Key Features of Generic DW-SFP10G40-33-I Compatible LINK-PP 10.7G SFP+
Generic DW-SFP10G40-33-I Compatible LINK-PP combines industrial-grade durability (-40°C to +85°C) with 10G DWDM optics on the 1550.92nm C-band channel to reach 40km over single-mode fiber. It incorporates duplex LC optics and internal diagnostic telemetry within a compact hot-swappable frame. This architecture enables efficient, high-density fiber expansion across rugged infrastructure without laying new cable routes.
Built on an industry-standard hot-pluggable form factor, this transceiver supports live system maintenance and rapid field upgrades. The optical engine utilizes a cooled Electro-absorption Modulated Laser (EML) paired with a high-sensitivity PIN receiver for clean signal integrity over long spans. Its hardened internal components guarantee continuous uptime in harsh outdoor environments.
DW-SFP10G40-33-I: 10 Gbps Connectivity for High-Density Optical Backbones
Delivering full 10G line rate capability, this module satisfies heavy throughput requirements across core switching matrices. It excels in metro aggregation nodes, utility communication networks, and dense campus interconnections. The high bandwidth density allows operators to scale network capacity smoothly without increasing rack footprints.
DW-SFP10G40-33-I Module with DWDM Technology for Fiber Efficiency
Dense Wavelength Division Multiplexing enables dozens of independent data streams to travel simultaneously over a single strand of fiber. By multiplexing channels on tightly spaced ITU-T grid frequencies, operators can scale total system bandwidth by multiples. This significantly maximizes existing dark fiber assets while cutting dark-fiber leasing and deployment overhead.
DW-SFP10G40-33-I Module with 1550.92nm Wavelength
Fixed precisely on the 1550.92nm ITU grid channel (C33), this optical module operates within a lower attenuation window of single-mode fiber. Operating at this specific optical band minimizes signal degradation and dispersion penalties over mid-to-long reaches. It provides precise channel alignment necessary for seamless integration into active optical multiplexers.
Designed with a strong optical power margin, this module establishes direct 40km point-to-point connections over single-mode fiber. It eliminates the need for intermediate optical amplifiers or signal regenerators in suburban and regional spans. This extended reach simplifies link architecture while reducing active equipment points of failure.
DW-SFP10G40-33-I Module with Duplex LC Interface
Featuring a standardized duplex LC connector, the module couples smoothly with industry-standard fiber patch cords and patch panels. The dual-LC mechanical latching mechanism ensures a secure physical link and low insertion loss. Its compact interface geometry is optimized for ultra-dense switch chassis where panel space is at a premium.
DW-SFP10G40-33-I Module with DOM for Real-Time Monitoring
The built-in Digital Optical Monitoring capability provides real-time telemetry into critical physical-layer metrics. Network operators can remotely evaluate optical transceiver temperature, laser bias current, transmit output power, optical receive power, and internal supply voltage. These dynamic diagnostics enable early fault detection and streamline proactive preventive maintenance.
Generic DW-SFP10G40-33-I Compatible LINK-PP module is fully certified under ISO 9001, CE, RoHS, and FCC standards to ensure international environmental compliance, electrical safety, and superior manufacturing quality.
Every module undergoes thorough multi-stage factory inspections to ensure long-term operational stability.
