02311BKT Compatible Transceiver 40GbE QSFP+ 40KM SMF for Cloud MAN

To distribute service in multi-regions, enterprise adopts cloud network to interconnect central and branch offices and manage cloud assets, software and applications. In a normal scenario, the private cloud uses a direct fiber connection to create Cloud WAN with flexible bandwidth, comprehensive security functions, light, and high-speed connection. The multiple LANs in the different sites are interconnected by the metropolitical network across buildings, regions, and even cities. These connections are created by the high-speed backbone fibre link over the range of 10 to 50km with the bandwidth of 25Gbps, 40Gbps and even 100Gbps.

Top-Trans QSFP+-40G-ER4 is a 40GbE transceiver used for Cloud WAN, equivalent to HW 02311BKT, QSFP-40G-ER4, with excellent interoperability with Cloud Engine S7700 and S12700 series switches. This QSFP+ module features the parallel Quad Small Form-Factor Pluggable (QSFP) with four independent CWDM DFB transmitters and APD receivers. This QSFP module creates the data link of 40GBASE-ER4 over 40KM Singlemode OS2 fiber via a dual LC connector. This QSFP+ module is fully compliant with IEEE 802.3by, IEEE 802.3cc, SFF-8402, SFF-8472, 21CFP-1040 LC#50 7/2001. It features build-in DDM/DOM via the I2C Interface to monitor the operating status.
