Key Features of LINK-PP LS-MM311G-02AC 1G SFP

LINK-PP LS-MM311G-02AC is a commercial-grade 1G SFP optical transceiver module designed to deliver stable 1310nm multimode fiber transmission up to 2km via a duplex LC interface. It combines standard hot-pluggable hardware compliance with real-time digital diagnostic monitoring to ensure dependable optical interconnects in enterprise environments.

LINK-PP LS-MM311G-02AC 1G SFP Optical Module

Engineered with a hot-pluggable SFP+ footprint, this optical transceiver module allows quick hardware installation and replacement without powering down host switches. The module fully complies with SFP+ MSA specifications, ensuring broad physical and electrical compatibility across standard networking platforms.

LS-MM311G-02AC: 1 Gbps Connectivity for Enterprise Switch Uplinks

Dedicated 1Gbps data throughput enables smooth traffic aggregation across enterprise access switches and distribution routers. This steady bandwidth handles daily corporate data transfers and critical server backbone links without introducing signal latency.

LS-MM311G-02AC Module with 1310nm Wavelength

A precise 1310nm central wavelength utilizes an FP laser transmitter to maintain optical beam clarity across multi-mode fiber cores. Operating at this specific optical window minimizes signal dispersion over longer multimode fiber installations compared to traditional 850nm links.

LS-MM311G-02AC Module Supporting 2km Transmission

Extended reach capabilities allow the optical link to span distances up to 2km over standard multi-mode fiber infrastructure. This transmission distance effectively bridges separate campus buildings and wide-area factory facilities without requiring expensive single-mode fiber upgrades.

LS-MM311G-02AC Module with Duplex LC Interface

The industry-standard duplex LC optical receptacle ensures secure fiber patch cable latching and low insertion loss. Its compact dual-port layout maximizes port density on high-count patch panels and core enterprise networking equipment.

LS-MM311G-02AC Module with DOM for Real-Time Monitoring

Internal digital optical monitoring provides live telemetry for optical power, supply voltage, laser bias current, and module temperature. Built-in compliance with SFF-8472 digital diagnostic functions allows network administrators to troubleshoot optical link health directly through switch software interfaces.

We used these to link two buildings over older multimode fiber. Our old 850nm optics failed because the distance was too long, but this 1310nm model handled the 1.5km run easily. Link is stable, optical power is great, and large file transfers never drop.

We installed eight LS-MM311G-02AC modules between office buildings on an older OM2 backbone. The 2km-rated 1G SFP gave us enough margin for the actual route, which is just under 1.4km. DOM values have been stable for three weeks =D
