Product Description
1 Integrated Service Optical Terminal Equipment
One-fiber integrated service optical terminal equipment can achieve 100MB Ethernet data within one single fiber. The four different format data streams transmit in two (one) way. Meanwhile, the common used two wavelength of 1310 and 1550 light input (output) are reserved. It can greatly improve the service efficiency of single fiber.
Technical index
Optical input(output)channel
Insertion loss <1.5dB
Insulation >40 dB(measure with an interval of 20nm)
Work temperature -40-85 degree
ASI interface
With the international standard of DVB-ASI, such as Chinese standard, European standard, CMMB stream and so on. It supports two-way transmission. No stream enter can perhaps destroy the error correction and verification byte of existing data structure.
Ethernet interface
Support IEEE 802.3U Ethernet
Support full duplex or half duplex, and equip with auto negotiation.
RJ45 twisted-pair interface
2 Multi-channel DTMB ASI stream + IP Digital Microwave Transmitting System
The system can transmit N*(3 ASI streams + 1 IP stream). N is the quantity of the digital microwave IDU. Each IDU has 3 interfaces for ASI stream inputting/outputting and 1 IP stream interface. Each IDU supports maximum input rate of 70M. Through splitter/combiner, MK666 IDU RF IN and RF OUT share one antenna feed system, which can make the system update to N*70M easily.
System Features
The system adopts the special transparent transmission mechanism of our company, with DVB-S modulator standard transmission. Without stream processing inserting, it will destroy data structure and bytes. The circuit interfaces are complete self-adaption, which is very important for single frequency network.
It has high sensitivity. Compared with PDH, SDH and IP communication microwave, its demodulator threshold has more 5-8 dB. Therefore, with the same size of antenna diameter and same power allocation, this system will transmit farther and more stable.
Guilin Mingke Communication Equipment Co. Ltd., located in Guilin High-tech Zone Venture Park, it's predecessor was established in 1989. The products such as Front-end Digital Radio System, microwave devices and the band planes microwave tramsceiver have completely proprietary intellectual property rights.
We can provide complete system engineering solutions for users with world-class professional measuring instruments, from HP, Japan Anritsu, micro-companies etc, and a ladder-shaped configuration optimization of engineering and technical forces haveformed already.
The company is applying for ISO quality system authentication, and it's portabletwo-way transmission machines of moving images have already passed military authentication, also the two-way multimedia digital microwave transmission equipments have been exported to Korea and Southeast Asia in batches.
The company always follow "the quality throughout first, theprestige supremely", and we are willing to create the glorious future with fellow colleagues altogether.
