Dell Q28-100G-CWDM4 0THPF3 LQ21DCR-CAA1-DL3 100G CWDM4 2km Single-Mode QSFP28 Transceiver

Basic Parameter Table

Core Product Features

1. Dell OEM 100G CWDM4 single-mode QSFP28 optical transceiver, fully compatible with Dell PowerEdge 14G/15G/16G rack servers and Dell QSFP28 enterprise leaf/spine switches.
2. Adopts four CWDM parallel wavelength design complying with 100GBASE-CWDM4 standard, supporting up to 2km transmission over standard G.652 single-mode fiber with LC duplex interface.
3. Hot-swappable QSFP28 housing equipped with full DDM (Digital Diagnostic Monitoring), enabling real-time monitoring of each lane’s Tx/Rx optical power, module temperature and supply voltage.
4. Industrial wide-temperature low-power hardware design, stable 24/7 continuous operation in medium and large cloud data center cabinet environments.
5. Four independent 25G CWDM channels integrated inside, ideal for same-building medium-distance backbone interconnection without expensive long-haul DWDM equipment.
6. Green pull tab identifier for easy distinction from multi-mode SR4 modules; single-mode design breaks the distance limit of multi-mode fiber for cross-floor inter-building links within 2km.

Application Scenarios

1. Medium-distance interconnection between main and auxiliary data centers on the same campus, core switch backbone uplink, storage cluster fiber interconnection within 2km.
2. Multi-floor enterprise building network backbone, short metro campus interconnection relying on existing single-mode cabling infrastructure.
3. Not suitable for ultra-long-distance cross-city transmission and short-range intra-rack multi-mode wiring scenarios.
