High-speed transceiver parallel optics MT subassembly

With the growth of global data volume, parallel optical technology is an important technical for the expansion of current data centers, and the optical transmission rate has continuously evolved from 10Gbps, 40Gbps, 100Gbps to 200Gbps, 400Gbps, and even 600Gbps, 800Gbps. At this year's OFC conference, a number of Chinese suppliers have successively demonstrated 800G rate optical modules, which means that 800G will enter a new era.

What is parallel optics? Parallel optical technology is a special optical communication technology that transmits and receives signals at both ends of the link. Parallel optical transceiver modules are usually used to achieve high-speed signal transmission at both ends. Parallel optical technology is a cost-effective solution for 4×50G, 8×50Gbps transmission.

In parallel optical signal transmission, the parallel optical modules at both ends of the link contain multiple transmitters and receivers. Multiple optical fibers are used to transmit and receive signals. The data rate of multiple-channels parallel transmission can support 40G to 100G per second. As shown in the figure, 8-bit data is simultaneously transmitted through parallel lines, so that the data transmission speed is greatly improved. Multimode parallel technology is mostly used for short-distance transmission of 100G and below.

Parallel optical modules rely more on high integration and small packaging to generate less heat than multiple discrete devices. MT (MPO) ferrules and optical subassemblies are one of the key components supporting parallel optical interconnects, which are used to connect internal optical lenses and external optical interfaces, and can be integrated into optical module boards. The small size and multi-channel of the MT ferrule makes it easy to use as an external optical interface in the parallel transmission.

Relying on high-density parallel optics design and manufacturing capabilities, as well as high-precision mold manufacturing and measurement technology capabilities, HYC now has the mass production capacity of high-speed transceiver optical subassemblies.

MT-Jumper
The ferrules of MT-jumper are available in 0° and 8° polishing angles. The length tolerance can be customized, and the minimum can meet ±0.15mm.

MT-2×Mini MT
Due to the compact internal structure of some optical modules, the traditional MT ferrule is bulky and may not be able to be inserted into the transceiver. Mini MT ferrules are the right devices to use in this small space connection, which are half the size of traditional MT ferrules.

MT-FA
MT-FA is a short fiber jumper composed of MT and fiber array. The end face angle of FA can be customized and it requires high precision. It is widely used in 100G PSM4 to connect to the external port.
