The VFC-2000 series VFC adopts all-digital uncompressed technique of digital video and international advanced technique of digital video and ultrahigh speed optical fiber transmission so that it can ensure the distortionless and high quality transmission video frequency and the signals of audio frequency, data, Ethernet, phone etc on single core or twin-core. It can economize the user's set capitalized cost greatly, and has raised the optical cable utilization ratio.

The VFC-4000 series VFC adopts all-digital uncompressed technique of digital video and international advanced technique of digital video and ultrahigh speed optical fiber transmission so that it can ensure the distortionless and high quality transmission video frequency and the signals of audio frequency, data, Ethernet, phone etc on single core or twin-core. It can economize the user's set capitalized cost greatly, and has raised the optical cable utilization ratio.

The HTD non-condensing ring VFC use the ring net of non-compression technique of numeral and the WDM's technology type numeral fiber equipment, and forming one / by way of the one rush pith two rush piths / optical fibers two fine from more the ring net or chain nets, simultaneous transmission multipath video frequency and data signal；And control can be realized to the preceding end video camera. Increasing CWDM's technology is realized: Form single fiber/multi-fiber spontaneous cure ring net or chain net by way of single/double core fiber. The HTD ring VFC video quality attainability is arrived broadcast standard，support RS-422 and RS-485(2/4) ,etc data communication format.

The HTD cascade digital video fiber transmitter and receiver adopts international advanced technique of digital video and ultrahigh speed optical fiber transmission so that it can ensure the distortionless and high quality transmission of Ethernet on single core or twin-core. The HTD cascade digital VFC uses the complete digital and not-compression technique，the video frequency effect of high quality can satisfy the requirement of user，each product has passed through strict and integrated quality test process including technique capability test and aging test before sale. We also can customize products to meet special requirement of different users. This equipment weave net method is nimble, can realize stelliform and cascade etc network topological structure, its single wavelength fully can realize 8 - 16 cascade connection methods of node, each other combine with CWDM technology, and can realize the cascade connection transfer of even more
