As a vital part of the 100G network, 100G optical transceivers are ending up being increasingly more prominent. At the exact same time, the cost of the connected element fiber (PSM4) and a a great deal of elements (consisting of PSM4 and CWDM4) are decreased, and the 100G optical transceiver is ending up being increasingly more prominent.

What are the kinds of 100G optical transceiver components?

What standards do they comply with?

How ought to the appropriate 100G optical transceiver component be chosen?

100G transceiver standards

The transmission range of optical component is split into short range(2km and below), medium range (2 - 40km), and long range (40km and above); presently, the brief and tool vary inhabits the primary market share in information interaction optical modules. There are 2 essential basic organizations for optical components, IEEE and MSA (Multi Resource Agreement), which enhance and gain from each various other. The requirements starting with 100G are suggested by IEEE802.3.


Since the introduction of the 100G network, IEEE, multi-source Procedure (MSA) and so forth suggested a range of requirements for the 100G transceiver. In these requirements, the PSM4 and CWDM4 requirements designed by MSA market companies are better for 100G QSFP28 optical transceivers on the market.

CFP transceiver introduction

CFP is determined by multi-source contract (MSA) to specify the form-factor of the optical transceivers for high-speed electronic indicate transmission. This MSA was mainly designed for 100 Gigabit Ethernet systems and the "C" in "CFP" means the Latin letter C utilized to reveal the number 100. The electric link of a CFP utilizes 10x10 Gbit/s lanes in each instructions (RX, TX). While, the optical link can assistance both 10x10 Gbit/s and 4x25 Gbit/s variations of 100 Gbit/s interconnects. 100G CFP provide connection choices for a wide variety of provider transfer, information facility networking, and business core aggregation applications.

QSFP28 transceiver introduction

QSFP28 is a hot-pluggable transceiver component developed for 100G information link in telecom, information facilities and networking markets. The "Q" of QSFP28 implies quad (4 networks). QSFP28 integrates 4 transfer and 4 get networks. "28" implies each lane brings as much as 28G information price. QSFP28 transceiver can do 4x25G outbreak link, or 1x100G link depending upon the transceiver utilized.

For instance, you can utilize 100G QSFP28 to 4 SFP28 DAC cable televisions to recognize 4x25G outbreak link and LC-interface centered QSFP28 with a solitary setting fiber (or MTP/MPO-interface centered QSFP28 transceiver with a 12-fiber MTP/MPO spot cable television) to obtain 1x100G link straight.


The initially generation QSFP optical transceiver is geared up with 4 TX and RX ports, with a price of 10Gbps each network. For QSFP28 optical transceivers, each network of the 100G transceiver can send out and get as much as the information of the 28Gbps. Compared to the CFP4 optical transceiver, the QSFP28 optical transceiver is smaller sized compared to the CFP4 optical transceiver. Although the QSFP28 optical transceiver has the benefit of surpassing the CFP4 optical transceiver, the CFP4 optical transceiver has greater power usage, that makes it better for long-distance optical transmission.
