TP-Link ISM311LS Industrial Gigabit Single-Mode SFP Module

Industrial Fibre Connectivity for a Gigabit Network The TP-Link ISM311LS brings 1000BASE-LX single-mode fibre connectivity to supported Gigabit SFP equipment. Designed for an industrial operating range of −40°C to 85°C, it suits installations where the optical module needs to work across a wider temperature range than ordinary office equipment. Its 1310nm optics, duplex LC/UPC connection and Digital Diagnostic Monitoring provide a straightforward building block for a properly matched fibre link. Highlights A Defined Fibre Connection 1000BASE-LX Gigabit Ethernet optics using 9/125µm single-mode fibre. Manufacturer reach up to 20KM, subject to the fibre link and optical budget. Industrial Module Design Operating range of −40°C to 85°C. Hot-pluggable SFP module with Digital Diagnostic Monitoring. Clear Host Requirements For compatible TP-Link switches with Gigabit SFP slots. Manufacturer installation guide also lists MC220L and MC420L media converters. Key Features Choose the Right Fibre Type This model uses single-mode fibre at 1310nm. Its single-mode optical link supports a manufacturer maximum of 20KM. The actual path must remain within the supported loss budget, including patch panels, joints and connectors. It is not interchangeable with a module intended for another fibre type simply because both use an LC connector. Match Both Ends of the Link The manufacturer recommends using the same transceiver model at each end, so a matching ISM311LS is the straightforward partner for this module. Use a correctly terminated duplex LC/UPC fibre pair. Unlike a bidirectional WDM module, this design uses separate transmit and receive fibres. Use a Supporting Gigabit Host The installation guide identifies TP-Link switches with Gigabit SFP slots and MC220L or MC420L media converters as compatible host categories. Check the exact device revision and supported module list. A module’s industrial temperature rating does not extend the temperature rating of its switch, converter, power supply or enclosure. Keep the Link Maintainable Hot-pluggable installation and Digital Diagnostic Monitoring support planned maintenance and fault investigation. A compatible host can display supported module readings alongside its interface status. Protect connectors from contamination, respect fibre bend limits and use normal ESD precautions when handling the module. Summary The ISM311LS is a practical industrial SFP option when single-mode fibre, Gigabit host support and the required link distance match the installation. Select matching remote optics and a suitable fibre path to build a dependable connection. Frequently Asked Questions Is 1.25Gbps the Ethernet speed?ExpandCollapse The module is for Gigabit Ethernet. The published 1.25Gbps figure is the encoded optical line rate, not a 1.25GbE host connection. Does it use one fibre or two?ExpandCollapse It uses a duplex LC/UPC connection with separate transmit and receive fibres. It is not a single-fibre bidirectional WDM module. Which module should be used at the other end?ExpandCollapse The manufacturer recommends the same transceiver model at each end. Use a matching ISM311LS and the correct fibre type and termination. Can I put it in any SFP or SFP+ port?ExpandCollapse No. The host must support the module at Gigabit speed. The guide lists TP-Link switches with Gigabit SFP slots and MC220L or MC420L media converters; confirm the exact revision and software support. Does the industrial rating apply to the whole network?ExpandCollapse No. The −40°C to 85°C figure applies to this module. The host, power supply and other installed equipment have their own operating limits. Baca selengkapnya
