Description

Pluggable optical transceiver with heat sink

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical transceiver equipped with a heat dissipation structure, and more particularly, to an optical transceiver in which the heat dissipation structure is connected to the protrusion of the optical transceiver housing to effectively dissipate heat generated inside the optical transceiver. It is about.

Fiber-optic technology is rapidly increasing in use as a means of transporting information that can be easily transmitted over a communications network. In particular, in a situation where the traffic is gradually increasing, the dependence on the optical fiber technology is gradually increasing to transmit more data using a limited line. Networks using fiber optic technology are known as optical communication networks and feature high bandwidth and reliable high speed data transmission.

Optical communication networks use optical transceivers in transmitting information from the transmitting end to the receiving end over the network. In general, such an optical transceiver implements both data signal transmission and reception capability, so that the transmitter converts an incoming electrical signal into an optical signal while the receiver converts an incoming optical signal into an electrical data signal.

More specifically, the optical transceiver is an optical network unit (ONU) and an OLT of a passive optical network (PON) represented by a Giga PON (GPON), an Ethernet PON (EPON), and a Wavelength Division Multiplexing PON (WDMPON). It is installed in (Optical Line Terminal). By using such an optical transceiver, it is possible to bidirectional optical communication that can transmit and receive using a single optical path.

1 illustrates an example of a conventional generally used optical transceiver. As shown, the optical transceiver includes a housing, a latching mechanism mounted at the front end of the housing, an optical subassembly (OSA) module and a driving circuit mounted inside the housing.

The housing of the optical transceiver can be mounted or dismounted by inserting into a cage according to the specification of the housing so that the housing can be inserted and mounted. The cage is mounted in a port of a host device. The housing is a connector corresponding to a portion excluding the insertion portion of the housing rear end inserted into the cage when the housing is mounted in the cage and the insertion portion of the housing protruding outward when the insertion portion is inserted into the cage. It consists of wealth.

The latching member is for fastening the mounting of the housing and the cage, and is mounted at the front end of the connector portion. When the housing is inserted into the cage and the clip of the latching member is fastened, the locking pin of the latching member is caught by the latching jaw located at the lower end of the cage so that the housing is engaged with the cage. Therefore, the optical transceiver has a plug type structure that can be easily mounted or mounted on the cage using the latching member.

As a representative form of the latching member, US Patent No. 6,439,918, invented and patented by Chris Togami, is an SFP optical transceiver in a cage mounted to a port of a host device. A latching member for mounting and hernia is disclosed.

The optical transceiver has a plug type structure because the above structure is easy for experiment or operation and maintenance of equipment.

The OSA module includes an optical transmitter and an optical receiver and is mounted inside the housing. One OSA module may include an optical transmitter or an optical receiver, or may include both the optical transmitter and the optical receiver. The optical transmitter is mainly composed of a laser diode (LD) and may include a photo diode (PD) for a monitor. The light receiving unit is mainly composed of a photodiode. According to the configuration, the position of the laser diode and the photodiode may be varied with each other.

When the OSA module includes only the optical transmitter, it is called TOSA (Transmitter Optical SubAssembly), when it includes only the optical receiver, it is called Receiver Optical SubAssembly (ROSA), and when it includes both, it is also referred to as Bidirectional Optical SubAssembly (BOSA). Therefore, the general optical transceiver is mounted with BOSA or TOSA and ROSA, respectively.

2 is a view showing an example of a conventionally used BOSA. As shown in the figure, an optical transmitter, an optical receiver, and an optical fiber cable are arranged in a T-shape for bidirectional optical transmission and reception, and an optical system including a filter in the center thereof is positioned at a 45 ° angle. do. When the beam is incident to the BOSA or the beam is output from the optical transmitter through the optical fiber, the beam is separated according to the wavelength in the optical system is incident to the optical receiver or transmitted through the optical fiber.

The laser diode of the optical transmitter of the BOSA or the photo diode of the optical receiver of the BOSA may be mounted in a package called a thiocan (TO-can), respectively or together. In addition, a TEC may be built into the thiocan for temperature control of the laser diode. The thermoelectric element absorbs heat from the laser diode and controls the laser diode to operate at an appropriate temperature.

The driving circuit unit is for power supply, control, and modulation of a signal to the OSA, and is generally mounted at a rear end of the OSA.

The pluggable optical transceiver and its cage are determined by various standards so that products of multiple manufacturers can be compatible with each other, thereby unifying their specifications and interface methods. Representative examples of the standard include small form-factor plugable (SFP), SFP +, and XFP. SFP, the most representative standard for pluggable optical transceivers, standardizes the interfacing function to have a housing that is 9.8 mm high and 13.5 mm wide with at least 20 electrical input / output contacts.

The optical transceiver is mounted to the host device, which is typically equipped with a large number of cages for mounting more than a few dozen optical transceivers. In other words, the host apparatus includes a plurality of cages arranged densely in a plurality of rows and columns in order to maximize the number of cages installed per unit area. In each cage of such a host device, optical transceivers such as the above-mentioned SFPs are respectively inserted therein. At this time, the optical transceiver is also densely inserted according to the arrangement of the socket of the host device.

In order to increase the efficiency of the arrangement, the specification of the optical transceiver is gradually becoming smaller. Optical transceivers are the most commonly used Small Form-Factor (SFF) structure from the initial 300-pin structure to the Gigabit Interface Converter (GBIC) structure, and the specifications are getting smaller. In addition to space constraints, the demand for miniaturization of optical transceiver standards is increasing to be mounted in more compact communication equipment.

As optical transceiver specifications become smaller, the configuration inside the optical transceiver housing must be more compact. Therefore, the difficulty of heat dissipation has emerged as the biggest problem of miniaturization of the optical transceiver. In particular, the difficulty of heat dissipation of the laser diode that generates the most heat inside the optical transceiver has been a problem. TECs can be mounted to control the heat, but more effective methods of heat dissipation have been required. Therefore, the present inventors have studied a heat radiation plug type optical transceiver capable of effectively dissipating heat inside the optical transceiver.
