The TP-Link ISM311LS & ISM311LM Industrial SFP Modules are high-performance, small form-factor pluggable transceivers designed for industrial networking environments requiring reliable, long-distance fiber connectivity. The ISM311LM model is a multi-mode 1000Base-SX LC transceiver operating at 850 nm wavelength, supporting data rates up to 1.25 Gbps with a maximum cable length of 550 meters on appropriate multi-mode fiber (MMF). The ISM311LS is the single-mode counterpart supporting 1000Base-LX at 1310 nm. Both modules comply with the Small Form-factor Pluggable Multi-Source Agreement (SFP-MSA) and support Digital Diagnostic Monitoring (DDM) to provide real-time module operating parameters.

Engineered for harsh industrial conditions, these modules operate reliably in a wide temperature range from -40°C to 85°C. They feature hot-pluggable design for easy insertion and removal without shutting down the system, ensuring maximum network uptime. Ideal for industrial automation, security surveillance, and harsh environment networking applications, these TP-Link SFP modules deliver robust and flexible fiber connectivity solutions.
