Overview
- The TP-Link ISM311LS and ISM311LM industrial SFP modules are purpose-built transceivers for demanding network environments where reliability and temperature resilience are critical. Available in single-mode (ISM311LS) for long-distance transmission and multi-mode (ISM311LM) for shorter fibre runs, both modules deliver Gigabit speeds over 1000Base-LX and 1000Base-SX fibre standards.
Designed to operate across an extended temperature range of -40 to 85°C, these modules excel in harsh industrial settings, outdoor installations, and remote locations where standard commercial-grade equipment would fail. The industrial-grade construction ensures consistent performance in challenging environmental conditions.
Digital Diagnostic Monitoring (DDM) provides real-time visibility into transceiver health, including optical power levels and temperature, enabling proactive network management and early fault detection. Hot-pluggable LC connectors allow quick module swaps without downtime, while full SFP-MSA compatibility ensures seamless integration with most network switches, routers, and optical equipment.
Backed by a 3-year warranty, these modules represent a cost-effective solution for organisations requiring industrial-strength fibre connectivity without premium pricing.

FAQs
What is the difference between the ISM311LS and ISM311LM models?
The ISM311LS is a single-mode transceiver (1000Base-LX) designed for long-distance fibre runs, typically up to 10 km. The ISM311LM is a multi-mode transceiver (1000Base-SX) suited for shorter distances, typically up to 550 m. Choose single-mode for long-haul links and multi-mode for backbone connectivity within a facility or campus.
Can these SFP modules be used in standard network equipment?
Yes. Both ISM311LS and ISM311LM modules are SFP-MSA compliant and will work with most standard network switches, routers, and media converters that feature SFP slots. However, always verify compatibility with your specific equipment manufacturer before purchasing.
What is Digital Diagnostic Monitoring (DDM)?
DDM allows real-time monitoring of transceiver health parameters such as optical transmit and receive power, temperature, and supply voltage. This enables network administrators to detect issues early, optimise performance, and troubleshoot problems remotely without physical access to the module.
Are these modules suitable for outdoor and harsh environments?
Yes. The industrial-grade operating temperature range of -40 to 85°C makes these modules ideal for outdoor deployments, remote facilities, and harsh industrial environments where standard commercial-grade transceivers would not operate reliably.
Can I hot-swap these modules without powering down equipment?
Yes. These modules are hot-pluggable, meaning you can safely insert or remove them while equipment is powered on and operational, providing flexibility for maintenance and configuration changes without network downtime.
What warranty coverage is included?
Both modules come with a 3-year manufacturer warranty covering defects in materials and workmanship. Hyetech Australia can provide warranty support and arrange replacement or repair if issues arise during this period.
