Continuing from the previous article, the most important category of optical modules is packaging. Gearlink will continue to introduce the packaging classification details of optical modules.
SFP28 is suitable for a single 25GE access port. SFP28 transceiver, based on SFP+ package form, supports 25G Ethernet standard. SFP28 can provide error-free transmission of 25Gb/s. The transmission distance can reach 100 meters in OM4 multimode fiber. It can also be used in high-density 25G Ethernet switches and network interfaces to promote server connections in data centers. It uses today's popular SFP+ packaging form to upgrade 10G Ethernet connections for enterprises, providing a more cost-effective solution. We also provide sfp+ transceiver for sale.
QSFP / QSFP+ transceiver
QSFP, the full name is Quad Small Form-factor Pluggable, a four-channel small form-factor pluggable optical module with four independent full-duplex transceiver channels. Its original intention was to replace the single-channel SFP with a high-density optical module. The QSFP is only 30% larger than the standard SFP module. QSFP was born to meet the market's demand for higher-density high-speed pluggable solutions. This 4-channel pluggable interface has a transmission rate of 4x10Gbps. Many mature key technologies in XFP have been applied to this design.
The packaging method of the 100G QSFP28 transceiver is the same as that of the 40G QSFP+ transceiver, and both use 4 fiber channels to transmit data. The difference is that the transmission rate of each fiber channel of the 100G QSFP28 transceiver can reach up to 28Gbps, which is mainly used for 100G transmission applications. Compared with 100G CFP transceivers, 100G QSFP28 transceivers are more adaptable to high-density wiring and are widely favored by most data centers. The 100G QSFP28 transceiver first appeared in 2013. After several years of development, it has derived multiple categories suitable for different transmission applications. We provide QSFP28 transceiver for sale.
QSFP-DD MSA was established in March 2016 and its members include 52 companies in the industry. The MSA is mainly dedicated to the development of optical modules with a higher speed than the existing QSFP28 modules, and can be backward compatible with QSFP. QSFP-DD adopts 8 electrical interfaces, each adopts 25Gbps NRZ or 50Gbps PAM4 signal format, and can support up to 400Gbps rate. In addition, 36 QSFP-DD transceivers can be inserted into a switch slot, providing a total capacity of 14.4Tbps. Welcome to consult for more information about QSFP-DD transceiver products.
Equipment manufacturers of optical modules will encrypt their devices to varying degrees, also known as compatibility. Modules of a particular brand can only be used with devices of the same brand, and cannot be matched with other brand optical modules. Compatibility manufacturers need to conduct different compatibility adaptations on the optical modules. Whether or not they can perfectly solve compatibility issues is particularly important.
