The DWDM-SFP-4851-C supports a link length of up to 80 km over standard single-mode fiber (SMF).
It operates precisely at 1548.51 nm for dense wavelength-division multiplexing (DWDM) applications.
Yes, it is fully compatible with Cisco platforms and passes Cisco authenticity checks.
This module uses the standard SFP (small form-factor pluggable) footprint.
It supports a data rate of 1.25 Gbps for Gigabit Ethernet links.
Single-mode fiber (ITU-T G.652 compliant) is required for optimal performance.
With a typical transmit power of +0.5 dBm and receive sensitivity of –24 dBm, the power budget is 24.5 dB.
It operates between 0 °C and 70 °C (32 °F to 158 °F) ambient temperature.
Yes, it is compliant with SFF-8472 digital diagnostics monitoring for real-time performance data.
Insert the module into an SFP port until it clicks, then enable and configure the interface in your CLI or GUI.
Yes, it supports hot-plug installation and removal without powering down the system.
The module’s receiver sensitivity is –24 dBm, ensuring robust signal detection.
It includes a one-year limited warranty, with extended support options available upon request.
Ideal for long-haul Gigabit Ethernet, Metro DWDM rings, and service-provider networks.
DWDM uses narrower channel spacing (0.8 nm) for higher channel count, while CWDM uses wider spacing (20 nm) for cost-effective deployments.
Key features include 1.25 Gbps rate, 1548.51 nm wavelength, 80 km reach, Cisco compatibility, DDM support, and hot-swap capability.
