Are all MPO connectors APC?

Basic Overview of MPO Connectors
MPO connector is a multi-core connector standard, typically specified by IEC 61754-7. This connector design is used to combine multiple optical fibers into an array, greatly simplifying the routing and management of optical fibers. MPO connectors typically arrange 12 fiber optic cables in a row, but can also support one or more rows of fibers in the same connector, forming configurations with 24, 32, or even higher core counts.
The types of MPO connectors are distinguished based on multiple factors, including the number of cores (number of fiber arrays), male female heads (Male Female), polarity (Key), and polishing type (PC or APC). Among them, the number of cores determines the number of optical fibers that the connector can accommodate, the male and female heads determine the pairing method of the connector, polarity is managed through a key to ensure correct connection, and the polishing type determines the processing method of the fiber end face.
Characteristics of APC connector
The APC connector, also known as the Angled Physical Contact connector, is characterized by a special treatment of the fiber end face to form an 8 ° inclined surface. This design helps to reduce reflection losses during fiber optic connections and improve the transmission efficiency of optical signals. APC connectors are commonly used for single-mode fiber optic communication, especially in high-speed, long-distance fiber optic transmission systems.
The relationship between MPO connector and APC
Although MPO connectors can support multiple polishing types, including PC (Physical Contact) and APC, it does not mean that all MPO connectors are APC. The polishing type of MPO connectors depends on specific application requirements and design choices. In some cases, to reduce reflection loss and improve transmission efficiency, APC polished MPO connectors may be chosen. However, in other cases, PC polished MPO connectors may be more suitable because PC polishing has better interchangeability and compatibility.
Application scenarios of MPO connectors
MPO connectors play an important role in various application scenarios due to their multi-core count and ease of management. These scenarios include but are not limited to:
Enterprise LAN cabling: MPO connectors can simplify fiber optic cabling between buildings or floors, improving the reliability and efficiency of network transmission.
Optical active device interconnection: In optical active devices such as optical amplifiers and switches, MPO connectors are used to interconnect optical links and ensure stable transmission of optical signals.
Wiring within communication base stations: In mobile communication base stations, MPO connectors are used to connect fiber optic links between base station equipment, supporting high-speed data transmission and signal processing.
Wiring inside the distribution box: In the fiber optic distribution box, MPO connectors are used to manage and allocate fiber optic resources, improving the flexibility and scalability of the fiber optic network.
Fiber optic communication system: MPO connectors play an important role in fiber optic communication systems, supporting long-distance and high-speed fiber optic transmission.
Selection of MPO connector and APC connector
When choosing MPO connectors, multiple factors need to be considered, including the number of cores, polishing type, polarity, environmental adaptability, etc. The selection of polishing type should be based on specific application and transmission requirements. If low reflection loss and high transmission efficiency are required, APC polished MPO connectors are a better choice. However, if more emphasis is placed on interchangeability and compatibility, PC polished MPO connectors may be more suitable.
