Application Scenarios of CFP Transceiver Modules

 CFP optical transceiver modules are mainly used in switches, routers, converters, OTN optical transmission platforms and other equipment for line-side optical transmission of 100G wavelength division systems. Compared with other forms of line-side optical modules, It has good OSNR performance, sensitivity, dispersion tolerance, and DGD tolerance. At the same time, CFP coherent optical modules using wavelength division multiplexing technology are widely used in 100G metropolitan area networks to meet their high-capacity and long-distance requirements.

100G Multi-channel DWDM Transmission Network
Since 100G is more susceptible to dispersion, it is necessary to dispersion and improve optical power. First, a 100GHz DWDM multiplexer is used to combine all 100Gs, and then the dispersion compensation and amplification of the whole combination are performed. This architecture supports "pay-as-you-grow" service providers. Existing legacy 10G channels can be seamlessly swapped with 100G services when bandwidth is exhausted. The rest of the same components can even be reused to extend the data rate to 2.4Tb/s.

This solution requires 24 color CFP optical transceiver modules and a 48-channel 100GHz DWDM multiplexer. First, all 100G lines are multiplexed together, and then only one dispersion compensation and amplification is required. Obviously, such a network structure can provide higher density at a reasonable cost, and has the ability to flexibly reuse the existing infrastructure.

100G Distance Extension Solution
SFP + OEO Optical amplification repeaters can be used in conjunction with switches to achieve distance extension. After the 100G output signal of the switch is converted into a DWDM signal, it can realize longer distance transmission. This solution eliminates the distance limitation problem by using CFP coherent optical transceiver modules to connect the output signal to the line fiber to achieve longer distance signal transmission.

The above architecture achieves longer-distance signal transmission by adding MTP branch cables and WDM SFP + OEO converters, 6-channel dual-fiber DWDM dense wavelength division multiplexers and 8-channel dual-fiber CWDM coarse wavelength division multiplexers. The role of OEO is to convert conventional SR wavelengths to DWDM wavelengths. Therefore, the 100G CFP coherent optical module is an effective solution for building a 2500km long-distance DWDM network.

What Is Transponder and Muxponder?

 Data centers and service providers face the increasing demands for data security, low latency, higher speeds and longer distances in networks. Transponders and muxponders are both key elements that receive and send the signals over the fiber in an optical transport network.

What Is Transponder?
Transponders are used to enable point-to-point connections over long distances when the client rate matches the optical wavelength. A transponder is the element that sends and receives the optical signal from a fiber in optical fiber communications. A transponder is typically characterized by its data rate and the maximum distance the signal can travel. Transponders are used to enable point-to-point connections over long distances when the client rate matches the optical wavelength. In cases where the client rates are lower than the optical wavelength, a muxponder is used to multiplex multiple sub-rate clients onto the line interface.

What Is Muxponder?
In cases where the client rates are lower than the optical wavelength, a muxponder is used to multiplex multiple sub-rate clients onto the line interface. Muxponder is used in WDM or ROADM equipment, which needs to meet the needs of any service, port Muxponder or function card on the basis of reducing power consumption and cost. Muxponder also has the capability to combine multiple services into a single wavelength by multiplexing several channels to a higher order signal. 

200G Muxponer supports 100G or 200G OEO card. Its main function is to convert the service signals of 1*100G-QSFP28 into 1*100G-DCO coherent transceiver or 2*100G-QSFP28 to 1*200G-DCO coherent transceiver for coherent optical transmission. The line side adopts coherent optical modulation mode, and other technologies. It supports 100GE to 100G DWDM signal (100G CFP2 DCO) conversion and 2*100GE to 200G DWDM signal (200G CFP2 DCO) conversion and realize maximum transmission without repeater of 800 km, support C-band 96 channels (50GHz).

When to Use Transponders and Muxponders?
Transponders and muxponders can automatically receive, amplify and re-transmit signals on new wavelengths without any changes to the data carried over the signal at all, which can not be achieved by only adopting transceivers. However, a solution based on active transponders or muxponders is preferable when transceivers and switches are not fully compatible or when transceivers alone could not meet the real needs. 

1.When the networks need to be encrypted, transponders and muxponders can help to protect sensitive data and meet regulatory requirements with encryption.

2.When data needs to be transmitted over a long distance but the transceiver does not support long–distance WDM, an OEO-based solution with transponders and muxponders can extend the distance of WDM network and add FEC to the signal.

3.When an Internet service provider need to hand off a gray signal to end users, transponders and muxponders can help to control and restrict the bandwidth.

4.When the data needs to be transmitter at higher speeds than supported by transceivers in WDM networks, transponders and muxponders are another way to support faster speeds regardless of the transceiver form factor.

Characteristics of circulators

 

The prominent feature of the circulator is unidirectional transmission of high-frequency signal energy, which controls the electromagnetic wave transmission in a certain direction, and is mostly used between the output end of the high-frequency power amplifier and the load, which is independent and "isolated" from each other. The load impedance does not affect the working state of the power amplifier even in the case of open or short circuit, thus protecting the power amplifier. The annular device has the characteristics of small volume, wide frequency band and small insertion loss
