When it comes to passive optical networks (PONs), there are a few options users can consider for voice and data cabling. These systems use fiber optic technology to allow individual access to networks. The goal of a PON is to lessen the amount of fiber optic line used, making network cabling simpler and more efficient.
Compared to other types of network cabling, PON, using fiber optic technology, offers high bandwidth rates. Many view it as an improvement over traditional choices for voice and data cabling, like DSL. In choosing PON, users can opt for GPON or EPON to meet their network cabling needs.
Gigabit PON, or GPON, is used fairly often for fiber optic network cabling and is one of the most popular systems in America. GPON has varying components when it comes to voice and data cabling. It uses Asynchronous Transfer Mode (ATM) and a proprietary encapsulation for voice, and ethernet for data.
Ethernet PON, or EPON, is the fiber optic technology primarily used in Asia and Europe. In terms of voice and data cabling, EPON uses one single Layer 2 network to transmit data, voice, and video, lessening the protocol encapsulation needed when compared to GPON.
Many of the aspects of these two types of network cabling are similar, but each operates in a different way.
Implementing GPON fiber optic network cabling can be more complex than installing EPON. This is because it requires virtual circuits for every type of service sent from the network provider to users.
EPON voice and data cabling works with ethernet devices which are very commonplace in homes and businesses. Because of this, it is often easier and more cost effective to set up this type of network cabling.
The cost for EPON equipment is similar to that of traditional broadband technology, while GPON voice and data cabling equipment must account for ATM making it more expensive for users.
When it comes to security, GPON fiber optic technology may be less desirable for your sensitive network cabling needs. It only provides downstream encryption, while EPON voice and data cabling offers encryption downstream and upstream.
When considering voice and data cabling needs, consider that GPON may provide a faster link speed than EPON, depending on how it is operated.
Both EPON and GPON have advantages and disadvantages — a fiber optic cabling company can help you determine which system will best meet your needs.
