There are many medias to be used for interconnects among network equipment, copper and fiber, copper with its limitation of transmit distance, normally used for intra racks, and optics with longer transmission distance and used for inter-racks or inter-DCs. As for the copper media, there is DACs and ACCs. DACs, it is short for Direct […]
1. What form-factors are used for 800G transceivers? There are two main form-factors for 800G transceivers now, the OSFP and the QSFP-DD: OSFP Form Factor: OSFP is an abbreviation of Octal Small Form-factor Pluggable. This transceiver with Octal (8) electrical lanes, with each lane modulated at 100Gb/s to reach a bandwidth of 800Gb/s. It is […]
AI requires enormous computing capacity, and the operators shall require lots of space for equipment, currently VSFF connector is becoming the idea solution for the AI, but also, people are seeking for new fiber to increase the density also. the following fiber maybe the choice of it. Few Mode Fibre Multicore Fibre Few Mode Fibre […]
The ITU-T G.652 optical fibre standard was born in the year of 1984, 40 years ago. Happy birthday to the bedrock of broadband. During the last few decades, the fiber standard is evolving, we are summarizing it for you. Data Center and Campus G.657.D: The G.652.D nowadays is known as standard single-mode fiber and cable […]
The three most common MPO connector options are MPO-8, MPO-12, MPO-24 and MPO-16. MPO-8 is a legacy standard for the QSFPs, coming out of the transceivers running 40 Gigabit or 100 Gigabits. It is used for both multimode and singlemode transceivers and breakouts, but offers the lowest density option, because you’ll have to have more […]
The TMT ferrule format is based on the proven alignment structure of MT and MT-16 ferrules used in MPO and MPO-16 applications. Engineered for durability, the novel shoulder features ensure precision polishing combined with the mechanical integrity needed for repeated insertion and extraction cycles. In addition to MMC applications, TMT ferrules are ideal for on-board […]
The fiber is fragile and easy to break, the cable jacket is a good measure to protect the fiber been damaged. The cable structure includes buffers, strength members, and jackets. The following articles offer a brief introduction to the cable jacket used inside the data center. LSZH LSZH (low-smoke, zero halogen) jacket is free of […]

There are three core optical interconnects for Artificial intelligence (AI) and machine learning (ML), respectively VCSEL, EML, and CPOs. 1. VCSEL: Vertical-Cavity Surface-Emitting Lasers, it is normally used for short link connection, it are a workhorse for optical AI interconnect technology across the industry. It features low power and low cost, it is ideal for […]
2028. While the 800G and 1.6T pluggable now are mainly based on 16 fiber, in the article, we shall briefly introduce the Base-16 Fiber Cabling System. 1. What is Base-16 Fiber? Base-16 fiber mainly means 16x fiber cores in a tube and can be single or ribbonized. it can be terminated by high-density MPO, MTP […]
