Fujitsu compatible FIM37000/173 Description
The EDGE 100G-QSFP28-80 is a direct replacement for the Fujitsu FIM37000/173, coded with Fujitsu-recognized EEPROM data. The module is accepted on Fujitsu 1FINITY and FLASHWAVE platforms without additional configuration. Same LC duplex connector, same 80km single-mode reach.
The module uses four LAN-WDM wavelengths (1295.56, 1300.05, 1304.58, 1309.14nm) across a duplex LC single-mode fiber pair. Line rate is 103.125 Gbps (4 lanes at 25.78125 Gbps each, 64B/66B encoded). Rated for a 30dB maximum optical link budget with FEC, supporting links up to 80km over OS2 single-mode fiber. Operating temperature 0 to 70°C.
Fujitsu uses FIM37000-series part numbers for 100G ZR4 optics deployed on their optical networking platforms, including the 1FINITY series (T300/T310 transport, S100/S900 switching) and FLASHWAVE 4300/9500 systems. These platforms accept standard QSFP28 MSA-compliant modules in their client-side ports.
Fujitsu lists two variants in the FIM37000 ZR4 family: FIM37000/172 and FIM37000/173. Both share the same 100GBASE-ZR4 optical specifications and 80km reach. The suffix denotes the hardware revision. The EDGE replacement is compatible with both. If your spares list or purchase order references FIM37000/173, this is the correct module.
The module conforms to the 100GBASE-ZR4 MSA and the QSFP28 Multi-Source Agreement. DDM/DOM per SFF-8636 provides real-time readings for transmit power, receive power, temperature, voltage, and bias current through the platform management interface.

Frequently Asked Questions
What is the difference between FIM37000/173 and FIM37000/172?
Both are Fujitsu 100GBASE-ZR4 QSFP28 modules with the same optical specifications and 80km reach. The /173 and /172 suffixes denote different hardware revisions within the FIM37000 ZR4 family. The EDGE replacement (100G-QSFP28-80) is compatible with both variants. Check your Fujitsu platform documentation to confirm which suffix is specified for your deployment.
Which Fujitsu platforms use the FIM37000/173?
The FIM37000 series is used on Fujitsu optical networking platforms with QSFP28 client-side ports, including the 1FINITY family (T300/T310 transport blades, S100/S900 switching) and FLASHWAVE 4300/9500 packet-optical platforms. These systems use standard QSFP28 MSA ports for client-side 100G connections.
What does FIM37000 mean in Fujitsu's part numbering?
FIM is Fujitsu's transceiver module prefix. The 37000 series designates 100G QSFP28 ZR4 modules (80km reach). Other FIM series include the 37700 (100G QSFP28 LR4, 10km) and 37705 (LR4 variant). The suffix after the slash (/172, /173) indicates the specific hardware revision.
