Advantech compatible SFP-GLX/LC-20E Description
EdgeOptic's SFP-GLX/LC-20E compatible is an Advantech-coded version of the EdgeOptic 1.25G-SFP-20D multi-vendor 1000BASE-LX 20 km transceiver. Advantech catalogs the SFP-GLX/LC-20E as a 1000BASE-LX 20 km single-mode SFP module rated for the 0 to 70 °C commercial temperature range, matching the underlying 1.25G-SFP-20D reach class and operating envelope on a single coded build.
The optical side follows IEEE 802.3z 1000BASE-LX on 9/125 µm single-mode fiber via duplex LC connectors at 1310 nm, with a 1260 to 1360 nm wavelength band. Transmit power is −9 to −3 dBm and receiver sensitivity is −24 dBm with a −3 dBm overload limit, giving 15 dB of link budget that supports the 20 km reach on standard G.652 fiber. The transceiver runs Gigabit Ethernet at 1.25 Gbps over the 0 to 70 °C commercial temperature range, draws power from a +3.3 V single supply, and exposes DDM/DOM telemetry so SFP-cage switch firmware can read live TX power, RX power, bias current, supply voltage, and module temperature.
The SFP-GLX/LC-20E sits in Advantech's industrial networking SFP line. The trailing E in the Advantech ordering code denotes the 20 km reach class, not extended temperature: the wide-temp industrial variant is the SFP-GLX/LCI-20E (−40 to 85 °C), a separate Advantech ordering code for harsh-environment deployments. Confirm the LC vs LCI prefix on the original part before swapping a module pulled from an industrial cabinet or DIN-rail switch, since the two are not interchangeable across the wide-temperature spec. The 10 km sibling pair SFP-GLX/LC-10E and SFP-GLX/LCI-10E follows the same commercial vs industrial naming convention at shorter reach.
This SFP-GLX/LC-20E compatible is one EEPROM build of the EdgeOptic 1.25G-SFP-20D platform, a single 1000BASE-LX 1310 nm 20 km SMF transceiver that ships under multiple vendor codings. The hardware is INF-8074i SFP MSA compliant, hot-pluggable, CE marked, RoHS compliant, and Class 1 laser safe per IEC 60825-1 and FDA 21 CFR 1040, so the EdgeOptic catalog covers the same optical build under Cisco, Juniper, Arista, HPE, Hirschmann, PLANET, Brocade, Check Point, and other vendor ordering codes for 1000BASE-LX 20 km SMF.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For industrial Ethernet SFP fit checks, wide-temperature SFP-GLX/LCI variant sourcing, or volume quotes, contact our sales team.
Frequently Asked Questions
What is the difference between the Advantech SFP-GLX/LC-20E and SFP-GLX/LCI-20E?
Both ordering codes describe a 1000BASE-LX 1310 nm 20 km single-mode SFP, and both share the same optical reach class. The only difference is the temperature range. The SFP-GLX/LC-20E is the standard 0 to 70 °C commercial-temperature module that this page covers. The SFP-GLX/LCI-20E is the wide-temperature industrial variant rated −40 to 85 °C, listed by Advantech as a separate ordering code for cabinet, DIN-rail, and harsh-environment deployments. The two are not interchangeable across the wide-temp spec, so engineers swapping a unit pulled from an outdoor enclosure or extended-temperature industrial switch should match the LCI prefix on the original part.
