10GBASE-ER SFP+ Transceiver Modules

SFP-10G-ER supports up to 40km reach over single-mode fiber, while SFP-10G-ZR extends further, typically up to 80km. ZR modules generally use higher-powered lasers and more sensitive receivers to achieve this greater distance, making them suitable for metro or long-haul applications, whereas ER modules fit mid-range campus or data center interconnect needs.

An SFP (Small Form-factor Pluggable) module is a compact, hot-swappable transceiver used to connect networking equipment like switches and routers to fiber optic or copper networking cables. SFP modules support various protocols and data rates, including Gigabit Ethernet and Fibre Channel, and allow network administrators to customize port connectivity without replacing entire hardware units.

This SFP-10G-ER module is sold as used, tested networking equipment. It undergoes a comprehensive 5-step quality assurance and testing process before sale, ensuring it meets performance standards comparable to new equipment while offering significant cost savings over purchasing directly from Cisco Systems.

The SFP-10G-ER module is designed for compatibility with Cisco Systems networking equipment that supports the SFP+ form factor and 10GBASE-ER standard. Buyers should confirm compatibility with their specific switch or router model, and our technical support team can help verify fit before purchase.

Refurbished SFP-10G-ER modules purchased from Terabit Systems include a warranty backed by a replacement or full refund guarantee if the unit fails to perform as expected. RMA support is available throughout the warranty period for any defective units identified after installation.

A 10GBASE-ER SFP+ transceiver typically transmits 10 Gigabit Ethernet signals over single-mode fiber up to 40 kilometers, depending on fiber quality and installation conditions. This extended range makes it suitable for connecting facilities across a campus or linking data centers located in different buildings within a metropolitan area.
