PLANET MGB-LX Compatible 1000BASE-LX 20km SFP

EdgeOptic's MGB-LX compatible is a PLANET-coded version of the EdgeOptic 1.25G-SFP-20D multi-vendor 1000BASE-LX 20 km transceiver. The OEM PLANET MGB-LX is rated 0 to +60 °C per the PLANET Technology product page; the EdgeOptic compatible runs to 0 to +70 °C under the underlying 1.25G-SFP-20D specification, so it covers the OEM's commercial-temperature application envelope on PLANET-branded Mini-GBIC slots across the GS, GSW, MGS, SGS, IGS, and WGS switch families that accept this SFP.

Optically the module follows IEEE 802.3z 1000BASE-LX on 9/125 µm single-mode fiber via duplex LC/UPC 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, delivering 15 dB of link budget for the rated 20 km reach. The transceiver runs Gigabit Ethernet at 1.25 Gbps, draws power from a +3.3 V single supply, and exposes DDM/DOM telemetry so PLANET switch software can read live TX power, RX power, bias current, supply voltage, and module temperature through the standard SFP two-wire interface.

PLANET uses the Mini-GBIC name in its product literature for what the SFP MSA defines as a standard SFP form factor, so the MGB-LX drops into any PLANET switch SFP cage. When sourcing, confirm the suffix on the original ordering code. The standard MGB-LX on this page is the commercial-temperature build; the MGB-TLX is the PLANET industrial variant for harsh-environment deployments (confirm the exact operating temperature on the PLANET MGB-TLX product page), and the MGB-L40 is a 40 km extended-reach variant. EdgeOptic stocks the industrial and 40 km variants under separate compatible part numbers.

This MGB-LX 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, Brocade, Check Point, and other vendor ordering codes for 1000BASE-LX 20 km SMF.
