Description The 40G QSFP+ LR4 is a transceiver module designed for 10km optical communication applications. (SMF, 1310nm, 10km, LC, DOM) Compliant with 40GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDMoptical signals and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4CWDM channels signals and converts them to 4-channel output electrical data. 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. 100G QSFP28 SR4 100G QSFP28 LR4 100G QSFP28 SR BIDI 100G QSFP28 CWDM4 100G QSFP28 ER4 100G QSFP28 PSM4 Buying Options Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 5.0 out of 5 stars 2 5.0 out of 5 stars 2 5.0 out of 5 stars 2 5.0 out of 5 stars 2 5.0 out of 5 stars 2 5.0 out of 5 stars 2 Price — no data $449.99$449.99 $569.99$569.99 $229.99$229.99 $2,000.99$2,000.99 $279.99$279.99 Max Data Rate 103.125Gbps (4x 25.78Gbps) 103.125Gbps (4x 25.78Gbps) 103.125Gbps (4x 25.78Gbps) 103.125Gbps (4x 25.78Gbps) 103.125Gbps (4x 25.78Gbps) 103.125Gbps (4x 25.78Gbps) Wavelength 850nm 1295.56nm, 1300.05nm 1304.58nm, 1309.14nm 850nm & 900nm 1271nm, 1291nm, 1311nm, 1331nm 1295.56nm, 1300.05nm 1304.58nm, 1309.14nm 1310nm Max Cable Distance 100m on OM4 70m@OM3 10km 100m@OM4 75m@OM3 / 150m@OM5 2km 40km 500m Connector MTP/MPO-12 LC Duplex LC Duplex LC Duplex LC Duplex LC Duplex Media MMF SMF MMF SMF SMF SMF Transimitter Type VCSEL 850nm PIN 4 x LAN WDM DFB PIN VCSEL 850/900nm PIN 4 x CWDM DFB PIN 4 x LAN WDM EML APD 4 x LAN WDM DFB PIN Power Consumption ≤1.8W ≤3.5W ≤3.5W ≤3.5W ≤4.5W ≤3.5W Support DDM/DOM Hot FEC DDM/DOM Hot FEC DDM/DOM Hot FEC DDM/DOM Hot FEC DDM/DOM Hot FEC DDM/DOM Hot FEC Commercial Temperature Range 0 to 70°C (32 to 158°F) 0 to 70°C (32 to 158°F) 0 to 70°C (32 to 158°F) 0 to 70°C (32 to 158°F) 0 to 70°C (32 to 158°F) 0 to 70°C (32 to 158°F) Protocols IEEE 802.3bm, QSFP28 MSA, SFF-8665, SFF-8636, RoHS, CPRI, eCPRI IEEE 802.3ba, IEEE 802.3bm, 100G CWDM4 MSA, QSFP28 MSA, SFF-8665, SFF-8636 Data Center, 100GBASE Ethernet QSFP28 MSA Compliant IEEE 802.3ba, IEEE 802.3bm, 100G CWDM4 MSA, QSFP28 MSA, SFF-8665, SFF-8636 100G Ethernet QSFP28 MSA Compliant IEEE 802.3ba 100GBASE-LR4, IEEE 802.3bm, QSFP28 MSA, SFF-8665, SFF-8636 Fiber Mall is committed to providing integrated cost-effective optical communication products, one-stop solutions and service support for global data centers, cloud computing, enterprise networks, access networks and wireless networks.
