Cisco SFP-10G-ER 10GBASE-ER 1550nm 40km DOM SFP+ Transceiver

Cisco SFP-10G-ER

The Cisco SFP-10G-ER Transceiver provides a high-performance solution for 10 Gigabit Ethernet connectivity over extended single-mode fiber distances. This module operates at a nominal wavelength of 1550nm. It supports link lengths up to 40 kilometers on standard G.652 single-mode fiber (SMF). Consequently, it serves as a critical component for long-haul enterprise and service provider networks. The architecture utilizes a cooled EML laser and a high-sensitivity PIN receiver. This combination ensures reliable data transmission across significant spans without signal degradation. Therefore, network engineers can deploy this unit in core and aggregation layers effectively.

Why Choose This Module

• The hot-swappable design allows for installation or replacement without powering down the host switch or router.
• Low power consumption profiles minimize the thermal load on high-density line cards and switches.
• Additionally, the 40km reach eliminates the need for expensive intermediate repeaters in metropolitan area networks.
• Rigorous testing ensures interoperability with a wide range of Cisco platforms and third-party networking hardware.
• However, users must ensure the use of appropriate attenuators for short-distance testing to prevent receiver saturation.
