Conventionally, these optical components are discrete (discrete). ), But an optical transceiver in which an optical transmission module and an optical reception module are integrated has come to be adopted, which greatly contributes to miniaturization and cost reduction.

An optical transceiver incorporated in a host device that performs optical communication is not fixedly installed inside the host device, but is used by providing an optical transceiver entrance called a window in the host device and inserting the optical transceiver into this window. ing. As a result, the optical transceiver can be appropriately replaced with respect to various communication device specifications, optical transceiver failures, and the like.

An optical transceiver contains optical elements and electronic circuits necessary for optical transmission / reception in a substantially rectangular optical transceiver body, and an electrical connection plug (connection terminal, receiving side) at one end of the optical transceiver body electronic board, an electronic board The other end has a TOSA portion (laser diode) and a ROSA portion (photodiode) for transmission and reception, and has a receptacle member connected thereto.

A single-sided opening container called a cage is provided in the host device window to accommodate the optical transceiver inserted from the window, and a plug for electrical connection (connection terminal, receiving side) is provided at the back of the cage. If the optical transceiver is inserted into the cage through the window, the connection terminals are electrically connected to each other so that the host device and the optical transceiver can transfer information to each other.

About the stub surface cleaning tool in the receptacle of the optical transceiver produced in Examples 1-4 and Comparative Examples 1-4, each dust removal property was evaluated.

(Dust removal test)
The optical transceiver used for the evaluation was an XFP transceiver TRF5001EN for LC connector (manufactured by Japan Opnext Co., Ltd., receptacle size 4.61 mm × 4.61 mm).
First, dust, dust or the like was attached to the surface of the optical transceiver stub in advance using a cotton swab or the like, and the number was counted. Optical connector end face inspection device FPD-SD01 (manufactured by NTT Advanced Technology Co., Ltd.) is used for observing the state of dust, dust, etc., and automatic determination software FiberCheck 2 attached to the end surface inspection device is used for counting the number of dust, dust, etc. did.
The test method is that the cleaning tool pseudo plug portion is attached to the receptacle of the optical transceiver so that the abutment surface of the adhesive portion or the nonwoven fabric in the pseudo ferrule portion of the optical transceiver receptacle stub surface cleaning tool contacts the stub surface of the optical transceiver receptacle. The number of cleaning steps per stub surface cleaning tool in the receptacle of the optical transceiver is the state where the process of removing the contact surface from the stub surface in the receptacle of the optical transceiver by fitting and sliding is repeated 10 times. . After completion of the cleaning process, the number of dust, dust, etc. on the surface of the stub in the receptacle of the optical transceiver was counted, and the reduction rate (percentage) from the dust, dust, etc. attached to the initial stage was taken as the dust removal performance. The reduction rate was 90% or more, and there was no practical problem.

Subsequently, the foreign substance adhesion was evaluated for the stub surface cleaning tool in the receptacle of the optical transceiver manufactured in Examples 1 to 4 and Comparative Examples 1 to 4, respectively. The optical transceiver used for the evaluation, the equipment used for observation of the state of dust, dust, etc., and the equipment used for counting the number of dust, dust, etc. were used as they were during the dust removal test.

(Foreign matter adhesion test)
Using the optical transceiver receptacle stub surface cleaning tool fabricated in Examples 1-4 and Comparative Examples 1-4 on the optical transceiver receptacle stub surface confirmed to be free of dust, dust, etc., during the dust removal performance test The same cleaning process as the implemented process was performed, and the presence or absence of foreign matter including dust / dust was confirmed. When no foreign matter was found to be attached, there was no practical problem. When foreign matter was found to be attached, there was a practical problem.

Subsequently, the antistatic property was evaluated by measuring the surface resistivity of each of the in-receptacle stub surface cleaning tools of the optical transceivers manufactured in Examples 1-4 and Comparative Examples 1-4.

(Antistatic test)
As a surface resistivity measuring apparatus used for the evaluation, a superinsulator SM-8220 and a plate sample electrode SME-8310 (manufactured by Hioki Electric Co., Ltd.) were used. The surface resistivity was measured according to ASTM D257 Standard Test Methods for Dc Resistance of Conducting Materials (applied voltage 500 V, temperature 23 ° C., humidity 50%).
In the stub surface cleaning tool in the receptacle of the optical transceiver, if the surface resistivity of the cleaning tool portion excluding the adhesive part and the adhesive part is less than 1 × 10 ¹¹ Ω / sq, the antistatic property is assumed and there is no practical problem. If it was × 10 ¹¹ Ω / sq or more, there was no antistatic property and there was a problem in practical use.

The evaluation results regarding the dust removal property, foreign matter adhesion property and antistatic property test are shown in Table 3 below. Regarding the foreign matter adhesion test and the antistatic property test, those having no problem in practice were represented by ○, and those having a problem in practice were represented by ×.

(Evaluation results)
In Examples 1 to 4, excellent results were obtained with respect to dust removal, foreign matter adhesion, and antistatic properties.
On the other hand, in Comparative Example 1, although there was no problem in dust removal property and antistatic property, a problem in foreign matter adhesion was confirmed. This is because the cleaning tool does not have a pseudo plug part when repeating the contact and detachment of the cleaning tool adhesive part contact surface, the structure cannot stably contact the cleaning tool adhesive part contact surface, It is thought that the cleaning tool adhesive part adhesive was damaged by the twisting of the cleaning tool.
In Comparative Example 2, although there was no problem with dust removal and foreign matter adhesion, there was a problem with antistatic properties because no antistatic agent was added to the cleaning tool.
In Comparative Example 3, there is no problem in the antistatic property, but the resin of the pseudo ferrule part of the cleaning tool is a polypropylene resin when the cleaning tool adhesive part contact surface comes into contact with the stub surface in the receptacle of the optical transceiver. Because it is molded, the affinity of the cleaning tool adhesive part with the acrylic adhesive is not good, and all the cleaning tool adhesive part adhesive is transferred to the stub surface in the receptacle of the optical transceiver from the initial cleaning process stage. As a result, problems have arisen in dust removal and foreign matter adhesion.
In Comparative Example 4, since the antistatic nonwoven fabric was used instead of the cleaning tool adhesive portion, there was no problem in the antistatic property, but the lint generated from the nonwoven fabric was generated with respect to dust removal and foreign matter adhesion. It became a problem and a problem.
From the above results, it was confirmed that the stub surface cleaning tool in the receptacle of the optical transceiver of the present invention has excellent performance with respect to dust removal, foreign matter adhesion, and antistatic properties.
