ETAP-2003 i olidly contructed with a metal cae and i probably the mallet in ize of all the GbE Network Tap available on the market. ETAP-2003 can be powered from a computer' UB port with built-in inruh current limiting circuit to prevent the computer from poible damage or diturbance by an intantaneou current urge when ETAP-2003 i being powered from a UB port of the computer. ETAP-2003 i compatible with \Power over Ethernet\ (PoE) o that deployment of an ETAP-2003 Network Tap would not block the end-to-end flow of PoE inline power which i a very ueful feature for monitoring or capturing data traffic of a PoE Ethernet link. A network monitoring and troublehooting intrument ETAP-2003 i highly reliable with conitence performance. It has been teted with the maximum in-line cable length of 200 m at a full 1Gbp data throughput with no ingle packet lo. All thee make ETAP-2003 an ideal portable network traffic niffing device for monitoring and troublehooting data traffic in a 10/100/1000Bae-T Ethernet network. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***E on October 6, 2015* ### ⭐⭐⭐⭐⭐ Review *by N***A on October 18, 2012* ### ⭐⭐⭐⭐ Review *by J***H on February 1, 2026* ## 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.tn/products/75935052-dualcomm10-100-1000base-t-gigabit-ethernet-network-tap-etap-2003](https://www.desertcart.tn/products/75935052-dualcomm10-100-1000base-t-gigabit-ethernet-network-tap-etap-2003) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
