Description

Specifications of RJ45 Inline Coupler

Feature Details
Overview A plug-and-play RJ45 inline coupler that joins two Ethernet cables end-to-end. Designed for Cat6/Cat5e networks, it lets you quickly extend cable runs without any tools. Ideal for CCTV/IP camera links, router/switch connections, patch panel hookups, home offices, or gaming LANs.
Connectivity This RJ45 inline coupler has 2 × RJ45 (8P8C) female ports (straight-through wiring), enabling two pre-terminated cables to plug in and link seamlessly.
Network Support Rated for Cat6 (250 MHz, 10/100/1000 Mbps). Supports Gigabit Ethernet at full Cat6 speeds and is fully backward compatible with Cat5e installations.
Material & Build Durable housing (shielded stainless steel or robust ABS plastic). Gold-plated contact pins ensure corrosion-resistant, stable connections. Metal shielding reduces interference for reliable signal integrity.
Installation Tool-free, plug-and-play design – simply insert RJ45 plugs on each side. No crimping or special tools are required, making it perfect for quick network extensions or repairs.
Dimensions Compact inline size: approx. 31 × 16 × 16 mm (L×W×H), so it easily fits behind devices or in cable ducts.
Applications This RJ45 inline coupler is ideal for CCTV/IP cameras, PoE devices (security cameras, VoIP phones), routers/switches, patch panels and general home/office networks. Great for extending or repairing cables in offices, homes or events (gaming LANs, etc.).
Standards Meets ANSI/TIA-568 wiring standards (Cat6 compliant) and is compatible with IEEE 802.3 PoE. RoHS compliant (lead-free).

    Definitely a good website to buy your RJ45 coupler. Worth buying it from Securicam if you need one

  2. vorbelutr ioperbir –

    Spot on with this product; I truly assume this website wants far more consideration. I’ll most likely be back to buy more; thanks for the product.

FAQs

What is an RJ45 inline coupler?
It’s a small female-to-female RJ45 (8P8C) coupler that extends two Ethernet patch cables without them being re-terminated. Consider it an instant, toolless splice for two pre-made cables.
Will a coupler slow down my network or break my link?
In general, no — a good-quality connection coupler is passive and won’t change the protocol speed. But every additional connection will add some signal loss, so you’ll want to use as few couplers as possible (and also read your Category rulebook; don’t stack couplers like a crazyperson if you need 10 Gbps).
Can I pass PoE (Power over Ethernet) through a coupler?
Sometimes — many of today’s even high-quality, modern cable in-line couplers will pass PoE; PoE++ on some certified models. But couplers introduce one more point of contact/resistance, so if you have really sensitive PoE devices it’s somewhat safer to go with the certified coupler or proper termination (wall jack / patch panel).
Do I have to match Cat5e/Cat6 couplers to my cables?
Yes — when you can, match the category and shielding of your cables to the coupler’s. A Cat6-rated shielded coupler with shielded cable maintains higher bandwidth and EMI protection; different ratings may work but low/no EMI performance loss is not guaranteed.
How do I use one correctly so it won’t cause problems?
Plug in two preterminated patch leads (with straight-through wiring), maintain the overall channel length under spec (this is usually just a maximum of 100 metres for typical Ethernet), don’t put it through kinks, and don’t daisy-chain too many connectors — that kind of thing minimises signal problems. Accept couplers as temporary convenience fixes and not permanent installations.
Are inline couplers reliable for long-term or permanent installs?
They can be OK for home/casual use, but for serious/long-term/reliable and/or high-speed installs, professionals prefer punch-down jacks or keystone plates (better mechanical contact and longer life). Use a coupler for temporary repairs to coax cables. “If you have to go the way of the coupler, spend a little money and get an organised-quality, category-rated one,” Raskin said.
