What is CPAK Optical Transceiver Module?
Designed as a smaller, low-rate alternative to CFP transceiver, CPAK 100GBASE optical module isn't always famous at the 100G market nowadays. CPAK module is also the first 100G optical transceiver that makes use of CMOS Photonics generation. This kind of 100GBASE module can paintings inside the following Cisco networking tool—ASR 9000 Series Router; CRS-X Carrier Routing System; NCS 2000, 4000, and 6000 Series Routers; the Nexus 7000 and 7700 Series Switches, and the Cisco ONS Transport Platform.
CPAK optical transceiver contains IEEE popular interfaces to be had in several one of a kind standards: 100GBASE-SR10, 100GBASE-ER4L, 100GBASE-LR4, 10x10G-ERL, 10x10GBASE-LR, and so forth. CPAK transceivers can support 10X10Gbps and 4X25Gbps mode for an mixture of 100Gbps data fee (seen within the above photo). It can operate high-density 10G breakout with MPO-24 cables, CPAK-100G-SR10 is operating on this type, which is also backward well suited with 10GBASE-SR. CPAK LR4 module is well matched with different 100GBASE-LR4 compliant modules consisting of CFP to aid high-bandwidth 100Gb optical hyperlinks over standard single-mode fiber terminated with SC connectors.
The foremost functions of CPAK modules are backward compatibility, smaller form component and power efficiency.
CPAK Vs. CFP/CFP2/CFP4
As mentioned before, CPAK turned into launched right after CFP modules. Although CFP is the pioneer in 100G optics, but its huge length can not meet the needs of high-density statistics center. Therefore, CFP2 and CFP4 with extra compact sizes are evolved. When comparing CPAK with CFP modules, CPAK transceivers are less than one third the dimensions of CFP modules, and use up much less than one 0.33 the electricity. In a evaluation with CFP2 modules, CPAK optical transceivers are 20% smaller and eat 40% much less energy. In different phrase, in case you use CPAK other than CFP2 modules for your statistics center switches, it could offer 20% greater port density and the front-panel bandwidth.
In brief, CPAK optical module has smaller footprint than CXP, CFP and CFP2, but bigger than CFP4 and QSFP28 optics. Besides, CPAK 100GBASE-LR4 consumes less than five.5W, that's much less than CFP LR4 (24W), CFP2 LR4 (12W), CFP4 (9W) and CXP LR4 optics (6W) however a touch better than QSFP28 (3.5W). CPAK represents a extensive development in optical networking, supplying dramatic area and energy performance.
CPAK Vs. QSFP28
QSFP28 optical transceiver, due to its smallest shape aspect and lowest strength consumption, is seemed as the maximum promising 100G optical module. In terms of the form component, QSFP28 is more compact then CPAk modules. As to the electricity intake, Cisco CPAK 100GBASE-LR4 module helps link lengths of up to 10 km over trendy single-mode fiber with SC connector with a nominal power intake of less than 5.5W. QSFP28 100GBASE-LR4 supports as much as 10km and consumes almost 3.5W.
QSFP28 transceiver is designed for 100G speeds and the use of the four×25 wiring specification. 100G QSFP28 SR4 is designed for quick-haul transmission and QSFP28 LR4 is designed for long-haul transmission.
Summary
In 2017, 100G era and applicable optical transceivers regularly become matured. 100G optics like CXP, CFP/CFP2/CFP4, 100G QSFP28 in distinct requirements gives a large selection for customers. CPAK module was released simply days after the certification of CFP2 optics. It is famous for the smaller footprint and electricity financial system. However, whilst competing with open source MSA well matched 100G merchandise (CFP/CFP2/CFP4 and QSFP28), CPAK isn't always the suitable one for 100G excessive-density connectivity. However, many third birthday party optical solution carriers like 10Gtek.COM announce to help market to cut down this pricing and shop budgets for customers. 10Gtek.COM will release this cable in the close to destiny, if you are involved, please touch us.
