Key Features of LINK-PP LS-DW1910-40I 10G SFP+
LINK-PP LS-DW1910-40I is an industrial-grade 10G DWDM optical transceiver built for long-reach metro connectivity and high-density fiber networks. It pairs a precise 1562.23nm wavelength engine with real-time digital optical monitoring over a 40km duplex LC single-mode fiber link. This combination delivers scalable, reliable bandwidth across demanding operational environments.
LINK-PP LS-DW1910-40I 10G SFP+ Optical Module
Built on a hot-pluggable SFP+ footprint, this module simplifies field deployment and hardware upgrades without interrupting active switch operations. Inside, a cooled EML laser tuned to the 100GHz ITU C-Band grid works alongside a sensitive PIN photodiode. Together, they maintain strict optical stability and clean signal delivery over extended distances.
LS-DW1910-40I: 10 Gbps Connectivity for Metro Optical Links
Delivering a sustained 10Gbps transmission rate, this transceiver provides the essential throughput required for modern data-heavy networks. It is ideal for metro core links, regional campus backbones, and enterprise edge aggregations. Network operators rely on this fixed-rate capacity to clear bandwidth bottlenecks across urban fiber rings.
LS-DW1910-40I Module with DWDM Technology for Fiber Efficiency
By using Dense Wavelength Division Multiplexing (DWDM), the module multiplexes multiple data channels over a single physical fiber pair. This capability enables operators to multiply network capacity without laying new optical cable. As a result, it significantly lowers infrastructure costs while maximizing existing fiber utilization.
LS-DW1910-40I Module with 1562.23nm Wavelength
Operating on the specific 1562.23nm C19 channel within the ITU-T grid, the transmitter minimizes inter-channel crosstalk in multi-channel setups. Its stable optical output ensures precise alignment in complex DWDM multiplexer and demultiplexer systems. This fixed wavelength targeting guarantees seamless integration into standardized optical line cards.
LS-DW1910-40I Module Supporting 40km Transmission
Engineered for intermediate-reach connectivity, the transceiver supports link distances up to 40km over standard single-mode fiber (SMF). Its high optical power budget overcomes attenuation barriers across long fiber runs without extra signal amplification. This makes it an efficient solution for bridging distributed data centers and remote central offices.
LS-DW1910-40I Module with Duplex LC Interface
Featuring an industry-standard duplex LC connector interface, the module ensures low insertion loss and secure physical patching. Its compact design fits dense switch port layouts while maintaining reliable fiber retention. This simple interface layout speeds up installation and standardizes cabling across patch panels.
LS-DW1910-40I Module with DOM for Real-Time Monitoring
Integrated Digital Optical Monitoring (DOM) gives network admins live visibility into critical physical-layer metrics. The system continuously tracks operating temperature, laser bias current, supply voltage, and optical Rx/Tx power levels. Early fault detection via DOM helps prevent unscheduled downtime and speeds up link troubleshooting.

Our operations team tested this LS-DW1910-40I 10G DWDM module for an edge-network aggregation project. The important part was not just link-up—we needed visibility into module health after installation in field cabinets. The module’s SFF-8472 DOM/DDM data let us monitor optical TX/RX power, voltage, and temperature remotely, which reduced unnecessary truck rolls. We also ran Ethernet traffic tests during commissioning, and the link stayed stable under normal production load.

We put these LS-DW1910-40I C19 DWDM modules through a rigorous bench test before deploying them into our multi-site DWDM ring architecture. Using an optical spectrum analyzer and OTDR across a long-haul single-mode fiber link, the optical launch power and receiver sensitivity stayed well within design margins, yielding an excellent OSNR buffer. DOM reporting via SNMP integrates directly into our NMS dashboard, providing real-time Tx/Rx power, laser bias current, and temperature metrics. Outstanding optical stability for high-density 10G enterprise networks!

Deploying 10G DWDM optics in unconditioned outdoor cabinets is always tricky due to severe thermal swings, but these industrial-grade 1562.23nm 40km SFP+ transceivers handled our field conditions with flying colors. We ran a 48-hour loopback benchmark at full 10Gbps line rate across a 32km field link. Zero frame loss, steady jitter, and thermal readings hovered around 48°C inside a sealed enclosure under direct afternoon sunlight. The metallic enclosure provides exceptional heat dissipation and EMI protection.

Our remote industrial monitoring nodes operate under extreme ambient temperature ranges from freezing sub-zero nights to warm summer afternoons. We swapped out standard commercial SFP+ modules for these industrial-grade C19 1562.23nm DWDM transceivers on our fiber ring topology. Bit Error Rate tests consistently remained well below the 10⁻¹² threshold. The physical bail latch is durable, electrical isolation is solid, and hot-swapping didn't disturb neighboring active ports on the switch blade.
