NADDOD-Building an Intelligent World with Everything Connected

With the rapid development of optical communication and Internet, the demand for network has also grown in line with the trend, resulting in the rapid growth of traffic in telecom backbone network at the rate of 50% to 80% per year. To meet user demand, the transmission rate of optical communication has increased its development, from 10G, 25G, 40G before to 100G, 200G, 400G, etc. today. Although 100G optical transceivers have become the mainstream of the market, the bandwidth and port density requirements are still increasing, which further drives the technology to 200G, 400G or higher speed systems. What Are the Package Types of 200g Optical Modules? Currently, there are two main types of 200G optical transceivers: 200G QSFP56 and 200G QSFP-DD. The QSFP56 was introduced in 2017 and by its very nature represents a design advancement from earlier QSFP transceivers, while the QSFP-DD was still in the development stage during the same time frame. Both are designed for high-performance co...

What are the advantages of using 400G optical transceivers and cables? 1. Greater transmission density per RU: from a single port rate 100G to 400G, the transmission bandwidth per RU from 3.2–3.6T to 12.8–14.4T/RU. 2. Greater connection density with servers: support 400G to 4X100G connections. 3. Reduce the complexity of cabling: with the same bandwidth, cabling only need a quarter of 100G. 4 .Lower power consumption: 400G transceiver power consumption is less than four 100G module power consumption, reducing operation and maintenance costs. What are the package forms of 400G optical transceivers and cables? 1. OSFP(Octal Small Form-factor Pluggable): Octal means 8, because the electrical interface of an OSFP module consists of eight electrical channels of 50G. 2. QSFP-DD(Octal Small Form-factor Pluggable-Double Density): QSFP-DD looks similar to QSFP, increasing the number of connecting fingers from four (QSFP) to eight (QSFP-DD) . Can I use QSFP-DD transceivers on OSFP ports? OSFP an...

At present, the technology of 100G Ethernet is becoming mature and the deployment of 100G Network by enterprises, institutions and governments has been gradually put on the right track. 100G optical transceiver has the characteristics of high port density, low power consumption and low cost. It is popular with data center and is usually used with 100G switch. NADDOD’s 100G optical transceiver is fully compatible with switches from Cisco, Arista, Juniper and so on, offering a full range of optical transceiver solutions to help users build cost-effective network systems. NADDOD 100G QSFP28 Optical Transceiver Module NADDOD 100G QSFP28 optical transceivers can satisfy the requirements of different transmission distance: short distance (2km or less), middle distance (2–10km), and long distance (10km or more). At present, among the three kinds of distance, the 2km middle distance occupies the main market share. NADDOD 2km QSFP28 optical transceivers are available in QSFP-100G-PSM4 and QSFP-...

  What Is Passive Optical Network (PON)? PON (Passive Optical Network) is a point-to-multipoint passive fiber access technology, originated in the 1990s. ITU-T G.982 gives the reference of PON function configuration, mainly contains three basic functional parts: Optical Line Terminal (OLT), Optical Network Unit (ONU) and Optical Distribution Network (ODN). The functions of the three parts are as follows: OLT:  Optical Line Terminal, which is simply understood as the “upstream” operator-side device of optical network transmission. It is used to communicate with the ONU on the user side through one or more ODN optical fiber distribution networks. The OLT and the ONU have a master-slave communication relationship. OLT manages signaling and monitoring information from the ONU; OLT equipment is generally deployed in the operator base station, or service node room. ONU:  Optical Network Unit, located between the ODN fiber distribution network and the user, is a user-side device...
