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

Product Description

The Cisco X2-10GB-ER is a 10GBASE-ER X2 optical transceiver module designed for enterprise local area networks and data center interconnectivity. This module enables extended-reach 10 Gigabit Ethernet connectivity over single-mode fiber, targeting B2B buyers requiring reliable long-haul links within metropolitan or campus networks. It is a field-replaceable X2 form-factor module compatible with Cisco switching and routing platforms supporting the X2 interface.

Technical Specifications

• Model: X2-10GB-ER
• MPN: X2-10GB-ER
• Form Factor: X2 module
• Interface Standard: 10GBASE-ER
• Data Rate: 10 Gbps (per 10GBASE-ER specification)
• Connector Type: Duplex LC (standard for X2 optical modules)
• Fiber Type: Single-mode fiber (SMF)
• Compatibility: Cisco equipment with X2 ports

Design Features

• Hot-swappable X2 form factor designed for minimal service disruption during installation or replacement.
• Optical transceiver integrates transmit and receive functions in a single module, simplifying cable management.
• Built for extended-reach performance, supporting long-distance fiber links per 10GBASE-ER specifications.
• Passive cooling design with no moving parts, enhancing reliability in dense chassis environments.
• Digital diagnostics monitoring (DDM) support for real-time optical parameter tracking (standard for Cisco X2 modules).

Application Area

This module is deployed in enterprise LAN cores, data centers, and campus backbone networks where high-bandwidth, extended-reach links (up to 40 km on single-mode fiber) are required between buildings or across metropolitan distances. It is suitable for interconnecting switches, routers, and storage systems over dark fiber or dedicated optical infrastructure. The X2-10GB-ER is typically used in aggregation and core layers where link distance exceeds the reach of standard 10GBASE-LR modules.
