The TP-Link ISM311LM 1000Base-SX Industrial SFP Transceiver is an SFP module for Gigabit Ethernet over multimode optical fibre. It supports 1000Base-SX at a data rate of up to 1.25 Gbit/s, making its rated throughput a relevant factor when matching a fibre link to network equipment. The module conforms to IEEE 802.3z and uses an 850 nm wavelength for optical transmission.
A duplex LC fibre interface provides the connection to the optical link. The specified maximum transmission distance is 550 m, which is worth considering when checking a proposed link path. The module is intended for industrial network installations that require fibre connectivity, and its operating temperature range suits installations with demanding temperature conditions. Check that the host equipment supports the SFP format and that the fibre link matches the module's 1000Base-SX and multimode specifications.
Key Features:- Operating temperature: -40 °C to 85 °C
- Hot-pluggable: can be inserted or removed without shutting down the host equipment
- Digital Diagnostic Monitoring (DDM): provides monitoring support
