Description

An extended-reach 10 gigabit optic using a 1550 nm laser for single-mode spans up to 40 km. It serves metro rings, inter-site data-centre links and utility routes that exceed the 10 km LR limit but not 80 km. Cisco's datasheet advises a 5 dB attenuator on links shorter than 20 km. Cabling is duplex G.652 fibre with LC PC or UPC ends. The SFP-10G-ER is a SFP+ form-factor part for SFP+ ports on 10 gigabit switches, routers and server adapters. It runs over a duplex fibre pair and is specified for the commercial temperature range of 0 to 70 degrees Celsius. Its listed reach is 40 km on SMF. Check the link budget against the real fibre plant, including connectors and splices, before relying on the headline distance. Because compatibility is decided per platform and software release, confirm the exact host device in the Cisco compatibility matrix before ordering.

Typical uses

Metro and long-haul links between sites
Service-provider aggregation over dark fibre
Long campus spans beyond the 10 km class

Before you order

Confirm your switch or router model and software release support the SFP-10G-ER=
Use single-mode (OS2) fibre and check the link budget for the full span
On short test links an attenuator may be needed to avoid overloading the receiver
Prices exclude import duties and taxes in your country (DAP)
