The DWDM-SFP-3898-120-C is a Cisco-compatible 1000BASE-DWDM SFP transceiver operating at 1538.98nm for up to 120 km over single-mode fiber.
This module transmits at a precise DWDM wavelength of 1538.98 nm, ensuring minimal channel interference in dense wavelength division multiplexing systems.
It supports links up to 120 km over standard single-mode fiber (SMF) with an optical budget optimized for long-haul DWDM applications.
Yes, it is fully Cisco-compatible and interoperable with Catalyst, Nexus, ASR, and other Cisco routers and switches without requiring firmware upgrades.
The transceiver supports a data rate of 1.25 Gbps (1000BASE-DWDM), ideal for Gigabit Ethernet and 1G Fibre Channel applications.
It features an LC duplex connector, providing a secure and industry-standard interface for single-mode fiber connections.
The module requires ITU-T G.652-compliant single-mode fiber to achieve optimal performance over distances up to 120 km.
Yes, the SFP transceiver is hot-swappable, allowing installation and removal without powering down your network device.
The module operates reliably between 0 °C and 70 °C (32 °F to 158 °F), suitable for standard commercial environments.
Transmit power ranges from –5.0 to +0.5 dBm and receive sensitivity is –24.0 dBm, providing a robust optical link budget for long-haul transmission.
