Key Features of Cisco DWDM-SFP10G-43.73-I Compatible LINK-PP 10G SFP+

Cisco DWDM-SFP10G-43.73-I Compatible LINK-PP module is an industrial SFP+ DWDM module built to bridge optical distances up to 80km; it integrates standard 100GHz channel spacing with real-time digital monitoring to ensure stable, large-scale data transport across fiber networks.

Cisco DWDM-SFP10G-43.73-I Compatible LINK-PP 10G SFP+ Optical Module

This module uses a standard hot-pluggable SFP+ design that meets official MSA specifications; powered by a single +3.3V supply, it lets you plug in or replace units without turning off the switch.

DWDM-SFP10G-43.73-I: 10 Gbps Connectivity for High-Density Fiber Backhaul

Data transfer runs steadily at 10Gbps speeds across trunk and aggregation lines; this setup helps carry heavy traffic efficiently between remote cell sites and main network hubs.

DWDM-SFP10G-43.73-I Module with DWDM Technology for Fiber Efficiency

DWDM technology packs optical signals tightly using standard 100GHz spacing; by sending multiple data streams over a single fiber pair, it expands network capacity without laying new cables.

DWDM-SFP10G-43.73-I Module with 1543.73nm Wavelength

Channel C42 operates at an exact 1543.73nm wavelength to connect directly with matching optical multiplexers; this fixed frequency stops signals from overlapping or interfering with neighboring channels.

DWDM-SFP10G-43.73-I Module Supporting 80km Transmission

A built-in cooled EML laser and a sensitive APD detector work together to keep optical signals strong; this optical pairing lets data travel cleanly across 80km of single-mode fiber without extra signal boosters.

DWDM-SFP10G-43.73-I Module with Duplex LC Interface

The optical port uses an industry-standard duplex LC connector format; its push-pull latching mechanism ensures a firm, low-loss physical connection with single-mode patch cords.

DWDM-SFP10G-43.73-I Module with DOM for Real-Time Monitoring

Digital diagnostic monitoring tracks operating temperature, supply voltage, laser bias current, and optical power continuously; engineers can view these live values on their management software to spot fiber faults early.

Questions & Answers

No questions yet

Be the first to ask about specs, compatibility, or lead time.

Ask a Question
  • A:
    Yes, provided it has a compatible C42 (1543.73nm) channel port. Connect the DWDM module to the matching port and ensure the total link loss, including MUX/DEMUX insertion loss, stays within the available optical power budget. by LINK-PP Technical Support
  • A:
    For a conventional dual-fiber DWDM link using matching C42 MUX/DEMUX ports, yes—use C42 modules at both ends. Each module’s wavelength must match its corresponding MUX/DEMUX channel to ensure the optical signal passes through the intended path. by LINK-PP Technical Support
  • A:
    Yes. Its industrial operating temperature range of -40°C to +85°C makes it suitable for many outdoor cabinet applications, provided both the module and host equipment remain within their specified operating limits. The cabinet should also protect the module and host equipment from moisture, dust, and condensation. by LINK-PP Technical Support
  • A:
    Check the C42 Mux connections, fiber polarity, and optical power readings. Also confirm that the remote transceiver and switch settings are compatible. Incorrect patching or excessive fiber loss can prevent the link from coming up. by LINK-PP Technical Support

For our cellular backhaul project, we needed an optic suitable for long fiber spans and equipment cabinets exposed to changing temperatures. The -40°C to +85°C rating was a major consideration. The EML and APD optical design also fits our planned 10G transport links.

We manage several access switches across a business park. The C42 channel gives us another wavelength for extending our existing DWDM backbone. The 10GBASE-ZR/ZW support also matches our transport equipment requirements.
