Cisco 10GBASE-ER Module X2-10GB-ER

CISCO GENUINE. BRAND NEW. FACTORY SEALED. FULL CISCO WARRANTY. FROM CHICAGO COMPUTER SUPPLY

Overview

When your network must push 10 Gigabit Ethernet over long distances, standard optics will not suffice. The Cisco X2-10GB-ER= is a high-performance 10GBASE-ER X2 transceiver module built for extended-reach links over single-mode fiber (SMF).

Operating at 1550nm and using a duplex LC connector, this module supports distances up to 40 kilometers, making it ideal for long-haul enterprise uplinks, service provider transport, and backbone connectivity between sites. It’s for environments where uptime matters and where stable, long-range 10G links keep the network running smoothly.

If you need a Cisco genuine 10G ER optic in the X2 form factor, this module delivers the reach and reliability you expect.
