Cisco SFP Modules for Gigabit Ethernet Applications
The 2-channel 1000BASE-BX-D SFP module, also known as Compact SFP, integrates two IEEE 802.3ah 1000BASE-BX10-D interfaces in one SFP module. The GLC-2BX-D or GLC-2BX-D-I is

Choosing the Right SFP: Single Fiber vs Dual Fiber
Dual fiber SFPs are the traditional and more widely used type of optical transceivers. These modules use two separate fibers—one for transmitting and the other for receiving data.
What is the Difference Between Single Fiber and Dual Fiber SFP?
What is a Dual Fiber SFP Module? A dual fiber SFP module (also known as a two-fiber SFP module) is the more traditional design in fiber optics. As the name suggests, it uses two fibers:

Differences Between Dual Fiber SFP and Simplex SFP Modules
Dual fiber SFP modules are the commonly used 1G SFP module type. They operate on a bidirectional transmission mechanism and have two distinct channels or ports for transmission and reception of data.
Small Form-factor Pluggable
Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications.
