Introduction

Extreme Networks is a networking company that designs, builds, and sets up Ethernet computer network products for business and company grade (metro) networks while using speed and scale of 10 Gigabit Ethernet, 40 Gigabit Ethernet and 100 Gigabit Ethernet. Extreme Networks switches support both optical and copper SFP (small form factor pluggable) modules. The kinds of switches and the I/O modules determine the compatible type of SFP module. This paper will introduce the Extreme Network SFP modules and the matching switches. In addition, an alternative solution is provided here which could provide you with a cost effective option.

Kinds of Extreme Networks SFP Interfaces and Extreme Networks switches offer the following kinds of optical SFP interfaces:

SX SFP module

The SX SFP module supplies a 1000BASE-T optical connection using LC connectors and multimode fiber cable up to 300 meters long. The SX SFP module conforms to the 1000BASE-SX standard.

1000BASE-BX bidirectional SFP modules

The 1000BASE-BX SFP modules include the 1000BASE-BX-U SFP module and the 1000BASE-BX-D SFP module. Both of these SFP modules are used together to permit a bidirectional Gigabit Ethernet connection using a single strand of SMF cable and LC connectors. The 1000BASE-BX-D SFP operates at wavelengths of 1490 nm TX/1310 nm RX, and the 1000BASE-BX-U SFP operates at wavelengths of 1310 nm TX/1490 nm RX. The 1000BASE-BX-U SFP module is usually connected to the 1000BASE-BX-D SFP module. The maximum transmission distance for this connection is 10 km. The 1000BASE-BX SFP modules conform to the IEEE 802.3ah 1000BASE-BX10 standard.

10/100/1000BASE-T Copper SFP Module

The Extreme Networks 10/100/1000BASE-T Ethernet SFP module is compatible with the Gigabit Ethernet standard and 1000 Base-T standard as specified in the IEEE 802.3:2002 standard. This SFP module supplies a 100-Mbps connection using Category 5 cable.
