  • Q Why should I trust YXFiber compatible transceivers?

    A Besides the price advantage, we have compared to branded transceivers, YXFiber compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out.

  • Q What kinds of customized choices are offered in YXFiber?

    A As for customized transceivers, YXFiber offers regular custom choices such as compatibility, transmission distance, operating temperature, label pattern, label colors and etc. What's more, YXFiber welcomes any inquiry for customized products and solutions for all need and specifications.

  • Q Differences Between Single Mode, Duplex, and Half Duplex Optical Modules

    A

    In the realm of optical communication, terms like simplex, duplex, half duplex, as well as single-core, dual-core, single-fiber, and dual-fiber configurations are frequently encountered. But what exactly are their connections and differences?

    Let's begin by distinguishing between single-core vs. dual-core and single-fiber vs. dual-fiber optical modules. In the context of optical modules, these terms essentially denote the same functionalities but differ in nomenclature. Single-core and single-fiber optical modules both refer to Bi-Directional (BIDI) modules capable of bidirectional transmission over a single fiber, whereas dual-core and dual-fiber modules are capable of bidirectional communication over two fibers.

    What is simplex?

    Simplex refers to unidirectional data transmission, where communication occurs in only one direction. Examples include printers, broadcasting stations, and monitors, which receive signals or commands without transmitting any.

    What is half duplex?

    Half duplex supports bidirectional transmission but not simultaneously. At any given moment, one end can either send or receive data, but not both simultaneously.

    What is full duplex?

    Full duplex allows simultaneous bidirectional transmission, combining two simplex channels where both sending and receiving devices can operate independently.

    Within optical modules, half duplex corresponds to BIDI modules, utilizing a single channel for both transmission and reception. However, only one direction of data transmission can occur at any given time, with reception commencing after the completion of data transmission.

    Full duplex corresponds to standard dual-fiber bidirectional optical modules, employing two separate channels for transmission and reception, enabling simultaneous bidirectional data transfer within the same timeframe.

  • Q How to clean the interface of an optical module if it is dirty?

    A
    Before cleaning optical fiber connectors, use professional cleaning tools. Generally, the tools used to clean optical fiber connectors include optical fiber cleaning paper, alcohol, and cotton swabs.
     
    Optical fiber cleaning paper is a special paper that can effectively remove dirt and impurities from optical fiber joints. Before cleaning the optical fiber connector, you need to blow the optical fiber head, and then use the optical fiber cleaning paper to gently wipe the optical fiber head until the optical fiber paper is no longer dirt.

  • Q The optical fiber is disconnected. Is the module damaged?

    A The connection failure of the optical fiber network module may be caused by loose cables or dirty ports. At this time, you can check that the connection line is crooked and firmly connected, if loose, update and plug once. Can be used for cleaning hammer + pick up alcohol or special cleaning fluid clean stains connection port: to ensure that the signal can be transferred smoothly.

  • Q Why is the optical module indicator off?

    A
    1. The optical module is faulty
    When the optical module is faulty, the indicator may not turn on. In this case, you can replace the optical module with a new one. If multiple optical modules exist, you can locate the faulty optical module one by one.
    2. The optical module is damaged
    Optical module damage is also one of the reasons why the indicator is not on. This may be caused by the optical module suffering from excessive voltage shock or overcurrent and other problems, resulting in its normal work. The solution includes replacing the optical module or repairing the damaged optical module.
    3. The optical module is improperly connected
    If the optical module is improperly connected, its indicator will be off. This may be because the interface is not tight enough or loose, or there are problems such as dirt or corrosion on the interface. The solution includes checking that the connection is strong and cleaning the connection so that it can be connected properly.
    4. The optical module driver is faulty
    If the optical module driver is faulty, the indicator is off. If the optical module driver is damaged or faulty, the optical module cannot work properly and cannot output signals. At this point, the drive can be replaced or repaired.
