Why CPAK Transceiver Is Different in 100G Solutions? With the rising demands for bandwidth from fast-growing cloud services and data centers, all network components are continuing to keep pace with the trend to meet the expectations of the end users. While the connectors are moving from LC to MTP type, the optical transceivers are also progressing in line with the emerging trends. 100G transceiver market is booming and will be more popular in the near future. view EGS page In 2013, Cisco announced its proprietary 100G transceiver called CPAK. The CPAK transceiver has been able to offer something interesting to 100G technology buyers. But what makes CPAK transceiver different from other 100G transceiver? Let’s unveil its mystery.
CPAK transceiver was launched in the market later than CFP2. Its appearance is similar to the CFP2 optical transceiver, but the interface uses the IEEE standard to support compatibility with other interfaces, so as to make them well suit for connections in service provider data center, enterprise and edge networks. This kind of 100G transceiver has generally 82 pins on its electrical interface (40 pins on the top row and 42 on the bottom row), and there is a duplex SC or 12-fiber /24-fiber MPO/MTP connector on its optical interface. CPAK 100GBASE optical module can be plugged into the CPAK ports of Cisco switches and routers. To offer a flexible selection, 100G CPAK modules accommodate a variety of distance and fiber type requirements, so you can choose the model in line with your requirements.
To face the exploding demand of network bandwidth, there are many options for 100G modules, like CFP, CFP2, CFP4, QSFP28, CPAK. So the competition among 100G optical transceivers remains fierce. Under this condition, what makes 100G CPAK module different from other 100G transceiver modules? And what are the benefits of CPAK transceiver? The most difference is that CPAK transceiver is the first 100G optical module using CMOS photonics which bring extremely efficient low-power optical circuits, and it is Cisco propriety. Besides, CPAK optical transceiver incorporates IEEE standard interfaces available in several different types: 100GBASE-SR10, 100GBASE-ER4L, 100GBASE-LR4, 10x10G-ERL, 10x10GBASE-LR, etc. Generally, different 100G module types can communicate with each other under the same standard and the same speed rate. For example, 100GBASE-LR4 whether from CFP/CFP2/CFP4 or CPAK will be inter-operate.
