Lantronix M/E-ISW-02 Hardened Mini Fast Ethernet Media Converters
The M/E-ISW-02 Series is a hardened mini media converter that links 10/100Base-TX copper to 100Base-FX fiber in outdoor cabinets and industrial enclosures, rated from -40°C to 75°C with no configuration required.

Overview
About the Lantronix M/E-ISW-02 Series
Edge devices in traffic cabinets, kiosks and plant-floor enclosures often sit beyond copper's 100 m reach and in temperatures that office converters cannot handle. The M/E-ISW-02 Series (also written ME-ISW-FX-02) solves both: it converts 10/100Base-TX to 100Base-FX fiber, operates from -40°C to 75°C, and measures just 46 x 85 x 22 mm, so it fits enclosures with little spare room. It is plug-and-play, with auto-negotiation and Auto-MDI/MDIX on the copper port and fixed full duplex on fiber.
Power enters through a 2-pin terminal block that accepts 12 to 48 VDC or 24 to 36 VAC, with overload current and reverse polarity protection. A barrel connector pigtail is included for external adapters. Consumption is 2.5 W. Link Pass Through, Far-End-Fault and automatic link restoration help detect and recover from link failures, and the SFP model adds Active Link Pass Through and 10,240-byte frames.
Fiber options cover multimode with ST, SC or LC connectors and single-mode with SC, plus an open SFP slot for other optics. Three LEDs on the RJ-45 face show power, fiber link and activity, and copper link and activity. A DIN-rail clip and velcro are included, and the WMBM wall-mount bracket is sold separately. The housing is IP20 rated and the unit carries FCC Class A and CE marks.
Key capabilities
- -40°C to 75°C rated
- Operating range of -40°C to 75°C and storage to 85°C let the converter run in outdoor cabinets and unconditioned industrial spaces.
- Wide AC or DC input
- The terminal block accepts 12 to 48 VDC or 24 to 36 VAC, with overload and reverse polarity protection, matching common industrial and security power sources.
- Tiny footprint
- At 46 x 85 x 22 mm, the mini converter fits space-constrained enclosures and mounts with the included DIN-rail clip or velcro.
- No configuration needed
- Auto-negotiation, Auto-MDI/MDIX and fixed full-duplex fiber make installation plug-and-play, with unit and port LEDs for quick status checks.
- Fault propagation
- Link Pass Through and Far-End-Fault signal link loss to connected equipment, and automatic link restoration brings the link back when the fault clears.
How to choose the right M/E-ISW-02 Series part number
The fiber interface is the only difference between models. M/E-ISW-FX-02 (ST) and M/E-ISW-FX-02(SC) use 1300 nm multimode to 2 km with a 14.0 dB budget. M/E-ISW-FX-02(MMLC) is 1300 nm multimode with LC connectors to 2 km and an 11.0 dB budget. M/E-ISW-FX-02(SM) uses 1310 nm single-mode on SC to 20 km with a 19.0 dB budget. M/E-ISW-FX-02(SFP) has an open 100Base-FX SFP slot and supports jumbo frames to 10,240 bytes. For mains power, add the SPS-UA12DHT 12 VDC adapter or the 25165 DIN-rail supply.

M/E-ISW-02 Series FAQ
What is the operating temperature of the M/E-ISW-02 media converter?
The M/E-ISW-02 Series operates from -40°C to 75°C and can be stored from -40°C to 85°C, at 5% to 95% non-condensing humidity. The housing is IP20 rated.
What power input does the M/E-ISW-FX-02 accept?
A 2-pin terminal block accepts 12 to 48 VDC or 24 to 36 VAC, plus or minus 10%. If your source does not match, the SPS-UA12DHT 12 VDC adapter or 25165 DIN-rail supply can be used, and a barrel connector pigtail is included.
Which M/E-ISW-02 model do I need for single-mode fiber?
M/E-ISW-FX-02(SM) is the fixed single-mode model, using 1310 nm on SC connectors to 20 km. For other single-mode distances or connectors, M/E-ISW-FX-02(SFP) accepts a 100Base-FX SFP of your choice.
Does the M/E-ISW-02 support jumbo frames?
Only the SFP version. M/E-ISW-FX-02(SFP) handles frames up to 10,240 bytes, while the fixed-fiber ST, SC, LC and single-mode models support a maximum frame size of 2,046 bytes.
How is the M/E-ISW-02 mounted?
A DIN-rail clip and velcro are included in the box. The WMBM wall-mount bracket, a 3.3-inch bracket that fits all Lantronix mini media converters, is sold separately. The compact 46 x 85 x 22 mm body suits crowded enclosures.
