The WS-SFP-LX-C is a Cisco-compatible 1000BASE-LX small form-factor pluggable (SFP) transceiver designed for single-mode fiber applications up to 10 km.
Yes, the WS-SFP-LX-C module is rigorously tested for full interoperability with Cisco WS-X4448-GB-LX line cards and other Cisco SFP-capable switches.
This SFP supports single-mode fiber (SMF) at a transmit wavelength of 1310 nm for reliable long-distance connectivity.
The WS-SFP-LX-C reliably transmits data up to 10 kilometers over single-mode fiber at 1 Gbps data rate.
It supports a Gigabit Ethernet data rate of 1.25 Gbps, fully compliant with IEEE 802.3z standards.
Yes, the WS-SFP-LX-C module is hot-pluggable, allowing you to install or remove it without interrupting network operations.
The WS-SFP-LX-C is compatible with Cisco Catalyst 2950, 2960, 3550, 3750, 4500, 6500 series and Cisco 7600 series switches.
This module uses an LC duplex connector for secure fiber strand termination and minimal insertion loss.
The WS-SFP-LX-C operates between 0°C and 70°C (32°F to 158°F) for standard commercial applications.
The WS-SFP-LX-C offers an MTBF of over 1 million hours, ensuring high reliability in enterprise networks.
Yes, this module includes a one-year limited warranty covering manufacturing defects and performance compliance.
The WS-SFP-LX-C is certified for CE, FCC, RoHS, and ISO 9001 standards to ensure safety and environmental compliance.
To install, gently insert the WS-SFP-LX-C into the SFP port until it clicks, then connect the LC fiber cable and verify link status via the switch interface.
Ideal for campus backbone, data center interconnects, and metro Ethernet deployments requiring cost-effective 10 km fiber links.
Unlike 1000BASE-SX, which uses multimode fiber at 850 nm for short distances, the WS-SFP-LX-C uses single-mode fiber at 1310 nm for up to 10 km reach.
Yes, the WS-SFP-LX-C is interoperable with industry-standard SFP transceivers, but consistent labeling and monitoring are recommended for best performance.
