What Is the Difference Between a Gigabit Optical Module and a 10 Gigabit Optical Module?

Gigabit optical modules and 10 Gigabit optical modules have obvious speed differences in actual use. This article will explain some characteristics of the two modules, and point out how enterprises can better choose their own optical modules in practical applications to improve network efficiency.


In the field of network communication, Gigabit optical modules and 10 Gigabit optical modules are the most common and widely used two types of optical modules. The difference lies in the transmission rate, package, transmission distance, power consumption, transmitted optical power, received optical power, and application scenarios.


The transmission rate of Gigabit optical modules is 1 Gbps, and the transmission rate of 10 Gigabit optical modules is 10 Gbps, which means that the transmission speed of 10 Gigabit optical modules is nearly 10 times that of Gigabit optical modules, which can achieve higher bandwidth.


The second is packaging. Gigabit optical modules use SFP (Small Form-factor Pluggable) packaging, while 10 Gigabit optical modules use SFP+ (Small Form-factor Pluggable Plus) packaging. The physical dimensions of SFP+ and SFP packaging are the same, but the protocol they follow is different.


In terms of transmission distance, Gigabit optical modules can usually achieve longer distance transmission, up to 120km, while 10G optical modules can achieve the longest transmission distance of 80km.


In terms of power consumption, the power consumption of 10 Gigabit optical modules is higher, generally between 1 and 2 watts, while that of Gigabit optical modules is about 1 watt.


Finally, there are application scenarios. In practical applications, gigabit optical modules are capable of daily office work and basic data transmission for most enterprises, while 10-gigabit optical modules are more suitable for enterprises that require high-speed data transmission and low latency. For high-end network users, choosing 10G optical modules for networking can bring better network experience and efficiency.


In general, there are still obvious differences between Gigabit optical modules and 10 Gigabit optical modules. When enterprises choose optical modules, they should make choices according to their actual needs in order to achieve better network efficiency and performance improvement.
