Antaira LNX-1802G-SFP 18-Port Gigabit Unmanaged Industrial Ethernet Switches with 2x SFP and Extended Temperature Options

A large surveillance or vision cabinet usually has many gigabit devices and only a couple of long links back to the control room. The Antaira LNX-1802G-SFP series is shaped around that: industrial gigabit unmanaged Ethernet switches with 16 copper ports and two SFP slots, which Antaira describes as ideal for high-density port connections with wide network bandwidth. There is no management interface and nothing to configure, so the switch forwards traffic as soon as it is powered, and every copper port runs at full gigabit speed.

Every LNX-1802G-SFP shares the same design. The 16 RJ45 ports at 10/100/1000Base-T support auto negotiation and auto MDI/MDI-X, and the two dual-rate SFP slots take 100 or 1000 Mbps transceivers, so fiber mode and reach follow the modules chosen. Switching is unmanaged and store-and-forward on a 36 Gbps fabric, enough for every port at line rate, with an 8K MAC table, a 4 Mbit buffer, 9.6 KB jumbo frames and IEEE 802.3x flow control. Power arrives on 12 to 48 V DC redundant inputs with reverse polarity protection and a slow-blow fuse, the switch draws a maximum of 15 W at full load, and a relay rated 24 V DC, 1 A warns of a power redundancy failure.

The series has two builds. The LNX-1802G-SFP is the standard temperature model, rated -10 °C to 65 °C for heated or indoor cabinets. The LNX-1802G-SFP-T is the extended temperature model, rated -40 °C to 75 °C for unheated and outdoor enclosures. Both share ports, power and approvals. Where four fiber links are needed, the LNX-2004G-SFP series keeps 16 copper ports and doubles the SFP slots.

Both LNX-1802G-SFP models come in an IP30 metal case for DIN-rail or wall mounting, and follow IEC 60068-2-27 shock and IEC 60068-2-6 vibration testing. Antaira lists UL 61010-1 certification, with FCC and CE marks and RoHS compliance, and covers the series with its 5-year warranty. Antaira names security video surveillance, GigE machine vision, process control automation and intelligent transportation as applications where the LNX-1802G-SFP series works well. In practice, two SFP slots give a large cabinet a main and a second fiber uplink, with the mode and reach of each set by the transceiver fitted.
