It supports 10/100/1000Base-T links with zero packet loss over cable runs up to 200 meters, is USB-powered with inrush current protection, and fully compatible with Power-over-Ethernet. Ideal for IT pros needing reliable, portable, and secure traffic capture on PoE-enabled networks. ## Description The Dualcomm ETAP-2003 is a compact, rugged, and highly reliable Network TAP designed for monitoring and capturing network traffic on 10/100/1000Base-T Ethernet links. Housed in a durable metal enclosure, it is the smallest Gigabit Ethernet Network TAPs available, making it ideal for both portable and permanent deployment. The ETAP-2003 can be powered directly from a computer's USB port and incorporates a built-in inrush current limiting circuit to protect the host computer from excessive startup current. This design minimizes the risk of USB port interruptions or hardware damage caused by sudden current surges. The device is fully compatible with Power over Ethernet (PoE), allowing PoE power to pass transparently between the two in-line network ports without interruption. This capability makes the ETAP-2003 particularly well suited for monitoring traffic on PoE-enabled devices such as IP cameras, wireless access points, VoIP phones, and IoT equipment. As a dependable network monitoring and troubleshooting tool, the ETAP-2003 has been rigorously tested with a total in-line cable length of up to 200 meters while sustaining full Gigabit Ethernet throughput without packet loss. This performance makes it an excellent solution for portable packet capture, network diagnostics, performance analysis, and security monitoring. To enhance network safety, the monitor port blocks ingress traffic by default, preventing monitoring devices from accidentally injecting packets back into the production network. For applications requiring bidirectional communication through the monitor port, the ETAP-2003R variant is available. The ETAP-2003R operates identically to the ETAP-2003 except that ingress traffic on the monitor port is not blocked. With its compact form factor, PoE compatibility, robust construction, and reliable performance, the ETAP-2003 is an ideal solution for network engineers, security professionals, and IT administrators who need a dependable tool for monitoring and troubleshooting Gigabit Ethernet networks. ## Features - Network Tap for use with 10/100/1000Base-T Ethernet link - Reliable and high performance.

The manufacturer of this tap did the work to design and implement a device which would NOT change the characteristics or timing of the A/B traffic flow. The design is not a "standard cookie-cutter" implementation of a switch-chip's reference design. On the other hand, 5-port switches are as they say "a dime a dozen" and port mirroring and simple management protocols are now built into the silicon as standard features. Another reason for the price difference is the application. A tap is used in specialized circumstances, such as diagnostics or forensics, and that perhaps allows a higher price to be demanded, much like selling rope in a yachting goods store. The buying audience can bear a higher price. My explanation is just a conjecture. You have to decide if the special tap features are worth the money. **Q: Will it work with a cable modem?** A: It will work with any Ethernet cable. Standard stuff. I recommend CAT6 or better. It will not work with a coax cable like RG6. It is not managed and provides no services like DHCP. It is a simple layer 2 switch with a hardware mirrored port (1 -> 5). It is permanently configured this way. If you want to capture packets on the wire going traversing a gateway, then this is great for that. Otherwise, it will act just like a regular un-managed switch. **Q: If this device fails will it fail open or block all traffic?** A: With no power, it will not pass traffic. **Q: Thinking about by. Anyone who purchased notices any network degradation in their environment where they have implemented their Tap?** A: We have not had any noticeable network degradation. We positioned out tap on our outgoing broadband connection (70/40 Mbps down/up) and have not had any deleterious effects. ## Frequently Bought Together - Dualcomm ETAP-2003 10/100/1000Base-T Gigabit Ethernet Network TAP - LANProbe 10/100/1000 Gigabit Ethernet/USB Bypass Network Tap --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/75935052-dualcomm10-100-1000base-t-gigabit-ethernet-network-tap-etap-2003](https://www.desertcart.com.ar/products/75935052-dualcomm10-100-1000base-t-gigabit-ethernet-network-tap-etap-2003) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-15*
