Most of the optical modules are used in the backbone network of the optical fiber network, and the optical transceiver is simply a device to extend the network cable. What is the difference between optical modules and optical transceivers? 1. Optical modules are accessories, generally only used i...

As the two main members of optical network access, EPON and GPON each have their own merits, compete with each other, complement each other, and learn from each other. The following will compare them in various aspects. Rate EPON provides fixed uplink and downlink 1.25 Gbps, adopts 8b/10b line c...

1.1 Passive optical splitter Passive optical splitter is an important component of PON network. The function of the passive optical splitter is to divide the optical power of one input optical signal into multiple outputs. Typically, the splitter achieves light splitting from 1:2 to 1:32 or even ...

Comparison of five PON-based FTTX access The current high-bandwidth access networking method is mainly based on PON-based FTTX access. The main aspects and assumptions involved in the cost analysis are as follows: ●Equipment cost of the access section (including various access equipment and lines...

What is GPON? GPON (Gigabit-Capable PON) technology is the latest generation of broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard ...

There are many signal lights on the fiber optic modem, and we can judge whether the equipment and the network are faulty through the indicator light. Here are some common optical modem indicators and their meanings, please see the detailed introduction below. 1. In order to facilitate the locatio...
