Moxa SFP-1GLHLC-T Compatible 1000BASE-EX SFP Industrial Transceiver (SMF, 1310nm, 40km, LC, DOM, -40~85°C)
This Moxa SFP-1GLHLC-T compatible SFP industrial transceiver supports 1000BASE-EX Gigabit Ethernet connectivity and 1G fiber channel application. Featuring 1310nm wavelength, it supports a link distance of 40km over LC duplex single mode fiber (SMF). This 1G SFP transceiver complies with the SFP MSA, IEEE 802.3z, and SFF-8472 standards, making it suitable for any MSA-compliant equipment. Instead of an OEM supplier, it is produced by a third-party manufacturer, OPTCORE. Hence, this 1G SFP offers a very affordable price compared to the original SFP-1GLHLC-T.
Unlike the commercial transceiver, this 1G SFP EX industrial transceiver is made with hardened IC and optical components. It also passes extensive high and low temperature tests, allowing it to support an extended industrial temperature range of -40°C to 85°C. Therefore, it is ideal for industrial networks in harsh environments, including telecommunication, data processing and management, industrial and factory automation, machine control, surveillance, mining, oil and gas, rail, intelligent transportation systems (ITSs), and other outdoor applications.
