Cisco QSFP-100G-LR4-S Compatible 100GBASE-LR4 QSFP28 Optical Transceiver (SMF, 1295~1310nm, LC, 10km, DOM)
100G QSFP28 1310nm 10km
This 100GBASE-LR4 QSFP28 transceiver is compatible with Cisco networking equipment and equivalent to Cisco QSFP-100G-LR4-S. It is suitable for long distances and offers a highly cost-effective way to establish a 100 Gigabit link connectivity between devices using QSFP28 ports. The compatible QSFP-100G-LR4-S converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. The transceiver supports link lengths of up to 10km over single-mode fiber (SMF) at the wavelength specified between 1295nm and 1310nm using a duplex LC connector.
Features
• Functionally identical to Cisco QSFP-100G-LR4-S
• Up to 26Gb/s data rate per channel
• QSFP28 MSA compliant
• Up to 10km on single mode Fiber
• Single 3.3V power supply
• Maximum power consumption 3.5W
• Duplex LC optical connector
• Built-in digital diagnostic function
