Description
Technical Field
The present invention relates to a small-sized pluggable transceiver, and more particularly, to a small-sized pluggable transceiver with a function of supporting copper cable transmission.
Background
As critical network systems (e.g., servers, central control systems, etc.) are increasingly popular in the field of network devices, signal transmission arrangements for network systems are becoming more and more important. In particular, optical fiber transmission is utilized, and light transmission in the fibers based on the principle of total internal reflection can be utilized, so that the optical fiber transmission has the advantage of high transmission speed. Also for this reason, transceiver devices for optical fiber transmission are derived. Among them, the Small form-factor (SFP) is a transmission application of Small form-factor (factor pluggable transceiver) and is of great interest. The small-package hot-plug transceiver is a small hot-plug optical transceiver, is used for optical communication application in telecommunication and data communication, and is mainly applied to a motherboard of a switch, a router and other devices and optical fiber transmission of an optical fiber or UTP cable.
However, small-package pluggable transceivers are generally not suitable for copper cables because the transmission rate of copper cables (typically below 10 Gbps) is much lower than the transmission rate of fiber optic cables (typically above 10 Gbps), and cannot be applied to small-package pluggable transceivers with high transmission rates. However, copper cables generally have the advantage of being structurally stable and reliable, and inexpensive. If the cable is used in the situation that the transmission rate is not required to be too high, the cost performance of using the copper cable as the signal transmission is high. However, the small-package pluggable transceiver cannot be compatible with the copper cable, so that the small-package pluggable transceiver often needs to be replaced by other transceiver equipment for connection by using the copper cable, which results in poor compatibility.
Therefore, how to design a small-package pluggable transceiver with a function of supporting copper cable transmission, so that the small-package pluggable transceiver can be compatible with a copper cable type signal source is a big subject to be studied by the inventor.

Detailed Description
The structural and operational principles of the present invention are described in detail below with reference to the accompanying drawings:
fig. 1 is a schematic view showing the appearance of a small-package pluggable transceiver with supporting copper cable transmission function according to the present invention. The Small form-factor pluggable transceiver 100 (SFP) is configured to couple the cable connector 200 with the network device 300, and the cable connector 200 is coupled to the cable 200A. The small form factor pluggable transceiver 100 is primarily used for optical communication applications in telecommunications and data communications and is configured to bi-directionally transceive data/signals to and from the cable 200A and the network device 300. The network device may be a network communication device such as a router, a switch, an optical transceiver, or an optical transceiver, and the cable 200A may be a copper cable such as a copper cable or a twisted pair cable. The twisted pair cable may be, for example but not limited to, a general network cable and the copper cable may be, for example but not limited to, an active or passive copper cable (DirectAttach Cable; DAC).
Further, the small-package pluggable transceiver 100 is mainly an optical transceiver, and the prior art generally uses optical fiber cable coupling to make the small-package pluggable transceiver 100 capable of bi-directional transmission of optical signals of the optical fiber cable. However, the small-package pluggable transceiver 100 is generally not suitable for copper cables because the transmission rate of copper cables (typically below 10 Gbps) is much lower than the transmission rate of fiber optic cables (typically above 10 Gbps), and cannot be applied to small-package pluggable transceivers 100 with high transmission rates. When the small-package pluggable transceiver 100 is docked with the optical fiber cable, the small-package pluggable transceiver 100 can recognize the docked cable 200A as the optical fiber cable, and accordingly operates in a normal state to perform data/signal transceiving normally. On the contrary, when the small-sized pluggable transceiver 100 is docked with the copper cable, the pluggable transceiver 100 cannot identify the docked cable 200A, and accordingly, the data/signal transmission and reception cannot be performed normally due to the abnormal operation.
Fig. 2 is a schematic structural diagram of a small-package pluggable transceiver with supporting copper cable transmission function according to the present invention, and fig. 1 is also shown. The small-package pluggable transceiver 100 includes a first connection port 1, a conversion unit 2, a transceiver unit 3, and a second connection port 4, and the first connection port 1 is used for docking the cable connector 200 and coupling the cable 200A to receive and transmit a signal source Ss provided by the cable connector 200. The first connection port may be an RJ-45, SC, ST, MT-RJ or LC connection port, depending on the type of connector of the cable connector 200. The conversion unit 2 is coupled to the first connection port 1, and the conversion unit 2 includes a bandwidth indication pin 2A (e.g., without limitation, led_link100, led_link1000, etc.). The conversion unit 2 is a chip of a physical layer (Port Physical Layer; PHY, which may be referred to as a port physical layer) and is configured to convert the signal source Ss into an ethernet frame Fe (frame, or data frame of an ethernet network). The conversion unit 2 may send and receive ethernet frames Fe and the bandwidth indication pin 2A is arranged to indicate the rate of the signal source Ss (i.e. to provide a rate signal Si corresponding to the transmission rate) when the matching with the cable 200A is successful. That is, when the small form factor pluggable transceiver 100 is mated using a fiber optic cable, the small form factor pluggable transceiver 100 successfully mates with the cable 200A, and the bandwidth indicator pin 2A indicates the rate of the signal source Ss (e.g., without limitation, 15Gbps or 20 Gbps). Conversely, when the copper cable is used to dock the small-package pluggable transceiver 100, the small-package pluggable transceiver 100 is not properly matched with the cable 200A, and the bandwidth indication pin 2A cannot indicate the rate of the signal source Ss and is low.
The transceiver unit 3 is coupled to the converting unit 2, and the transceiver unit 3 includes a detection pin 3A (LOS). The transceiver unit 3 is a transceiver chip of the small-package pluggable transceiver 100, which is mainly applied to a network physical layer transceiver chip for optical fiber transceiver, and is used for bi-directionally transmitting the ethernet frame Fe to the conversion unit 2 and the network device 300. The detection pin 3A is coupled to the bandwidth indication pin 2A to receive the indication sent by the bandwidth indication pin 2A. Specifically, when the bandwidth indication pin 2A indicates that the rate of the signal source Ss is an effective rate (i.e., the rate is higher than 10 Gbps), the detection pin 3A adjusts the level of the self pin to a first level (for example, but not limited to, a low level). Conversely, when the bandwidth indicating pin 2A indicates that the rate of the signal source Ss is an inactive rate (i.e., the small-package pluggable transceiver 100 is not properly matched with the cable 200A such that the bandwidth indicating pin 2A is at a low level), the detection pin 3A adjusts the level of the self-pin to a second level (e.g., without limitation, to be at a high level). The second connection port 4 is coupled to the receiving and transmitting unit 3 and is used for interfacing the network device 300, so that the receiving and transmitting unit 3 and the network device 300 bidirectionally transmit the ethernet frame Fe.
When the detection pin 3A adjusts the level of the self pin to the first level, the transceiver unit 3 operates in a normal state to perform data/signal transmission and reception normally. On the contrary, when the detection pin 3A adjusts the level of the self pin to the second level, the transceiver unit 3 operates in an abnormal state and cannot normally transmit and receive data/signals. Wherein, the first level of the detection pin 3A is generally smaller than 0.8V, and the second level is generally larger than 2.4V.
The main purpose and effect of the present invention is that the detection pin 3A is coupled to the ground GND. When the small-package pluggable transceiver 100 is docked using a copper cable, the bandwidth indication pin 2A indicates that the rate is an inactive rate based on the signal source Ss being a copper cable type signal source (whose rate is typically below 10 Gbps), and the detection pin 3A provides a first level based on the inactive rate (i.e., should otherwise be adjusted high, but is forced low because of being grounded) due to being grounded by the resistor R. Therefore, although the transceiver unit 3 is a PHY transceiver chip (network physical layer transceiver chip), the detection pin 3A is coupled to the ground GND, so that the network physical layer transceiver chip is compatible with the copper cable type signal source.
Thus, the small-sized pluggable transceiver 100, which was not suitable for copper cables, is provided with the function of supporting copper cable transmission (the function of optical communication application by using optical fiber cables is still provided). On the other hand, the copper cable has the advantages of difficult fracture, firm structure and relatively low price compared with the optical fiber cable, so that the invention can achieve the effects of reducing the configuration cost of the whole network system and improving the reliability of the system compared with the traditional packaging pluggable transceiver. It should be noted that, in an embodiment of the present invention, the small-package pluggable transceiver 100 may further include a resistor R, and the resistor R is coupled between the detection pin 3A and the ground GND to limit the current from the detection pin 3A to the ground GND, so as to avoid the chip failure caused by exceeding the current tolerance of the pin.
Please refer to fig. 3A for a schematic configuration of a first embodiment of the small-package pluggable transceiver of the present invention, and fig. 3B for a schematic configuration of a second embodiment of the small-package pluggable transceiver of the present invention, in combination with fig. 1-2. In fig. 3A, the small-package pluggable transceiver 100 is configured to be disposed in the network device 300, so as to modularly design the small-package pluggable transceiver 100 and the network device 300, and a user only needs to plug the network device 300 with the cable 200A. In fig. 3B, the small form factor pluggable transceiver 100 is configured to be disposed outside the network device 300, and a user can adjust the configuration of the small form factor pluggable transceiver 100 and the cable 200A based on the requirements of the network device 300.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
