Key Features of LINK-PP LS-SM3101-20I 155M SFP
LINK-PP LS-SM3101-20I is an industrial-grade single-mode optical transceiver designed for rugged environments operating between -40°C and +85°C. It integrates a 1310nm wavelength and duplex LC interface to ensure steady 155 Mbps data transmission up to 20km. This module balances reliable long-range connectivity with real-time digital monitoring capabilities.
LINK-PP LS-SM3101-20I 155M SFP Optical Module
This transceiver fully complies with the global SFP Multi-Source Agreement (MSA) for seamless hardware hot-swapping. It incorporates SFF-8472 digital diagnostics functions, allowing network operators to access vital internal telemetry. The standardized design guarantees broad, multi-vendor device compatibility.
LS-SM3101-20I: 155 Mbps Connectivity for Industrial Grid Systems
This module delivers a steady 155Mbps data rate tailored for Fast Ethernet and SDH/SONET applications. It provides the exact bandwidth required for automated utilities and industrial control networks. The fixed bit rate ensures low latency and predictable packet delivery across critical grid systems.
LS-SM3101-20I Module with 1310nm Wavelength
Operating at a centered 1310nm wavelength, this optical module utilizes a specialized FP laser to push light through single-mode fiber. The 1310nm window minimizes optical attenuation and dispersion, keeping the signal sharp over long distances. A matching PIN photodetector at the receiving end ensures clear signal capture.
LS-SM3101-20I Module Supporting 20km Transmission
Engineered for extended-reach infrastructure, this transceiver comfortably sustains data links across 20km of single-mode fiber cabling. Its robust optical power budget prevents signal loss over long outdoor runs between remote stations. This makes it an ideal choice for connecting widely separated industrial nodes.
LS-SM3101-20I Module with Duplex LC Interface
The module features a standardized duplex LC connector socket for secure fiber-optic patch cord latching. This dual-fiber interface separates the transmit and receive paths to allow full-duplex, simultaneous bidirectional communication. Its compact LC layout saves valuable port density on switches and media converters.
LS-SM3101-20I Module with DOM for Real-Time Monitoring
Equipped with built-in Digital Optical Monitoring (DOM), this module provides real-time tracking of internal operational parameters. Network administrators can instantly read transceiving power levels, laser bias current, module temperature, and supply voltage. This telemetry helps technicians detect potential link issues before a total network failure occurs.

We procured a large batch of these 155M SFP transceivers to maintain legacy SONET/SDH edge links for a regional telecom network. The dual LC connectors snap firmly into place, and the internal FP laser exhibits incredibly tight spectral tolerance at 1310nm. Across our 20km single-mode fiber footprint, optical loss remained safely within the module's engineered limits. Having true SFF-8472 diagnostic functions at this price point allows us to maintain strict carrier-grade SLAs without overspending on OEM-branded components.

We deployed 80 units of the LS-SM3101-20I across several remote water treatment facilities requiring deterministic 155Mbps connections. Utilizing single-mode fiber (SMF) over a 12km topology, the 1310nm FP laser combined with the PIN receiver yielded a remarkably stable power budget margin of over 6dB. The standout feature is the full SFF-8472 digital diagnostics implementation, allowing our centralized monitoring system to flag voltage or thermal fluctuations well before a link failure occurs. Exceptional hardware value for municipal infrastructure upgrades.
