Overview
The CFP-100GBASE-LR4 is 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 module has a Gearbox to aggregate 10x10G signals into 4x25G data-streams. 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 CFP MSA Hardware Specification Revision 1.4.
Specifications
Functional Diagram
This product converts the 10-channel 10Gbps electrical input data into 4 channel WDM optical signals, using a gearbox. 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 which is then converted into 10-channel 10Gbps electrical output data. Figure 1 shows the functional block diagram of this product.
