Fujitsu compatible FIM37700 Description

EdgeOptic's FIM37700 compatible is a Fujitsu-coded 100GBASE-LR4 QSFP28 transceiver, built on the same 100G-QSFP28-10 hardware platform we use across the LR4 family. FIM37700 is Fujitsu's part number for this module, used in the 1FINITY optical transport platform and the FLASHWAVE product line. Our compatible carries Fujitsu-recognized EEPROM vendor identification so it presents to the host management system as a genuine Fujitsu optic during inventory polling and DOM telemetry.

Optically the module conforms to IEEE 802.3ba Clause 88. Four LAN WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm are multiplexed onto a single duplex single-mode fiber pair. Each lane carries 25.78125 Gbps NRZ for an aggregate line rate of 103.125 Gbps, which delivers 100 Gbps of net Ethernet payload after 64B/66B encoding. Secondary-market FIM37700/171 listings additionally cite OTU4 4I1-9D1F capability, which aligns with the module's role on Fujitsu 1FINITY optical transport equipment; verify the exact protocol mode required against the Fujitsu 1FINITY documentation for your line card before commissioning. The optical path loss budget is 6.3 dB, sufficient for 10 km of single-mode fiber with standard connector and splice losses.

QSFP28 MSA SFF-8665 and SFF-8636 management compliance covers the electrical and software interfaces. DDM/DOM telemetry exposes per-lane TX and RX optical power, module temperature, supply voltage and laser bias current. The duplex LC connector accepts standard SMF patch cords, and the commercial 0 to 70 °C operating temperature range covers typical central-office and data-center environments. Power consumption is rated 3.5 W typical.

FIM37700 is documented for Fujitsu 1FINITY platform deployments and carries forward into FLASHWAVE-line installations as a 100G client optic. Sub-variant ordering codes such as FIM37700/171 and FIM37700/172 surface in secondary-market listings; the suffix meaning is not decoded in the public Fujitsu material we located, so order whichever specific code your project documentation calls out. FIM37701 is a separate Fujitsu catalog number in the same module class; the exact functional difference between FIM37700 and FIM37701 is not documented in public Fujitsu sources, so do not treat them as drop-in equivalents without procurement verification.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing or specific Fujitsu sub-variant coding, contact our sales team.

Frequently Asked Questions

Where does the FIM37700 fit in a Fujitsu 1FINITY deployment?

FIM37700 is a 100GBASE-LR4 QSFP28 client optic used in the Fujitsu 1FINITY optical transport platform and the FLASHWAVE product line. The module sits on QSFP28 client ports and supports 10 km reach over single-mode fiber. Specific blade and slot placement varies by 1FINITY model (T400, T600, T700) and line-card revision, so cross-check the Fujitsu 1FINITY hardware documentation for the chassis and card you are commissioning before placing the order.

What do other Fujitsu FIM part numbers cover?

Fujitsu uses the FIM prefix consistently across its optical transceiver catalog. FIM37701 is a distinct catalog number in the same 100G QSFP28 LR4 product class; FIM37800 and FIM37000 cover other Fujitsu optic SKUs. The exact functional difference between FIM37700 and FIM37701 is not documented in the public Fujitsu material we located, so order whichever catalog number your project documentation specifies and do not treat them as drop-in equivalents without procurement verification.

Does Fujitsu's NMS report DDM for the EdgeOptic FIM37700 compatible?

EdgeOptic's compatible carries Fujitsu-recognized EEPROM coding, so it presents to Fujitsu management surfaces with the expected vendor strings. DDM/DOM values follow the SFF-8636 management interface and are exposed to the host platform; whether your specific NMS configuration (1FINITY element manager, FLASHWAVE NMS, or third-party platform) surfaces those readings depends on the NMS template and module-policy configuration. Verify DDM reporting against your NMS configuration before relying on it for production alarms.

Can the FIM37700 be used in non-Fujitsu switches?

Physically and optically, yes. The FIM37700 is a standard QSFP28 MSA module conforming to SFF-8665 and IEEE 802.3ba 100GBASE-LR4, so it interoperates with any IEEE-compliant 100GBASE-LR4 QSFP28 host port. The EEPROM vendor identification is Fujitsu, so a non-Fujitsu host platform will log the module as a Fujitsu optic in inventory but will not block it on standards-based hardware. If you need the module coded for a different vendor (Cisco, Arista, Juniper or similar), specify the target coding when placing the order.
