The center wavelength of QSFP+40G optic transceiver is 1271nm, 1291nm, 1311nm and 1331nm. It’s a single mode with duplex LC interface, supporting DDM. Its operating temperature is 0°C to 70°C, and the transmit optical power is -2.7 to +4.5dBm. Generally, it is used in data center and metro optical transmission network with single-mode patch cord OS2, and the transmission distance can reach up to 40KM.
This transceiver is compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 and OTU3 C4S1-2D1 standard. The Cisco QSFP-40GE-LR4 Compatible QSFP+ Optical Transceiver Module is designed for use in 40GBASE Ethernet throughput up to 10km over single mode fiber (SMF) using a wavelength of 1310nm via duplex LC connectors. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ MSA, to allow access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as data centers, high-performance computing networks, enterprise core and distribution layer applications.
Network Connectivity
40G Connectivity for Data Center
40G QSFP+ optical module provides high-density and low-power 40G Ethernet connection transmission applications.
Tested in Host Devices for Proven Interoperability
40G SR4 QSFP+ optical module complies with 802.ba D3.2 (40GBASE-SR4) standard and can be connected to MPO/MTP fiber optic connectors for 40G transmission applications.
In data centers, high-performance computing networks, enterprise core layer and distribution layer application scenarios, 40G QSFP+ optical modules provide high-density and low-power 40G Ethernet connection transmission applications.
Actually, 40G-SR4 modules adopted MTP/MPO-12 Male connectors, but only 8 fiber strands are required, 4 fibers are idle in the connection, so you can use both 8 fibers and 12 fibers MTP cables.
QSFP+ LR4 40G 10KM transceiver primarily enables high-bandwidth 40G optical links over duplex single mode fiber patch cable with LC connectors or MPO trunk cables.
40km.
Unitekfiber supply a huge volume of optic transceiver modules, most of transceiver modules have a short lead time, 5-7days.
Unitekfiber's optical modules are compatible with Fiberhome, Huawei, ZTE, Cisco, Ericsson, Nokia and other brands.
Great fiber. Keep me regular. Worked as intended.
