Overview
About the Lantronix TN-10GSFP-LRxM Series
Most 10G SFP+ optics run at a single rate. The TN-10GSFP-LRxM Series (part numbers TN-10GSFP-LR1M, TN-10GSFP-LR4M and TN-10GSFP-LR8M) is multi-rate: each module supports 10GBase-LR or ZR at 10.3 Gbps and 1000Base-LX or ZX at 1.25 Gbps. That lets one spare type cover both 1G and 10G single-mode links, or keep a link running at 1G until the far end is upgraded to 10G.
The three models are distinguished by wavelength and reach. The LR1M uses 1310 nm to 10 km with a 9.0 dB link budget, the LR4M uses 1550 nm to 40 km with 15.0 dB, and the LR8M uses 1550 nm to 80 km with 22.0 dB. All use duplex LC connectors, run from a single +3.3 V supply, and comply with SFF-8431 and SFF-8432 mechanical and electrical specs.
SFF-8472 digital diagnostics (DMI) report optical and operating values to the host switch for link monitoring. Modules support bidirectional data links up to 10.5 Gbps, operate from 0°C to 70°C, store from -40°C to 85°C, measure 13 x 56 x 8 mm, and carry IEC-60825 and CFR 1040.10/1040.11 laser safety compliance.
Key capabilities
- Dual-rate 1G/10G operation
- Each transceiver supports 10GBase-LR/ZR at 10.3 Gbps and 1000Base-LX/ZX at 1.25 Gbps on the same single-mode optics.
- Reach up to 80 km
- Pick 1310 nm for 10 km, or 1550 nm for 40 km or 80 km, with link budgets of 9.0, 15.0 and 22.0 dB.
- DMI diagnostics
- SFF-8472 digital diagnostics let the host switch monitor optical and operating values to spot fiber or module problems early.
- MSA-compatible SFP+
- Compliant with the SFP+ MSA and the SFF-8431/8432 specifications, so the modules fit standard SFP+ ports and are RoHS compliant.
How to choose the right TN-10GSFP-LRxM Series part number
The digit in the part number is the reach class. TN-10GSFP-LR1M is 1310 nm, 10 km, 9.0 dB budget, for 10GBase-LR and 1000Base-LX. TN-10GSFP-LR4M is 1550 nm, 40 km, 15.0 dB, also LR/LX. TN-10GSFP-LR8M is 1550 nm, 80 km, 22.0 dB, for 10GBase-ZR and 1000Base-ZX. Choose the shortest-reach model whose budget covers your measured span loss, and pair modules of the same type at each end of the link.

TN-10GSFP-LRxM Series FAQ
Does the TN-10GSFP-LR1M work at 1 Gbps?
Yes. All TN-10GSFP-LRxM modules are multi-rate. The LR1M supports 10GBase-LR at 10.3 Gbps and 1000Base-LX at 1.25 Gbps over 1310 nm single-mode fiber up to 10 km, so it can link to 1G or 10G equipment.
What is the difference between TN-10GSFP-LR4M and LR8M?
Both use 1550 nm on single-mode LC fiber. The LR4M is a 10GBase-LR/1000Base-LX module reaching 40 km with a 15.0 dB link budget. The LR8M is 10GBase-ZR/1000Base-ZX, reaching 80 km with a 22.0 dB budget.
Do these SFP+ modules support digital diagnostics?
Yes. All three support SFF-8472 digital diagnostic monitoring (DMI), so compatible switches can read optical and operating values from the module for monitoring and troubleshooting.
What is the operating temperature of the TN-10GSFP-LRxM?
0°C to 70°C operating and -40°C to 85°C storage. The modules run on a single +3.3 V supply and measure 13 x 56 x 8 mm.
