Dell QSFP-40G-LR4 0H93DH JQPR04LWBA1DL 40G Single-Mode QSFP+ Transceiver

Basic Parameter Table

Core Product Features

1.  Dell OEM 40G long-reach single-mode QSFP+ optical transceiver, fully compatible with Dell PowerEdge rack servers and Dell enterprise QSFP+ core switches.
2. Adopts CWDM four-wavelength parallel design compliant with 40GBASE-LR4 standard, supporting up to 10km long-distance transmission over standard G.652 single-mode fiber with LC duplex interface.
3. Hot-swappable QSFP+ form factor equipped with DDM (Digital Diagnostic Monitoring), which supports real-time monitoring of each lane’s transmit/receive optical power, operating temperature and supply voltage.
4. Industrial wide-temperature low-power hardware design, delivering stable 24/7 continuous operation in core data center equipment cabinets.
5. Four independent 10G CWDM channels integrated inside, widely deployed for campus cross-building backbone, remote IDC interconnection and long-distance storage fabric uplink.
6. Long-reach single-mode advantage: breaks multi-mode fiber distance limit, ideal for cross-building, cross-floor and remote data center backbone networking.

Application Scenarios

1. Long-distance interconnection between campus main and branch data centers, core switch backbone uplink, remote backup storage cluster 40G fiber interconnection within 10km.
2. Metropolitan enterprise multi-building network backbone, inter-floor long-distance fiber transmission relying on single-mode cabling infrastructure.
3. Not suitable for short-range intra-rack interconnection and multi-mode fiber wiring environments.
