Overview
The CFP2-100GBase-LR4is a 100G transceiver module designed for applications over single-mode (SM) fiber with transmission distances of up to 10km. The module supports both 100GBASE-LR4 and OTU4 operation. It uses 4 WDM optical signals (around 1310nm), and multiplexes them into a single channel for 100Gbps optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 100Gbps LR4 input into 4 WDM channels signals, and converts them to electrical data. The central wavelengths of the WDM channels are 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm according to the IEEE LR4 recommendation. The module contains a duplex LC connector for the optical interface and a 148-pin connector for the electrical interface. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the CFP2 MSA hardware specification.
Specifications
Functional Diagram
This product converts the 4x 28Gbps electrical input data into 4 channel WDM optical signals. The WDM light signals are combined by an optical MUX to a 103 or 112 Gbps data stream. The connector interface towards the SM fiber is LC. The receiver part accepts 103 or 112Gbps WDM optical signals and de-multiplexes them into 4 individual channels. Each wavelength is received by a photo diode (PIN) and converted into an electrical signal of 25Gbps or 28Gbps. Figure 1 shows the functional block diagram of this product.
