DVS20 – FIBER VIDEO SWITCH

Communication switch project described DVS20 is aimed at guiding the flow of data between different manufacturers video SFP modules.

The main task of capturing the signal switch is in one of the twenty occupied ports, and the conversion of the optical signal into an electrical signal and Dotični brought into the matrix, where it may either automatically or manually via the user-friendly interface SW distribution of the signal or signals to other available ports. Control of the matrix will be implemented through local communication I2C to PIC microcontroller.

1 MCU, designed for internal control and control of other building blocks 2 MUX 40x40; matrix switch 3 SFP interfaces 4 PSU, primarily redundant power to all components in the switch

HOUSING

Housing is a standard 19'' metal casing 1U (44mm). At the front of the switch will be openings for insertion of SFP modules, a cantilever Ethernet connector and a couple of light emitting diodes for the diagnosis operation.

DESCRIPTION The switch for the distribution of information in the area of communication speeds of 50 Mbps -

4.25 Gbps . Provided free slots for the installation of SFP interfaces and 20 . 40 ( CSS40 ) . The slots can be fitted various types of video SFP manufacturers. Exactly where manufacturers

are supported will be discussed below. All General Purpose E / O SFP - eat must be total , that are made according to the standard SFF - 8431 Rev 11.0 and / or MSA regulations. The difference between standard and SFF MSA is generally in that MSA is an association founded by rival companies who are pioneers in this field. At MSA association have agreed on basic questions about SFP modules , namely , type of enclosure , connectors , signals on the connector , types of information to the internal EEPROM .. while the SFF Committee was established to standardize hard drives for notebook computers and other small devices . SFF Committee is basically summed up the MSA standard and adding some of their solutions, particularly for the information that is stored in eepromu .

All manufacturers who produce SFP modules are therefore for guidance and SFF . MSA standards. Since the acquisition of new ideas in the standard can be very expensive, manufacturers have in their sales programs, including SFP has not exactly made according to the standards and manufacturers declare the non- MSA products. That's a lot of SFP 's in the digital video world marked non- MSA . How do you feel the difference between these standards will be described in detail in the following sections .

Switch the external monitor and manage scheduled one Ethernet console port . The user will be available via the console port of the affected easily manage via WEB interface , which will be built into the switch. The switch will also support SMTP clients and a few other features related to the control and management of the E / O - electro- optical transducer

SFF - Committee governing standards and regulations for the SFP communication modules MSA - the association of the first manufacturers of SFP modules , founded with the aim of

standardizing the rules HW and SW basic features.
