Features and benefits
Main features of Cisco 10GBASE SFP+ modules include:
● Smallest 10G form factor
● Commercial temperature (-5 to 85°C) only
● Supports 10GBASE Ethernet only
● Hot-swappable input/output device that plugs in to an Ethernet SFP+ port of Cisco platforms
● Provides flexibility of interface choice
● Supports digital optical monitoring capability
● Cisco quality identification (ID) feature that enables a Cisco platform to identify - optics supported by Cisco technology
● Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link
 
Cisco SFP-10G-SR-X module
The Cisco SFP-10G-SR-X is a multirate* 10GBASE-SR, 10GBASE-SW and OTU2/OTU2e module for extended operating temperature range. It supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.
