Transceiver/40GBase-SR4 QSFP Module MPO
The cisco® 40gbase qsfp+ (quad small form-factor pluggable plus) modules offer customers a wide variety of high-density 40 gigabit ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider transport applications. Main features of cisco 40gbase qsfp+ modules include: - support for 40gbase ethernet - hot-swappable input/output device that plugs into a 40-gigabit ethernet qsfp+ cisco switch port - flexibility of interface choice - interoperable with other ieee-compliant 40gbase interfaces available in various form factors - support for "pay-as-you-populate" model - support for the cisco quality identification (id) feature which enables a cisco switch to identify whether the module is certified and tested by cisco cisco qsfp-40g-sr4 the cisco 40gbase-sr4 qsfp+ module supports link lengths of 100m and 150m respectively on laser-optimized om3 and om4 multimode fiber cables. It primarily enables high-bandwidth 40g optical links over 12-fiber ribbon r cables terminated with mpo/mtp multi-fiber connectors. It can also be used in 4x10g mode along with ribbon to duplex fiber breakout cables for connectivity to four 10gbase-sr optical interfaces. Maximum channel insertion loss allowed is respectively 1.9db over 100m of om3 cable or 1.5db over 150m of om4 cable. Cisco qsfp-40g-csr4 the cisco 40gbase-csr4 qsfp+ module is similar to the 40gbase-sr4 interface extends supported link lengths to 300m and 400m respectively on laser-optimized om3 and om4 multimode fiber cables. Each 10-gigabit lane of this module is compliant to ieee 10gbase-sr specifications. This module can be used for native 40g optical links over 12-fiber ribbon cables with mpo/mtp connectors, or in 4x10g mode with ribbon to duplex fiber breakout cables for connectivity to four 10gbase-sr interfaces. Maximum channel insertion loss allowed is respectively 2.6db over 300m of om3 cable or 2.9db over 400m of om4 cable. Cisco qsfp-40ge-lr4 the cisco 40gbase-lr4 qsfp+ module (figure 2) supports link lengths of up to 10km over a standard pair of g.652 single-mode fiber with duplex lc connectors. The 40 gigabit ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.
