Fiber Optic Adapter are used in fiber optic connection, the typical use is to provide a cable to cable fiber connection. People sometimes also name them to be mating sleeves and hybrid adaptors, mating sleeves means this fiber optic adapter is used to connect the same type fiber optic connectors, while hybrid adaptors are the fiber optic adaptor types used to connect different kinds of fiber optic connectors. YLTelecom`s fiber adapter provide reliable solution for fiber connections, single mode fiber optic adaptors and multimode fiber optic adaptors available on request. We adopt high quality raw materials and make these fiber optic adapters strictly according to international standard, this makes our fiber optic adaptors with high performance.
Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad).
When connecting two multimode fibers, you should always make sure they are the same core diameter (50/125 or 62.5/125). A mismatch here will cause attenuation in one direction (where the larger fiber is transmitting light into the smaller fiber).
Fiber optic adapters are typically connecting cables with similiar connectors (SC to SC, LC to LC, etc.). Some adapters, called "hybrid", accept different types of connectors (ST to SC, LC to SC, etc.). When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.

Subsequently, Gaogong LED reporter interviewed a number of internal and senior executives of GCL Optoelectronics Technology Co., Ltd. on the above rumors, but the group did not receive any substantive response.
On September 18, Gaogong LED reporter received confirmation from Zhangjiagang Development and Reform Commission: The GCL-Zhangjiagang LED project has been officially suspended. At the same time, the internal core technical team has been dissolved. Subsequently, several LED extension companies around Zhangjiagang also confirmed to Gaogong LED that they had “digging†some technicians from GCL.
On September 23, Gaogong LED reporter interviewed the senior leaders of GCL Optoelectronics Technology Holdings Co., Ltd. exclusively. The other party said that the group is now mainly making structural adjustments to slow down the introduction of MOCVD equipment. However, for the complete abolition of the Zhangjiagang LED project, the person said that the group has no official statement.
The reporter then contacted the public relations department of the GCL Group, but as of press time, he did not receive any response.
Big investment coincides with industry investment fever
GCL Optoelectronics Technology Holdings Co., Ltd. is a member of GCL (Group) Holdings Co., Ltd., and is another major investment in the optoelectronics project of GCL Group following the silicon material project.
According to the previously announced plan, GCL will invest 10 billion yuan in 2011 for the construction of sapphire projects and epitaxial film projects, including Suining (320 units, 200 million US dollars) and Xuzhou (640 units, 200 million US dollars). Construction of 960 sapphire crystal growth furnaces, construction of 200 MOCVD epitaxial equipment in Zhangjiagang, Yancheng, Wuzhong and Wujiang. The largest production base for sapphire single crystal substrate will be built in China.
According to the reporter's understanding, the suspension of the Zhangjiagang LED project was only half a year after the construction started at the beginning of the year.
Tang Cheng, president of GCL (Group) Holdings Co., Ltd., said at the groundbreaking ceremony that the first phase of the project will have a total investment of 540 million US dollars and cover an area of ​​200 mu. It plans to introduce 160 sapphire substrate crystal growth furnaces and 100 MOCVD machines. Annual sales amounted to $1 billion.
On March 19, the GCL Xinguang LED project with a total investment of 2 billion US dollars was started in Yancheng Economic and Technological Development Zone. Prior to December 25, 2010, Suzhou GCL Optoelectronics Technology Holdings Co., Ltd. officially signed an LED epitaxial wafer and chip investment project with Yancheng Economic Development Zone. According to the plan, the Yancheng project will be an important base for the integration of LED epitaxial wafers and chip production, manufacturing and R&D. The total planned investment of the project is 2 billion US dollars, and the first phase investment is 650 million US dollars. 
Fiber Optic Adapters FC, SC, ST, LC, MT-RJ, MU, E2000, FC/APC, SC/APC, LC/APC, E2000/APC, Simplex, Duplex, Quad, mating sleeves, hybrid fiber optic adapters, Single mode fiber optic adapters, multimode fiber optic adapters are all available.
Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables. This can cause misalignment of the small singlemode fibers and loss of signal strength (attenuation).
[High-tech LED News] On September 15, Gaogong LED editorial department received an anonymous letter about the suspension of the GCL-Zhangjiagang project. According to the letter, the GCL-Zhangjiagang LED epitaxial chip project will stop construction and switch to solar photovoltaic projects.
GCL Optoelectronics Technology Holdings Co., Ltd. is a member of GCL (Group) Holdings Co., Ltd., and is another major investment in the optoelectronics project of GCL Group following the silicon material project. The company continues to make "energy saving, environmental protection, green energy" as its mission, and is committed to the development and manufacture of LED chips that are more environmentally friendly, energy-saving and green than traditional light sources.
The company is expected to invest 10 billion yuan in the construction of sapphire projects and epitaxial film projects in 2011. Among them, 960 sapphire crystal growth furnaces will be built in Suining (320 units, 200 million US dollars) and Xuzhou (640 units, 200 million US dollars). 200 MOCVD epitaxial equipment will be built in Zhangjiagang, Yancheng, Wuzhong and Wujiang.
