Cisco SFP-10G-ER 10G ER SFP+ Transceiver Module

Equipment Overview

The Cisco SFP-10G-ER is a 10GBASE-ER SFP+ transceiver module designed for long-haul 10 Gigabit Ethernet connectivity in enterprise local area networks. This hot-swappable optical module enables high-speed data transmission over single-mode fiber, supporting distances typically associated with extended-reach applications. The unit is intended for deployment in Cisco switching and routing platforms that accept SFP+ form-factor optics, providing a reliable physical-layer solution for backbone links and inter-building connections.

Main Parameters

• Form Factor: SFP+ (Enhanced Small Form-Factor Pluggable)
• Ethernet Standard: 10GBASE-ER
• Maximum Reach: Extended range (40 km) over single-mode fiber
• Connector Type: Duplex LC
• Wavelength: 1550 nm (per 10GBASE-ER specification)
• Media Type: Single-mode fiber (SMF)
• Hot-swappable: Yes

Key Advantages

The SFP-10G-ER is selected for enterprise deployments requiring stable 10 GbE links over metropolitan-scale distances without intermediate amplification. Its standardized 10GBASE-ER interface ensures interoperability with existing single-mode infrastructure, while the SFP+ form factor allows dense port configurations in access and distribution switches. The module supports digital optical monitoring (DOM) capabilities, enabling real-time link diagnostics for proactive network management.

Compatibility & Integration

This transceiver is designed for Cisco equipment with SFP+ ports and complies with the IEEE 802.3ae 10GBASE-ER standard. It is compatible with the Cisco 10 GBASE SFP+ module series, ensuring seamless integration into enterprise LAN core and aggregation layers. The module adheres to MSA (Multi-Source Agreement) guidelines for SFP+ optical transceivers, facilitating deployment in mixed-vendor environments when Cisco qualification is not mandated.
