Fujitsu compatible FIM37700 Description
FIM37700 is Fujitsu’s part number for a 100GBASE-LR4 QSFP28 transceiver, used in the 1FINITY optical transport platform and the FLASHWAVE product line. EdgeOptic’s compatible replacement is built on our 100G-QSFP28-10 platform and ships with Fujitsu-recognized EEPROM coding. The module provides a direct functional replacement for the original Fujitsu optic in metro, regional, and enterprise optical transport network deployments where the client-side interface requires 100G connectivity over single-mode fiber.
The 100GBASE-LR4 specification uses four LAN WDM channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, each carrying 25G NRZ modulation for an aggregate data rate of 103.1 Gbps. The optical interface is duplex LC/UPC on G.652 single-mode fiber with a maximum reach of 10 km per IEEE 802.3ba. The module conforms to the QSFP28 MSA and supports DDM monitoring of per-lane Tx/Rx optical power, module temperature, supply voltage, and laser bias current. Operating temperature range is 0°C to 70°C.
Fujitsu’s 1FINITY platform is a disaggregated optical transport system where the T100 (transponder) and S100 (switch) blades accept pluggable QSFP28 modules for client-side 100G connections. The FIM37700 provides the LR4 client interface for connecting the 1FINITY node to local data center switches or routers over single-mode fiber. In metro transport architectures, the LR4 client optic bridges the short-reach gap between the 1FINITY chassis and the adjacent Ethernet/IP equipment, while the 1FINITY line side handles coherent DWDM transmission over longer distances. The FLASHWAVE 9500 series also references the FIM37700 for client-side 100G connections in legacy Fujitsu transport networks.
Fujitsu’s FIM-series part numbering applies to all 1FINITY-qualified pluggable optics. The FIM37700 is the 100GBASE-LR4 variant; other FIM numbers cover 100G SR4 (multimode, data center interconnects), CWDM4 (2 km reach, intra-campus), and additional wavelength/reach combinations for different client interface requirements. Fujitsu’s Virtuora Network Controller and the 1FINITY element management system both report transceiver DDM values for all installed QSFP28 modules, including per-lane optical power, module temperature, supply voltage, and laser bias current. EdgeOptic’s compatible provides identical DDM telemetry, ensuring full visibility into optical health metrics through Fujitsu’s standard network management toolchain.
EdgeOptic backs this compatible with a lifetime warranty and CE/RoHS certification. For 1FINITY deployment questions, bulk transport optic pricing, or platform-specific compatibility verification, contact our sales team
Frequently Asked Questions
Where does the FIM37700 fit in a Fujitsu 1FINITY deployment?
The FIM37700 is the client-side 100G optic. It connects the 1FINITY T100 transponder or S100 switch blade to local data center equipment (routers, switches) over single-mode fiber. The 1FINITY line side uses separate coherent DWDM optics for long-haul transmission over the metro or regional network.
What do other Fujitsu FIM part numbers cover?
Fujitsu uses the FIM-series for all 1FINITY-qualified pluggable optics. FIM37700 is 100GBASE-LR4 (10 km single-mode). Other FIM numbers cover 100G SR4 (multimode), CWDM4 (2 km), and additional reach/wavelength variants for different client interface requirements.
Does Fujitsu’s NMS report DDM for the EdgeOptic FIM37700 compatible?
Yes. Both the Virtuora Network Controller and the 1FINITY element management system read DDM telemetry (per-lane Tx/Rx power, temperature, voltage, bias current) from the QSFP28 module. EdgeOptic’s compatible provides full DDM reporting compatible with Fujitsu’s management interfaces.
Can the FIM37700 be used in non-Fujitsu switches?
The EdgeOptic FIM37700 compatible is coded with Fujitsu EEPROM specifically for 1FINITY and FLASHWAVE platforms. For use in other vendors’ equipment, order the EdgeOptic compatible coded for that specific vendor to ensure proper transceiver identification and DDM reporting.
