Note 1: “x”=space, Standard: 0℃~+70℃; “x”=I, Industrial: -40℃~+85℃.

Note 2: “xx” is transmitter optical output close or open and Optical receiver Input indicated.

Transmitter optional as below:

B= Tx-BEN ( 0- close the laser 1- open the laser);D=Tx-DIS (0-open the laser 1-close the laser)

Receiver optional as below:

S=RX-SD （0-signal loss 1-signal valid);L=Rx-LOS (0- signal valid 1-signal loss)

So complete Part No. is GACF-1303-02DS

Note 3: “MMF” stands for 50/125µm MMF；“SMF” stands for 9/125µm SMF

R&D laboratory

Gigac has introduced numerous precision testing equipment, such as Ixia XGS12, Ixia WaveTest 93, Anritsu, Fujikura, Fluke, JDSU, Agilent, EXFO, DATA-PIXEL, etc., for product development testing and validation.At present, there are over 100 professional engineers, of which 50% are senior engineers. Through standardized testing processes and in line with international professional testing standards, we provide testing in various aspects such as product appearance, performance, compatibility, and solution scenarios to meet the diverse testing needs of global customers.

Numerous research and development achievements

Gigac adopts a research and development model that combines independent research and joint development, and has achieved outstanding results in industrial design and product software and hardware research and development.As data centers continue to expand and grow, a well planned cabling infrastructure is crucial. Without flexible cabling plans that can easily adapt to common moves, additions, and changes, your network growth will be limited. The Gigac series high-density data center cabling solutions can simplify deployment, enabling up to 144 LC fibers in 1U, and enabling flexible expansion and rapid upgrades with increasing business traffic demands.

Gigac Test Center

Gain a comprehensive understanding of Gigac's optical modules, fiber optic jumpers, and enterprise network testing center. We have a comprehensive testing plan, professional testing equipment, and standard testing procedures.
