As shown in figure 11 each transceiver transmits over four fibers and also receives transmissions over four fibers.
Qsfp 40g sr4 cable.
Digital optical monitoring dom support is also present to allow access to real time operating parameters.
The cisco 40gbase csr modules support link lengths of 300 meters and 400 meters respectively on laser optimized om3 and om4 multimode fibers.
To connect a qsfp to qsfp we usually use a mtp 12 fiber trunk cable.
It primarily enables high bandwidth 40g optical links over 12 fiber ribbon r cables terminated with mpo mtp multi fiber connectors.
The qsfp 40g csr s is a pluggable optical transceiver with a duplex lc connector interface used for connectivity using multimode fiber mmf.
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.
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.
As we all know the standard specifies mpo as a connector to the 40gbase sr4 csr4 qsfp transceiver.
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.
Qsfp 40g sr4 item weight 1 6 ounces product dimensions 7 2 x 5 9 x 1 9 inches item dimensions lxwxh 7 2 x 5 9 x 1 9 inches processor count 1 voltage 240 volts manufacturer cisco systems 605824 asin b00a4s1j62 is discontinued by manufacturer no date first available february 25 2013.
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 cisco qsfp 40g csr4 is optimized to guarantee interoperability over the complete specification range of 10gbase sr.
