Cisco QSFP-100G-ER4L-S Compatible 100GBASE-ER4L QSFP28 optical transceiver module at 1310nm/40km Duplex LC/UPC SMF supports transmission rates of up to 100Gbps over single-mode fiber up to 40 km at the 1310nm wavelength. The transceiver uses EML transmitters and SOA + PIN receivers, has a maximum power consumption of 4.5 W, and operates reliably in the ambient temperature range of -20°C to 85°C.
This hot-pluggable QSFP28 module is digital diagnostic monitoring (DDM) capable, delivering real-time operational and troubleshooting data to the module when in service. The metal enclosure reduces EMI and improves thermal management, while the BOX packaging design provides both high reliability and heat dissipation to ensure proper cooling and extended operating life. The transceiver complies with IEEE 802.3ba, QSFP28 MSA (SFF-8665, SFF-8679), RoHS, and Class 1 FDA laser safety standards. The transceiver is interoperable with IEEE-compliant 100G Ethernet interfaces, offering reliable network compatibility and interoperability. It is ideal for use in data centers, enterprise core, and campus networks and has been rigorously tested for reliable first-class performance by each respective switch manufacturer.
