Description
Description
The TP-Link ISM311LM is a 1000Base-SX multi-mode industrial SFP module built to extend the reach of your industrial Ethernet switches over fibre. Supplied under SKU ISM311LM, it is part of the TP-Link ISM311 series, which also includes the ISM311LS 1000Base-LX single-mode variant. With an operating temperature range of -40°C to 85°C, it is designed for demanding environments where standard commercial modules may not be suitable.
Attached to compatible industrial switches, the ISM311LM can extend the distance to 550 m over multi-mode fibre, while its sister model, the ISM311LS, reaches up to 20 km over single-mode fibre. You can choose whether, and which, fibre modules to use according to demand, helping you keep costs under control.
