SFP-1GZXLC-T-BCC | Moxa Compatible 1GB Single-Mode ZR - 70km (1000BASE-ZX)

Q: Will this work in place of the Moxa SFP-1GZXLC-T?
A: Yes. This transceiver is coded and tested to operate as a direct replacement for the Moxa SFP-1GZXLC-T. It implements the same 1000BASE-ZX specification (1Gbps over single-mode fibre at 1550nm) and presents identical electrical and optical characteristics to the host platform. The module is plug-and-play compatible and will be recognized immediately upon insertion into any Moxa switch or platform that supports the SFP-1GZXLC-T.

Q: What Moxa switches and platforms support this transceiver?
A: This module is compatible with any Moxa Ethernet switch or industrial networking device that accepts standard SFP transceivers and lists gigabit single-mode support. This includes the ICS-G7000 and IM-G7000 interface module series, EDS-G508E/G512E/G516E managed switch families, IKS and EDS modular platforms with SFP slots, and similar Moxa industrial switches. If your platform has a gigabit SFP slot and supports single-mode optics, this transceiver will function correctly.

Q: What fibre type and grade do I need to reach 70 to 80km?
A: You need OS1 or OS2 specification single-mode fibre (9/125 micron core/cladding diameter) with LC duplex connectors. Actual reach depends on total link loss budget: OS1 fibre (1 dB/km attenuation) typically supports 70km; OS2 fibre (0.4 dB/km attenuation) can reach 80km or more. Factor in connector insertion loss (0.3 to 0.5 dB per mating pair) and splice loss if present. The 1550nm wavelength used by this transceiver experiences lower attenuation than 1310nm, enabling the extended reach.

Q: Can I access DDM data from this transceiver, and what parameters are available?
A: Yes. This module implements SFF-8472 digital diagnostic monitoring. You can read real-time optical transmit power, optical receive power, module temperature, supply voltage (3.3V rail), and laser bias current via the I2C interface exposed on pins 4 and 5 of the SFP connector. Most managed switches supporting DDM will display these values in the CLI or web UI. Monitoring receive power is especially useful on long 70 to 80km links to detect fibre degradation or margin erosion before link failure occurs.

Q: How does the -40 to 85°C operating range affect deployment compared to commercial-grade 0 to 60°C modules?
A: The extended industrial temperature range allows direct installation in outdoor enclosures, unheated roadside cabinets, rail wayside boxes, or factory environments subject to process heat without requiring climate control. The transceiver will maintain full 1Gbps throughput and meet all optical specifications across the entire -40 to 85°C span. Commercial-grade modules may experience optical power drift, increased bit error rates, or outright failure when exposed to temperature extremes outside the 0 to 60°C envelope.
