Dell (Force10) compatible 407-BBGN Description

EdgeOptic's 407-BBGN compatible is a Dell-coded version of the EdgeOptic 40G-QSFP-10 multi-vendor 40GBASE-LR4 transceiver. Dell catalogs this optic under both the ordering code 407-BBGN and the manufacturer part number WRJMF, so hardware stamped with either marking refers to the same module.

The module runs four CWDM lanes at 1271, 1291, 1311 and 1331 nm, multiplexed onto a single duplex LC over single-mode fiber for reach up to 10 km. A DFB laser drives each lane and a PIN photodiode receives, with per-lane launch power between −6 dBm and +3 dBm and receiver sensitivity of −12.6 dBm per lane. The 6.6 dB link budget covers a standard 10 km G.652 span with margin. Digital optical monitoring reports temperature, supply voltage, bias current, and per-lane optical power.

Dell lists 407-BBGN as a 40GbE QSFP+ LR4 interface for Dell PowerSwitch and Force10 networking. These are Ethernet switching platforms, so the optic carries 40GBASE-LR4 Ethernet and does not run OTN rates on Dell switching hardware. Confirm the exact platform and Dell OS release against Dell's transceiver compatibility documentation before deployment.

This optic is built to the IEEE 802.3ba Clause 87 40GBASE-LR4 standard and the QSFP+ MSA (SFF-8436, INF-8438i). It operates from 0 to 70 degrees C. The CWDM lane plan and duplex LC interface match the original Dell part, so it drops into existing 40G LR4 links without re-engineering the fiber path.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For volume pricing or qualification support, contact our sales team.

Frequently Asked Questions

Is Dell 407-BBGN the same part as WRJMF?

Yes. 407-BBGN is Dell's ordering code and WRJMF is the manufacturer part number for the same 40GBASE-LR4 QSFP+ transceiver. Engineers may find WRJMF stamped on the hardware and 407-BBGN on the purchase order; both identify this optic. EdgeOptic's compatible replaces either marking.
