QSFPP-40G-LR4-PSM 40Gbps QSFP+ Transceiver, Single Mode, 10km Reach

1 Description

The QSFPP-40G-LR4-PSM is a transceiver module designed for 10km optical communication applications. The design is compliant to 40GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a

40Gb/s input into 4 channels signals, and converts them to 4 channel output electrical data.

The central wavelengths of the 4 channels is 1310 nm as members of the wavelength grid defined in ITU-T G694.2. It contains a MTP/MPO connector for the optical interface and a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long- haul system, single-mode fiber (SMF) has to be applied in this module.

The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

The module operates from a single +3.3V power supply and LVCMOS/LVTTL global control signals such as Module Present, Reset, Interrupt and Low Power Mode are available with the modules. A 2-wire serial interface is available to send and receive more complex control signals and to obtain digital diagnostic information. Individual channels can be addressed and unused channels can be shut down for maximum design flexibility.

The QSFPP-40G-LR4-PSM is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.
