AI Technical Summary

Problems solved by technology

[0004] The disadvantage of this optical connector system is that the resultant force exerted by the spring-loaded substrate housing on the backplane is quite high
This resultant force typically exceeds tens of kilograms, causing the backplane to deform, which can eventually cause damage to components and / or signal traces on the backplane

Embodiment Construction

[0019] figure 1 A schematic diagram of an optical connector system 1 comprising a backplane 2 and a substrate 3 is shown. Via the optical cables 4, 5 and the components 6 on the substrate 3, optical communication can be established. Said optical communication may involve a first interface part 7 and a second interface part 8 to establish an optical interface for optical communication. Furthermore, a first electrical contact 9 and a second electrical contact 10 are provided on the backplane 2 and the substrate 3 respectively to allow transmission of electrical signals. Since alignment is critical to provide a low-loss optical interface, it is more preferred for such an optical connector system 1 that the optical interface is completed before the electrical connection between the first and second electrical contacts 9,10 is established. Because otherwise establishing an electrical connection may disturb the alignment of the optical interface.

Abstract

The invention relates to an optical connector system (1) comprising a backplane (2) and at least one substrate (3) with at least one substrate housing assembly (30), the backplane ( 2) Having at least one backplane housing assembly (20) for establishing the optical interface. The base plate housing assembly (30) is connected to the base plate (3) and includes an additional housing (34) slidably mounted in the Z-direction of the base plate housing assembly (30). Therefore, no residual stress acts on the backplane (2) after the optical interface is established.

Description

technical field [0001] The present invention relates to an optical connector system comprising a backplane and at least one substrate having at least one substrate housing assembly, the backplane having at least one backplane housing assembly for establishing an optical interface. Background technique [0002] Optical connector systems typically include a backplane with multiple system cards or substrates. These substrates typically include optical and electrical connections to establish an optical and electrical interface with corresponding components on the backplane. Often, alignment is critical to provide a low-loss optical interface. Therefore, such optical connector systems often require the optical interface to be completed before the electrical connection is made, which otherwise may interfere with the alignment of the optical interface. [0003] US 2002 / 0106162 discloses an optical fiber connection system comprising a backplane housing assembly and a substrate hou...
