100BASE-FX SFP Compatible Industrial Transceiver: 155M-SFP-2DI
100BASE-FX SFP Industrial Transceiver Overview
The 155M-SFP-2DI is a 100BASE-FX SFP transceiver built for industrial operating environments, rated from -40°C to +85°C. It transmits at 1310 nm over multi-mode fiber with a duplex Double LC/UPC connector pair, delivering up to 2 km of reach. The optical design pairs an FP laser transmitter with a PIN photodiode receiver, backed by a 19 dB average link budget. Transmit power ranges from -15 to -8 dBm, receiver sensitivity is -34 dBm, and receiver overload is -3 dBm. Wavelength bandwidth spans 1260 to 1360 nm, with the 1310 nm, multi-mode, 2 km 100BASE-FX operation following IEEE 802.3u. DDM/DOM monitoring is supported for visibility into transceiver operating parameters. The module also supports SDH/SONET STM-1 (155 Mbps) alongside 100M Ethernet, running on a single +3.3V supply. Compliance covers CE, Class 1 FDA and IEC 60825-1 laser safety, INF-8074i, RoHS and the SFP MSA.

100BASE-FX SFP Compatible Industrial Transceiver Description
The EdgeOptic 155M-SFP-2DI is a 100BASE-FX SFP transceiver engineered for industrial deployments, rated for continuous operation from -40°C to +85°C. It transmits and receives at 1310 nm over multi-mode fiber through a duplex Double LC/UPC connector, reaching up to 2 km per IEEE 802.3u.
The optical budget is set at 19 dB average link budget, with transmit power between -15 and -8 dBm and receiver sensitivity of -34 dBm against a -3 dBm receiver overload point. Wavelength bandwidth spans 1260 to 1360 nm (100 nm), and dispersion falls between 100 and 110 ps/nm. An FP laser transmitter pairs with a PIN photodiode receiver to hold that budget across the industrial temperature range.
Supported data rate spans 0.1 to 0.155 Gbps for dual-rate operation across 100M Ethernet and SDH/SONET STM-1 (155 Mbps) applications. DDM/DOM monitoring is supported for on-module diagnostics, and the module runs from a single +3.3V supply. Compliance includes CE, Class 1 FDA and IEC 60825-1 laser safety, INF-8074i and the SFP MSA, with RoHS-compliant construction.
The -40°C to +85°C industrial temperature rating is the difference between this module and EdgeOptic's standard-temperature 155M-SFP-2D, which is rated 0°C to 70°C; every other optical and electrical specification is shared between the two.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing or additional technical detail, contact our sales team.
Frequently Asked Questions
What is the difference between the 155M-SFP-2DI and the standard-temperature 155M-SFP-2D?
The 155M-SFP-2DI is rated for industrial operation from -40°C to +85°C, while the 155M-SFP-2D carries a standard 0°C to 70°C temperature rating. Every other optical and electrical specification, including the 19 dB link budget, 1310 nm wavelength and 2 km reach, is shared between the two modules. Order the 155M-SFP-2DI for outdoor cabinets, uncontrolled equipment rooms or other environments outside the standard commercial temperature band.
