GIGALIGHT’s 40G QSFP+ eSR4 optical transceiver modules are designed for short-distance interconnection between devices within data centers. They comply with the IEEE 802.3ba 40GBASE-SR4 Ethernet transmission protocol and offer optional dual-rate versions supporting 40GE/OTU3. These modules utilize 4 pairs of parallel multimode fibers for transmission, with a center wavelength of 850nm. The maximum transmission distance is 300m (OM3 MMF) or 400m (OM4 MMF). Industrial-grade operating temperature range options are available.
