It integrates a 1545.32nm wavelength, a 40km single-mode reach, and real-time digital monitoring via a duplex LC interface. This module provides reliable, high-capacity data transmission across demanding long-haul fiber architectures.
The module is fully compliant with industry standards, including the SFP+ MSA and SFF-8472 specifications. Built for harsh environments, it supports a wide industrial operating temperature range from -40°C to +85°C. This strict adherence to standards ensures seamless multi-vendor compatibility and reliable deployment in outdoor network nodes.
SFPP-10G-DW40-I: 10 Gbps Connectivity for Dense-Wavelength Aggregation
Delivering a reliable 10Gbps data rate, this module satisfies the intensive bandwidth demands of modern service provider networks. It is ideal for dense-wavelength aggregation in metro core platforms and regional telecom centers. The high data rate ensures smooth, continuous traffic flow through heavy distribution rings.
SFPP-10G-DW40-I Module with DWDM Technology for Fiber Efficiency
By utilizing Dense Wavelength Division Multiplexing (DWDM), this transceiver enables operators to maximize their existing fiber infrastructure without laying new cables. It splits a single fiber into multiple distinct channels, significantly increasing total network capacity. This makes it an incredibly cost-effective solution for expanding crowded fiber paths.
SFPP-10G-DW40-I Module with 1545.32nm Wavelength
The module operates at a precise fixed wavelength of 1545.32nm within the optical C-band spectrum. It features a stabilized cooled EML laser that prevents wavelength drifting under changing environmental conditions. This exact tuning ensures zero interference with neighboring channels in a dense optical grid.
Equipped with a high-sensitivity PIN photodiode, this module safely spans distances up to 40km over standard single-mode fiber.

Flawless compliance with SFF-8431 and MSA standards. As a hardware compliance engineer, I thoroughly check the EEPROM coding and physical layer parameters of all incoming network modules. The LS-DW4010-40I fully adheres to multi-source agreement specifications, offering wide-ranging compatibility across standard 10G line cards. Spectral analysis shows a highly stable center wavelength right at 1545.32nm with excellent side-mode suppression ratios (SMSR). The duplex LC/UPC interface ensures minimal back-reflection. It's rare to see third-party optical modules engineered with this level of precision and adherence to physical layer tolerances.

Excellent addition to our DWDM Mux/Demux setup. We needed some specific 1545.32nm 40km SFP transceivers to fill out a 40-channel grid. These duplex LC/UPC modules matched our channel spacing perfectly. No bit errors detected after a week of stress testing.

Delivery took an extra day, but the product is solid. Our shipping carrier delayed the delivery by 24 hours, which pushed our scheduled maintenance window back slightly. Once the modules arrived, installation was a breeze. The LS-DW4010-40I runs perfectly cool and the DDM diagnostics are fully accurate. Very satisfied with the hardware.

Tight fit on older legacy switch ports. The metal casing on these duplex LC units is built exactly to MSA specs, but it was a bit tight sliding them into our older, worn-out 10G line cards. Needed a firm push to click into place, but once seated, they linked up instantly at full 10G line speed.

Streamlined bulk deployment across data center interconnects (DCI). We recently upgraded our metropolitan DCI links to a 10G DWDM architecture to maximize existing dark fiber efficiency. We deployed 80 units of these Channel 40 SFP+ transceivers into our patch infrastructure. The immediate benefit was the low power consumption per port, which significantly reduces the aggregate heat dissipation across high-density 48-port switches. Digital Optical Monitoring (DOM) integration allows our operations center to set precise warning thresholds for RX optical power levels, enabling proactive maintenance before any physical link degradation occurs. A highly reliable, cost-effective infrastructure asset. (ノ￣▽￣)ノ

Solid choice for regional WISP backhaul. Deployed these modules on our rural tower sites where temperatures swing wildly. The industrial-grade rating (-40°C to 85°C) gives us huge peace of mind. Standard 10G SFP+ form factor fits snugly with no loose latches.

Solved our long-haul multi-campus latency bottlenecks. Our university network infrastructure links several campuses distributed over a 30km radius. Standard fiber runs were maxing out our bandwidth capacity. By utilizing these 1545.32nm 40km transceivers combined with a passive Mux/Demux, we multiplied our throughput capacity without trenching new physical fiber. The optical link budget easily overcame the attenuation from legacy outdoor splices. Latency is minimal, and packet transmission is perfectly stable.
