Abstract
The utility module is suitable for the field of communication and provides a testing system for an optical module. The testing system comprises a host computer and an optical terminal. The optical terminal comprises a CPU and an optical module to be tested. The CPU is connected with the optical module through a communication interface. The host computer and the CPU of the optical terminal have network interfaces of the same protocol. The host computer and the optical terminal are connected through the network interfaces. The CPU converts a test command sent by the host computer into a test command distinguishable by the optical module in the optical terminal. The testing system is very general, easy to use and reliable. Apart from the optical terminal which needs to be designed, no hardware system requires to be designed, so that the cost is lowered and the topology is simplified. The testing system is suitable for testing optical modules packaged on equipment and optical modules not packaged on equipment.

Yet USB turns the technology of I2C in described test macro, only limit to above-mentioned test fixture and be not encapsulated into the optical module on equipment, therefore do not possess versatility and easy design.In addition, the producer for producing optical terminus, design described test fixture, labor intensive, material resources and time in addition.
Utility model content
The purpose of this utility model is to provide a kind of test macro of optical module, is intended to solve prior art and does not possess versatility and easy design, for the producer that produces optical terminus, other design test frock, the problem of labor intensive, material resources and time.
The utility model is to realize like this, a kind of test macro of optical module is provided, described system comprises: computer host computer and optical terminus, optical terminus comprises CPU and optical module to be tested, CPU is connected with optical module by communication interface, the CPU of computer host computer and optical terminus has the network interface of same protocol, between computer host computer and optical terminus, by network interface, connects, and the test command that described CPU sends computer host computer converts the discernible test command of optical module in optical terminus to.
Further, described communication interface is I2C interface, and described optical module is connected with described communication interface by I2C bus.
Further, described network interface is Ethernet interface.
Further, described computer host computer is the computer host computer based on Ethernet agreement.
Further, described optical terminus is 10G EPON optical terminus, EPON optical terminus and GPON optical terminus.
In the utility model, due to the network interface all possessing by computer host computer and optical terminus, CPU in optical terminus is received after the test command that computer host computer sends, convert test command to the discernible test command of optical module in optical terminus, and the communication interface of the CPU in optical terminus is sent to optical module, thereby reach the object by computer PC control and alignment light module.Therefore very general, easy-to-use and reliable; Except the optical terminus that design must design, without designing again other hardware systems, reduced cost, simplified topology; The utility model is applicable to being encapsulated into the optical module on equipment and not being encapsulated into the test of the optical module on equipment.
Accompanying drawing explanation
Fig. 1 is the functional block diagram of the test macro of the optical module that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
