The Planet MGB-TLA20 is an industrial-grade Mini GBIC SFP optical transceiver designed for Gigabit Ethernet over single-mode optical fiber using 1000BASE-BX WDM technology. It features TX wavelength 1310 nm and RX wavelength 1550 nm, with a maximum transmission distance of 20 km, and supports digital diagnostic monitoring (DDM/DOM). The transceiver uses a simplex LC connector and operates over a wide temperature range from -40°C to 75°C, making it suitable for harsh and extensive industrial environments. It is hot-swappable and MSA-compliant, ensuring broad compatibility with PLANET industrial switches, media converters, and other networking devices supporting SFP. It typically includes an SFP transceiver.
