Product Descriptions

Olinkcom's QSFP-40G-SR4 is designed for use in 40 Gigabit Ethernet (40GbE) applications over multi-mode fiber. It complies with QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4 specifications. The QSFP+ SR4 transceiver integrates four data lanes in each direction with each lane to giving an aggregated 40 Gbps bandwidth. Each lane supports link lengths of 100m on OM3 multi-mode fiber or 150m on OM4 multi-mode fiber. The optical transmitter incorporates a 4-channel 850nm VCSEL laser, a 4-channel input buffer and laser driver, control and bias blocks. The optical receiver incorporates a 4-channel PIN photodiode, a 4-channel TIA array, a 4 channel output buffer, control blocks.
