Based on an industry multi-standard agreement (SWDM-MSA), more open interoperability than other proprietary solution like QSFP-SR-BD
Cost effectively bandwidth upgrading from 10G to 40G without changing existing fibers
Description
The GTQ-L08A4-02DC is a kind of pluggable optical transceiver uses SWDM (Short Wavelength Division Multiplex) technology working with multimode fiber, providing 4 channels in the 850-940nm region at 10Gbps/lanes, which can transmit a multiplexed 40G signal over wide band OM5 at lengths up to 440m(240m on OM3/350m on OM4) with an duplex LC connector.
Uses two fibers (duplex) instead of eight (SR4), this 40G SWDM4-S is a more cost effective transceiver solution for 10G to 40G migration applications.
The QSFP+ 40Gbase-SWDM4 transceivers are compliant with the QSFP+ MSA and IEEE 802.3ba XLPPI electrical interface.
Digital diagnostics functions are available via an I2C interface, as specified by the QSFP+ MSA.
