The TN-GLC-GE-100FX is a hot-pluggable SFP transceiver for Fast Ethernet over multimode fiber. It belongs to the Lantronix TN-GLC-FE-100xX Series of Cisco-compatible 100Base SFP modules and uses a 1300nm optic on a duplex LC connector, reaching 2 km (1.2 mi) with an 8.5 dB link budget. The part number contains GE, but Lantronix lists this module as 100Base-FX, not Gigabit Ethernet. The series complies with the SFP Multi-Source Agreement (MSA), 100Base-FX and intermediate-reach SONET OC-3/SDH STM-1 (S-1.1), with IEEE 802.3 and IEEE 802.3ah listed as standards. The module draws 1.0 W from a 3.3 V supply and measures 13 x 55 x 8 mm (0.52 x 2.18 x 0.33 in). Standard modules operate from 0 °C to 70 °C, with a -40 °C to 85 °C storage range. Series certifications are IEC 60825 and FDA 21 CFR 1040.10 and 1040.11. Unlike the TN-GLC-FE-100FX, this part's listing carries no UL Listed note, and it is not one of the RGD variants with DMI. Lantronix lists applications including Fast Ethernet switches and routers, Fiber Channel switch infrastructure, xDSL applications and metro edge switching, and the series can be used on the xFMFF4040-100 optical line converter. Within the series, the TN-GLC-FE-100FX shares the same 1300nm multimode, 2 km rating, the TN-GLC-FE-100FX-RGD adds DMI and -40 °C to 85 °C operation, and the TN-GLC-FE-100LX (10 km) and TN-GLC-FE-100EX-RGD (40 km) cover 1310nm single-mode links.
