要的角色，光纖介面收發器係透過其内所設之光電轉換模 組，進行電氣訊號與光訊號間的相互轉換，以使各式電子裝 置能透過光纖通訊網路相互連線。一般言，光纖介面收發器 隨著應用環境的不同，已發展出多種封裝形式，包括早期的1 χ9 pin類比式接頭、千兆位元介面轉換器（Gigabit Interface converter ’ 簡稱 GBIC)、小封裝收發器（Small FormFactoi*， 簡稱SFF)、小封裝可插拔收發器（Small F〇rm Factor Pluggable ’簡稱SFP)、四通道小封裝可插拔收發器（Quad Small Form Factor Pluggable ’ 簡稱 QSFP)以及萬兆小封裝 可插拔收發器（10 Gigabit Small Form Factor Pluggable， 簡稱XFP)等’其中GBiC、SFP、QSFP及XFP係屬於可熱插拔 式的封裝，在電子裝置的工作過程中，可依實際需求，抽換 其上之光纖介面收發器，因此，此類光纖介面收發器在實際 應用上，非常具有彈性。另，為了提高這類可支援熱插拔的 光纖介面收發器之產品相容性，相互競爭的廠商間共同制定 了 一套多源協定（Multi-Source Agreement，簡稱 MSA)，以 針對GBIC、SFP、QSFP及XFP之規格進行規範，使這類光纖 介面收發器成為具備國際標準的可互換產品，其所帶來的便 利性不啻成為光纖通訊網路普及化的一大助力。 在MSA規範下’雖然設置於光纖介面收發器之插接頭底 面的電性端子能直接暴露於外’惟’設置於插接頭頂面的電 性端子’卻因為十分接近光纖介面收發器的殼體前端之延伸 邹，而使其受到該延伸部遮蔽，令維修人員無法由收發器的 直接驗其磨損情形。因此，目前在麟光纖介面收發

New description: [New technology field] This creation department has a system domain interface device. The top surface of the plug connector of the fiber interface transceiver is provided with a plurality of electrical terminals, which can directly pass through the two detection holes. The electrical terminals are observed to facilitate the wear of each of the sub-assemblies. ^ [Prior Art] In recent years, due to the increase in communication over long distances and large quantities of materials, the industry has continued to develop more and more communication transmission technologies in response to this urgent market demand, in order to provide a transmission. A faster, more distant, and more stable communication system. With the evolution of time, the transmission medium has been upgraded from the general signal line to the coaxial power supply, and then to the optical fiber communication system. The "viewing and precision of these communications" with the technology _ new with the times, resulting in poor news The speed and distance of the transmission wheel have been greatly increased to unprecedented levels. Because the fiber trajectory makes the job, (4) Wei shouts, the information is transmitted, so the error is not affected by the electromagnetic transmission system for information transmission. The impact of interference, and can avoid the power loss and transmission attenuation of the traditional electrical signal through the process of steel wire transmission. In addition, in recent years, with the continuous decline in the price of related soft and hardware equipment, and network sensitivity With the continuous growth of demand, optical fiber communication has become the most important wired communication system today, and has been widely used in the secret of the United States, the world's various industries have also developed towards the direction of all-fiber communication scales, and (10) Hit the home, _FTTH) as the ultimate goal of network cabling. M424708 plays an extremely important role in the optical fiber communication network according to the 'fiber interface transceiver. The optical interface transceiver converts the electrical signal and the optical signal through the photoelectric conversion module provided therein, so that each Electronic devices can be connected to each other via a fiber optic communication network. In general, optical interface transceivers have evolved into a variety of package formats, including early 1 χ 9 pin analog connectors, Gigabit Interface converters (GBIC), and small package transceivers. Small FormFactoi* (SFF for short), Small F〇rm Factor Pluggable (SFP for short), Quad Small Form Factor Pluggable (QSFP for short) and 10,000 10 Gigabit Small Form Factor Pluggable (XFP), etc. 'GBiC, SFP, QSFP and XFP are hot-swappable packages, which can be used in the operation of electronic devices. Demand, replacement of the fiber interface transceiver on it, therefore, such fiber interface transceiver is very flexible in practical applications. In addition, in order to improve the product compatibility of such hot-swappable fiber-optic interface transceivers, competing vendors have jointly developed a Multi-Source Agreement (MSA) for GBIC and SFP. The specifications of QSFP and XFP are standardized, making such fiber-optic interface transceivers an interchangeable product with international standards, and the convenience brought by it is not only a great help for the popularization of optical fiber communication networks. Under the MSA specification, the electrical terminals disposed on the bottom surface of the plug-in connector of the fiber-optic interface transceiver can be directly exposed to the external 'only' electrical terminals disposed on the top surface of the plug connector, but because they are very close to the housing of the fiber-optic interface transceiver. The extension of the front end is such that it is shielded by the extension, so that the maintenance personnel cannot directly detect the wear and tear of the transceiver. Therefore, at present, the inspection of the fiber optic interface transceivers is carried out by two computers, which are respectively connected to two electronic devices (such as a 1-switch) equipped with a fiber-optic interface transceiver, and by a fiber optic cable. The wires are connected to the optical fiber interface transceivers to form an independent detection system (eg, by the first computer, the first switch, the first optical interface transceiver, the optical fiber, the second optical interface, the second switch, and the Second computer = sequence of independent detection system), 嗣 'Test whether the aforementioned computers can establish a connection? According to the judgment, whether or not the Wei of the optical fiber interface of the independent inspection system is positive or not, there are many shortcomings in these practices. , check, speed, distance and stability were originally the three basic requirements of the communication system and Ik leap forward in various communication technologies. Today's optical fiber communication systems have reached a very high level in terms of transmission speed or distance. At the same time, the complexity and precision of the fiber-optic rail system have also increased. Therefore, how to maintain the domain IT office and recitation is an important issue in the silk industry. First of all, in order to make the fiber-optic communication system transfer well, it is necessary to ensure that all components of the fiber-optic communication system can operate normally, and in the event of failure of any component, it must be able to quickly detect the problem, so that in short-term Secondly, because the optical fiber interface transceiver is not only an indispensable important component in the optical fiber communication system, but also in the _ fiber-optic communication system, it is often equipped with the light age pure hair of the Xuxiang, the material-aged transceiver. After long-term use and multiple plugging and unplugging, it is inevitable that the electrical terminals installed in the plug connector will be short-circuited due to the dragon, thus, the serious operation of the system will be seriously affected. Therefore, in order to save the maintenance personnel (four) the county fiber interface transceiver into the expedition - the time required for maintenance, it is necessary to plan a __ detection method, · M424708 to enable maintenance personnel to check the speed and relatively the same fiber interface The transceiver performs the test 'only' and now many of the treasury laws are unable to meet this basic requirement. Taking the commonly used front-to-face transceivers as an example, the silk interfaces are usually connected to the electronic device (&: switch), and the sub-devices are often placed in an independent 'JL machine' In order to perform maintenance through the conventional detection method, the maintenance personnel must carry at least two computers (such as a notebook computer) into the machine or unplug all the fiber interface transceivers to be repaired, and such After the optical fiber interface "to the place with at least two computers" is fully tested, the optical interface transceivers are brought back to the equipment room, and the transceivers are sent in the slots of the electronic devices. The process is very complicated and inconvenient. In addition, in order to be able to simultaneously detect a large number of optical interface transceivers, each of the electronic devices must withstand the intensive and large-scale insertion and removal of the optical fiber interface transceivers. It is also very easy to cause the slot of the material electronic device (4) the electrical contact to wear rapidly. In addition, when maintenance is performed by the conventional detection method, if the maintenance personnel finds the electronic devices, the normal connection of the method can only be very rough and judged that the optical interface device may be abnormally 'not properly' but cannot be accurately turned off. Is the cause of the failure such that the terminals are worn (four) into scales? In addition, since the electrical terminal is ground and the short-circuited county can check the function of the interface transceiver, it is good or bad, so the maintenance person s finds that the electronic device can be normally connected, and represents the scale terminal of the Weifa device. No wear and tear, therefore, the maintenance personnel can not pass the two-wire test to confirm that the function of the fiber interface transceiver is normal? The credibility of the resulting results is less than ideal. M424708 In summary, the current detection method for optical fiber interface transceivers is not only inconvenient and inconvenient, and the credibility is still unsatisfactory. Therefore, how to improve the structure of the fiber optic transceiver (in accordance with the specifications specified by MSA), simply adjust the structural design of the fiber optic interface transceiver, so as to effectively improve the personnel to the money interface (four) The spears of the maintenance, J), became an important topic for the creation of this creation. [New content] In view of the many problems brought about by the structure of the conventional optical interface transceiver, the creator has long been working hard to study the end of the experiment, and to design the optical interface interface transceiver with the detection hole.

In this way, since the electrical terminals disposed on the bottom surface of the plug connector can be straightened: exposed to the shell, and disposed at the position of the electrical terminal of the mating surface, corresponding to the specification specified by msa The inspection hole provided by the present invention is used by the maintenance personnel when the needle is inspected and repaired. The electrical terminal disposed on the plugged surface can be observed through the detection hole, so that when the maintenance person M wants to confirm each When the electric terminal (when it is placed on the top or bottom of the plug connector) g wear condition, it is only necessary to pull the wire φ transceiver H from the slot, from the outside view: look Easy to complete the test without the aid of any soft and hard tools, so even if it is not a professional maintenance person, the general user can carry out preliminary tests by himself, and observe the wear of each terminal through the test hole. Very convenient. Another object of the present invention is that the two sides of the extension extend downward to form two side walls. The viewer can continue to view the extension from below the viewing section to increase the structural strength of the extension. A further object of the present invention is that the housing is assembled from an upper housing and a lower housing. The receiving m is located between the upper housing and the lower housing, and the extension can be the upper housing.
