D-Link DIS-S310LX Industrial 1GbE Single-Mode SFP Transceiver

Fibre Connectivity Specified for the Link The DIS-S310LX is a 1GbE SFP optical transceiver for compatible network equipment. It uses a duplex LC connection and 9/125 µm single-mode fibre to support a specified reach of up to 10 km. Its industrial temperature rating supports protected factory, infrastructure and surveillance cabinets. Match the module to the host’s supported SFP port, fibre type and optical standard at both ends. The −40°C to 85°C operating range applies to the module; the whole installation must also stay within the ratings of the switch, cables and enclosure. A pluggable form factor does not by itself guarantee interoperability with every vendor or every port. Highlights Optical Connection 1GbE networking using an SFP module. Duplex LC fibre connection. Single-Mode fibre; up to 10 km specified reach. Link Specification 1310 nm optical wavelength. IEEE 802.3z; MSA and RoHS compliant. Hot-pluggable module for supported equipment. Physical Design Operating temperature −40°C to 85°C. 20 g module weight. 5-year warranty. Key Features Choose the Right Optical Medium This module is designed for 9/125 µm single-mode fibre. The link needs the correct cable, connectors and a matching optical specification at the other end. Assess the installed fibre and connector loss as well as route length before selecting the link. Match the Host Port The SFP form factor is intended for supported 1GbE equipment. Check the exact switch or adapter model, supported firmware, port mode and compatibility list. An SFP socket alone does not establish that every optical standard or module is supported. A Defined Fibre Link The optical interface uses 1310 nm light with duplex LC connectors. Two fibre paths carry transmit and receive traffic. Match the optical standard and link budget at both ends; this is not a single-fibre bidirectional module, a copper adapter or a cable that converts incompatible Ethernet standards. Temperature Rating Where It Matters The module operates from −40°C to 85°C. That wider industrial range is useful in protected equipment cabinets with variable temperatures. The switch, power system and fibre installation still need to be rated for the same site. Service a Supported Port Hot-pluggable construction allows insertion or replacement in equipment that supports the feature. Work on the affected link still interrupts that connection, so plan a maintenance window or a tested redundant path where necessary. Keep fibre end faces clean and use the protective caps when the module is not connected. Plan the Complete Optical Connection The offer is an optical module. Fibre patch leads, a second compatible endpoint and any required switch or adapter are separate. Before deployment, confirm connector type, optical loss, fibre grade and the host compatibility matrix so the complete connection is specified rather than relying on the module’s headline distance alone. Summary The DIS-S310LX gives supported 1GbE equipment a defined single-mode fibre connection with an industrial operating-temperature range. Select the correct host port, matching optical endpoint and fibre cable for a reliable installation. Frequently Asked Questions Which Fibre Type Does It Use?ExpandCollapse Use 9/125 µm single-mode fibre with duplex LC connectors. The manufacturer specifies a maximum reach of 10 km under the required link conditions. Will It Work in Any Pluggable Port?ExpandCollapse No. Confirm the host explicitly supports this 1GbE SFP module and the required port mode. A physically similar socket does not guarantee compatibility. Does It Use One Fibre Strand?ExpandCollapse No. It uses a duplex LC connection with separate transmit and receive fibre paths. It is not a single-fibre bidirectional module. Is It an Industrial-Temperature Module?ExpandCollapse Yes. The specified operating range is −40°C to 85°C. The host and the rest of the installation must also suit the site. Can It Be Replaced While the Switch Is Powered?ExpandCollapse It is hot pluggable when used in supported equipment. The affected link disconnects during replacement; plan maintenance or a redundant path if interruption matters. Are Fibre Cables Included?ExpandCollapse No. Fibre patch leads and the matching equipment or module at the other end are selected separately. Magbasa pa
