It primarily enables high bandwidth 40g optical links over 12 fiber ribbon r cables terminated with mpo mtp multi fiber connectors.
Qsfp 40g sr4 cable.
The cisco qsfp 40g sr4 compatible qsfp optical transceiver module is designed for use in 40gbase ethernet throughput up to 150m over om4 multimode fiber mmf using a wavelength of 850nm via a mtp mpo connector.
To connect a qsfp to qsfp we usually use a mtp 12 fiber trunk cable.
As shown in figure 11 each transceiver transmits over four fibers and also receives transmissions over four fibers.
Product description this cisco qsfp 40g sr4 compatible qsfp transceiver provides 40gbase sr throughput up to 150m over multi mode fiber mmf at a wavelength of 850nm using a mpo connector.
Qsfp 40g csr4 can be used for native 40g optical links over parallel cables with mpo mtp connectors or in a 4 10g mode with parallel to duplex fiber breakout cables for connectivity to four 10gbase sr interfaces.
40gbase sr4 our high performance qsfp 40g active optical cable aoc has been designed as a cost effective i o solutions for 40g ethernet and 10g fibre channel application with reliable 4ch 850nm vscel array and 4ch pin photo detector array technology using multimode fibre at 850nm.
Digital optical monitoring dom support is also present to allow access to real time operating parameters.
In the 40gbase sr transmission there are eight fibers associated with the channel four fibers for the tx signal and four fibers for the rx signal.
The qsfp 40g csr s is a pluggable optical transceiver with a duplex lc connector interface used for connectivity using multimode fiber mmf.
Part codes available lengths.
The cisco qsfp 40g csr4 is optimized to guarantee interoperability over the complete specification range of 10gbase sr.
As previously mentioned in 2010 ieee 802 3ba approved the 40gbase sr4 physical medium dependent pmd multimode parallel optic solution which uses eight fibers to transmit four duplex channels each at 10 gigabit ethernet.
