UGREEN 10Gbps RJ45 Female-to-Female Coupler (15117)
An exhaustive, practical guide to the exact connector path, verified performance, construction, setup, compatibility, safe use and troubleshooting.
Product overview
Overview
UGREEN 15117 is a passive inline coupler for joining two compatible male-ended Ethernet patch cables. It provides two female RJ45 sockets, shielded internal construction and an aluminium-alloy exterior. The listed ceiling is up to 10Gbps, but the joined channel remains limited by its lowest-category cable, weakest termination, slowest port and total length.
The buying decision begins with the exact interfaces and application, not the largest printed number. Confirm that the physical ports, protocol, device software and complete route match this model.

Port and direction check
Choose the right connection
2 × RJ45 female sockets for two male Ethernet patch-cable plugs
Ethernet data is bidirectional; either female socket may face either side of the link. The coupler has no source, destination, power or software side.
Inspect port labels and connector shapes under good light before routing. A physically similar socket may serve telephone, console, management, USB or power rather than the network job described here.
Speed, bandwidth and negotiation
Verified network performance
Listed ceiling: up to 10Gbps, backward compatible with 1000/100/10Mbps. The 100m/328ft figure is the maximum total channel formed by both cables and the coupler, not additional distance created by the coupler.
A maximum link rate is not the same as measured payload throughput. Protocol overhead, storage speed, CPU load, router processing, remote servers and internet service can all reduce the number shown by an application.
For a useful test, first confirm the negotiated link rate, then run a local transfer between capable devices before testing a public speed service.

A reliable first connection
Setup and usability guidance
Follow a controlled sequence so connector, network and software faults remain easy to isolate.
- Confirm both existing cables use intact male RJ45 plugs and are suitable for the intended speed.
- Add the lengths of both cables and keep the full Ethernet channel within the applicable 100m/328ft limit.
- Insert one cable into each female socket until both retaining clips click.
- Support the coupler so cable weight does not pull on either socket.
- Check link lights and negotiated speed at both endpoints.
- Run a local throughput or packet-stability test before securing the route.
- If performance falls, test each cable directly and replace the lower-category or damaged component.

Important exclusions
What this product does not do
These exclusions prevent the most common wrong-product purchases and unsafe installations.
- It does not amplify, repeat, regenerate, route or switch an Ethernet signal.
- It does not add 100m/328ft beyond the normal complete-channel limit.
- It does not improve a damaged cable, poor termination or slow network port.
- It does not create Wi-Fi, add an Ethernet port or convert fibre, USB or telephone wiring.
- It does not have a verified PoE class or wattage promise on this page.
- It does not have a published waterproof, outdoor, burial, in-wall or fire rating.
Best-practice checklist
What to do
Protect the connection and make later diagnosis straightforward.
- Use the same or better cable category on both sides where practical.
- Keep the joined total length within the applicable Ethernet channel limit.
- Seat both latches fully and support the coupler on a stable surface or tray.
- Test each individual cable directly before blaming the coupler.
- Keep the contacts clean, dry and protected from debris.
- Use one correct-length cable instead when a permanent uninterrupted run is practical.
A labelled, supported and tested connection is easier to maintain than one hidden immediately after purchase.
Avoid these mistakes
What not to do
Most failures come from wrong interfaces, unsupported claims, strain or uncontrolled channel changes.
- Do not describe the coupler as an active extender or signal booster.
- Do not count 328ft as extra length added to two already long cables.
- Do not daisy-chain several couplers without testing the complete channel.
- Do not let the coupler hang by the cables or become a trip point.
- Do not expose it to rain, standing water, burial or unapproved wall spaces.
- Do not promise PoE pass-through without verifying the exact power class and full installation path.
Stop using the product if a connector, housing, jacket or lead is cracked, loose, contaminated, unusually hot or exposes conductive parts.
Read before installation
Warnings and limitations
The following limits remain important even when the connector appears to fit.
- Every inline connection consumes channel margin and adds contact points.
- The 10Gbps ceiling requires suitable cables, sound terminations and 10G-capable network ports.
- The total-channel maximum is 100m/328ft, not 100m per cable.
- PoE is not claimed because it is not verified in the exact current body or artwork.
- No waterproof, outdoor, direct-burial, in-wall, plenum, LSZH or fire-resistance rating is stated.
- Replace the coupler if either socket becomes loose, contaminated, bent or unusually hot.

Problem-to-check sequence
Troubleshooting guide
| No link after joining | Reseat both plugs, test each cable directly, then test the coupler with two known-good short leads. |
|---|---|
| 10Gbps falls to a lower speed | Check both cable categories, port capabilities, total length and termination quality; the weakest part controls negotiation. |
| Link changes when touched | Support the coupler and inspect both latches and sockets for looseness or damage. |
| PoE device does not power | Remove the coupler and test a verified PoE-rated direct cable path; no PoE class is promised here. |
| High errors or packet loss | Shorten the channel, remove extra joins and replace any suspect cable or connector. |
Change one variable at a time. A known-good direct connection is the fastest way to separate a product fault from a port, cable, driver, address or network problem.

Product-specific FAQ
Open any question for a concise answer about exact SKU 15117.
What does UGREEN 15117 connect?
It joins two standard male-ended RJ45 Ethernet patch cables through two female RJ45 sockets.
Is the coupler directional?
No. Ethernet data is bidirectional and either socket can face either side of the link.
Does it boost or repeat the signal?
No. It is a passive joiner with no power or active electronics; it cannot regenerate a weak or damaged channel.
Can it add 328ft to my existing cables?
No. 328ft or 100m is the maximum total channel figure, including both cables, both endpoints and the inline coupler.
Can it support 10Gbps?
Up to 10Gbps is listed when both cables, their terminations, the network ports and total length provide adequate channel performance.
Which cable categories are listed?
Cat8, Cat7, Cat6A, Cat6, Cat5e and Cat5 are listed. The complete link performs at the level of its weakest component.
Will it increase a Cat5 cable to Cat7 or Cat8?
No. A coupler cannot change cable category, repair termination quality or upgrade network ports.
Does it need a driver or power supply?
No. It is passive and independent of the operating system.
Is PoE pass-through guaranteed?
No exact PoE class or pass-through rating is verified in the current body or artwork, so this page makes no PoE promise.
Can it be used outdoors or inside a wall?
No waterproof, outdoor, burial, in-wall, plenum, LSZH or fire rating is stated. Use installation-rated components where regulations require them.
Why did the link speed fall after adding it?
Test both cables directly, check total length, connector seating and port capability, and replace the lowest-category or damaged component.
What is included?
The package is treated as one UGREEN 15117 RJ45 female-to-female coupler. Ethernet cables are not listed as included.
Exact-model verification
Research and source note
The exact current product record and seven gallery images establish a passive female-to-female RJ45 coupler, up to 10Gbps, backward-compatible 10/100/1000Mbps operation, Cat8/Cat7/Cat6A/Cat6/Cat5e/Cat5 cable compatibility, gold-plated copper contacts, retaining clips and an aluminium-alloy outer shell. The 328ft statement is treated as the maximum total Ethernet channel length, not distance added by the coupler. PoE is omitted because it appears only in tags and is not verified by the exact body or artwork.
