Antaira LNX-0702G-SFP 7-Port Gigabit Unmanaged Industrial Network Switches with 2x SFP and Extended Temperature Options

A small cabinet with gigabit devices and a long run back to the core needs two things from its switch: full-speed copper and a fiber path that copper cannot match. The Antaira LNX-0702G-SFP series provides both in one unit, as industrial gigabit unmanaged Ethernet switches with five copper ports and two SFP slots, designed by Antaira for rugged and harsh environmental deployments. There is no management interface and nothing to configure, so the switch forwards traffic as soon as power is applied, which suits machine builders who want the network to stay out of the commissioning plan.

Every LNX-0702G-SFP shares the same design. The five 10/100/1000Base-T RJ45 ports 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 14 Gbps fabric with an 8K MAC table, 9.6 KB jumbo frames and IEEE 802.3x flow control, which leaves headroom for every port at line rate. Power arrives on 12 to 48 V DC redundant inputs with reverse polarity protection and an 8 W draw, and a relay output rated 24 V DC, 1 A signals a power failure.

The series has two builds. The LNX-0702G-SFP is the standard temperature model, rated -10 °C to 70 °C for heated or indoor cabinets. The LNX-0702G-SFP-T is the extended temperature model, rated -40 °C to 75 °C for unheated and outdoor enclosures. Ports, power and approvals are identical, so the choice follows the site. Where the copper devices only need Fast Ethernet, the LNX-0702C-SFP series keeps the same two SFP slots with 10/100 copper ports.

Both LNX-0702G-SFP models come in an IP30 metal case with DIN-rail and wall mounting hardware included, and follow IEC 60068-2-27 shock and IEC 60068-2-6 vibration testing. Antaira lists UL Class 1, Division 2 and UL 61010-1 certification, with FCC and CE marks and RoHS compliance, and covers the series with its 5-year warranty. The LNX-0702G-SFP series is a good fit wherever a gigabit device cabinet needs two fiber uplinks and no configuration. In practice, the two SFP slots let one switch serve a short multi-mode run inside a building or a long single-mode link to another site, depending on the transceivers fitted.
