension cable is required.This cable covers that exact case. Both ends are the GEMnet quad port female, part number 2386629-1, black housing. The cable is GG251 10G shielded automotive Ethernet, also built on LEONI Dacar 686-3, rated for 10G per channel.

Whether you are extending a GEMnet quad port male pigtail or bridging two male pigtails in a zonal ECU, this female to female extension reaches the gap without cutting either factory harness. Pick the length that matches your routing.

TE GEMnet Quad Port Female to Female

This female to female extension cable joins two TE GEMnet quad port female connectors, part number 2386629-1, on GG251 10G shielded automotive Ethernet cable also built on LEONI Dacar 686-3. Fewer connectors and fewer cables mean less weight, less space used in the door sill or roof rail, and faster assembly on the production line.

The two colored latches are a visual aid during installation. They help the technician identify which end faces the zonal ECU and which end faces the device side, so the cable is routed the same way every time. The connector interface itself is the same GEMnet quad port female on both ends, and either end mates to a standard GEMnet quad port male plug.

TE GEMnet Quad Port Female to Female

Inside the quad port housing, each of the four contacts is individually shielded and grounded through a 360 degree shield termination. The GG251 cable behind each contact is a fully shielded twisted pair rated for 10GBASE T1 operation, built to hold 100 ohm differential impedance across the full cable length.

Available in 7 lengths from 0.5 m to 5 m. The 0.5 m and 1 m options fit tight ECU jumps inside the dashboard. The 1.5 m and 2 m options cover door to pillar routing. The 3 m to 5 m options reach from the trunk ECU to roof mounted sensors or across the cabin. Every assembly is per channel continuity and shielding tested before dispatch, so all four channels are verified working before the cable ships.

Applications

Application	How It Is Used	What It Enables
Male to male bridge	Bridge two GEMnet quad port male pigtails.	Reaches across the gap between two male pigtails.
Bench test rig	Wire GEMnet quad port ECUs to test instruments.	Repeatable 10G test links between two male pigtails.
Quad port extension	Extend a factory GEMnet quad port male pigtail.	Reaches a relocated zonal ECU without cutting the factory harness.

Closing line: because both ends are factory terminated GEMnet quad port females on the same shielded GG251 cable, all four 10G channels stay impedance matched end to end.

Product FAQ

Q1: Is this a genuine TE GEMnet connector?

Yes. The GEMnet quad port female is genuine TE Connectivity, part number 2386629-1, black housing. The cable is GG251 10G shielded automotive Ethernet, also built on LEONI Dacar 686-3.

Q2: What is the difference between the red and purple latches?

The red and purple latches are service aids on the two female ends. They help identify which end goes where during installation. The connector interface is the same GEMnet quad port female on both ends.

Q3: Which length should I order?

0.5 m to 1 m for tight ECU jumps, 2 m to 3 m for dashboard routing, 4 m to 5 m for trunk or across cabin runs. When in doubt, take the next length up.

Q4: Can you make custom lengths?

Yes. We support custom lengths from 0.5 m to 5 m and beyond. Send us your target length and routing requirement, and we will quote the matching cable.
