CFP4 Transceiver,100G,SR4

Description
The F-tone Networks’s100Gb/s transceiver module for optical communication applications compliant to 100GBASE-SR4 of the IEEE P802.3bm standard. The module converts 4 input channels of 25Gb/s electrical data to 4 channels of VCSEL optical signals over 4 multimode fibers for 100Gb/s optical transmission. Reversely, on the receiver side, the module receives 4 channels of VCSEL optical signals over 4 multimode fibers and then converts them to 4 output channels of electrical data.
The high speed VCSEL transmitters and high sensitivity PIN receivers provide superior performance for 100Gigabit Ethernet applications up to 100m links over OM4 multimode fibers and compliant to optical interface with IEEE802.3bm Clause 95 100GBASE-SR4 requirements.
This product contains an MTP/MPO optical connector for the optical interface and a 56-pin connector for the electrical interface. Figure 1 shows the functional block diagram of this product.
The CFP4 module supports the MDIO interface specified in IEEE802.3bm Clause 45. It supportsalarm, control and monitor functions via hardware pins and via an MDIO bus. Upon module initialization, these functions are available. CFP4 MDIO electrical interface consists of 6 wires including 2 wires of MDC and MDIO, as well as 3 Port Address wires, and the Global Alarm wire. The CFP4 uses pins in the electrical connector to instantiate the MDIO interface as listed in Table 1. MDIO Interface Pins.
