Brief Introduction

The QSFP-40G-SR-BD-VC is a transceiver module designed for optical transmission applications over both MMF and SMF with transmission distances of up to 150m on MMF (OM3) and 2km on SMF.

The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM 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 CWDM channels signals, and converts them to 4 channel output electrical data.

The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. It 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 QSFP+ Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. For applications over OM3/OM4 MMF, MMF cables are directly connected to the LC connectors of QSFP+ LX4 module and optical signal is directly launched from the transmitter into the MMF cable.

For applications over SMF, the module is used as a QSFP+ IR4 module and SMF cables are directly connected to the LC connectors of the module as shown in the following.
