The growing demand for bandwidth in the Cloud, Artificial Intelligence, Machine Learning, etc, and future hyper-scale data centers drive the demand for 800GE Optics. Market researchers consider that 400G will hold sway until 2023 and that 800G will come into its own as of 2025. This article is introducing the options of the 800G transceivers. […]
Distributed fiber optic sensing is using multiple distributed fiber optic sensor along with the fiber, and detect the changes in temperatures, strain, acoustics, etc. of the environment. Following with Several infrastructure monitoring applications. Detection of ground movement along a pipeline Detection of mechanical deformation of the pipeline Detection and location of any leakage along a […]
VSFF Connector is the next-generation connector for fiber optics, especially the high-density data center cabling network. It is short for a very small form factor connector, compared with traditional SFF connector (Small Form Factor connector) like Duplex LC and MTRJ, etc, it is much more compact. It utilizes a reduced ferrule pitch to enable a […]
Cabling is important in the data center/central office. there are two main media used inside the stat center, copper and fiber, the following tables are information on copper and fiber used inside the data center, selecting the right media for the current application and future upgrade is important. Copper Category ISO Channel Class Maximum Bandwidth […]
D’SDSFP Dual Small Form-Factor Pluggable DSFP MSA is developing a SFP+/SFP28 compatible form factor for 5G Mobile applications DSFP has two TX/RX high speed pin pairs, instead of one TX/RX pin pair in SFP+/SFP28 DSFP is mechanically the same as SFP+/SFP28 modules DSFP host ports accept SFP+/SFP28 modules Some SFP+/SFP28 hardware control and alarm pins […]
There are lots of QSFP-DD variants in the market, they are able to be classified by the suffixes, the following text briefly introduces those suffixes. SR8: SR is an abbreviation of Short Range, it refers to transmitting over multimode fiber up to 100m, while 8 means 8x optical channel pairs (8x Tx and 8x Rx), […]
The IEEE P802.3db 100 Gb/s, 200 Gb/s, and 400 Gb/s Short Reach Fiber Task Force has completed its last draft. The standard, which covers high-speed interconnect requirements over 50 and 100 m of multimode fiber. This standard will cover VCSEL based duplex 100G-per-lane transmission over short reach (SR) distances of up to 100 m and […]
Copper is still playing an important role in nowadays data centers, however, data center evolution is moving faster than in the past years, and lane speed quickly increasing in the large data center. there are lots of articles with the main topic of comparison between copper and fiber, thus there are lots of obstacles to […]
Introduction 100G Single Lambda transceivers were defined by 100G Lambda MSA (100G Lambda Multi-Source Agreement). The MSA 100G MSA uses 100G PAM4 optical signaling and encoding it is able to use 100Gb/s per channel to transmit from 2m up to 40KM via single-mode fiber. Advantages The traditional 100Gb/s optical standards such as 100GBASE LR4, 100GBASE […]
