SFP-1GLHXLC-T-BCC | Moxa Compatible 1GB Single-Mode ER - 40km (1000BASE-EX)

Q: Will this work in place of the Moxa SFP-1GLHXLC-T?
A: Yes. This transceiver is designed as a direct replacement for the Moxa SFP-1GLHXLC-T. It matches the same 1000BASE-EX specification, 1310nm wavelength, 40km single-mode reach, LC connector, and industrial -40 to 85 degrees C temperature range. It is plug-and-play compatible and programmed to the same MSA standard with DDM support.

Q: Which Moxa switches and platforms support this transceiver?
A: This transceiver works in any Moxa switch or device with SFP slots that support 1000BASE-X standards, including the ICS-G7000, ICS-G7500, ICS-G7800, IKS-G6500, EDS-G500, and EDS-500A series industrial Ethernet switches. Compatibility is based on the IEEE 802.3z standard, not on specific platform models. If your Moxa device accepts gigabit SFP modules and operates on single-mode fiber, this module will function.

Q: What fiber type and connector are required for 40km reach?
A: You need 9/125um single-mode fiber (OS1 or OS2 grade) with LC duplex connectors. The 40km reach assumes clean fiber with low insertion loss, minimal splices, and appropriate optical budget. Multimode fiber is not supported for this module. Standard SMF patch cables with UPC or APC polish are suitable. For spans approaching 40km, verify your fiber plant insertion loss is within the module's power budget.

Q: How does the industrial temperature range affect deployment?
A: The -40 to 85 degrees C rating allows this transceiver to operate in non-climate-controlled environments such as outdoor telecom cabinets, railway signal houses, roadside ITS enclosures, and industrial control rooms without HVAC. Standard commercial transceivers are rated 0 to 70 degrees C and will fail or throttle in extreme cold or heat. The extended range is critical for rail, oil and gas, mining, and utility applications where equipment operates in ambient conditions.

Q: Can I access DDM parameters on any platform, and what do they indicate?
A: DDM data is available on any host platform that supports SFF-8472 querying via the SFP I2C interface. Most managed industrial switches, including Moxa ICS and EDS series, expose DDM through CLI or web UI. The five monitored parameters are transmit optical power, receive optical power, module temperature, supply voltage, and laser bias current. Degrading receive power or rising bias current can indicate fiber contamination or aging lasers, allowing you to replace the module or clean connectors before a link failure occurs.
