Sumitomo compatible SQF0406L4LNGL Description

EdgeOptic's Sumitomo SQF0406L4LNGL compatible is a Sumitomo-coded 40GBASE-LR4 version of the EdgeOptic 40G-QSFP-10 multi-vendor QSFP+ transceiver. It is coded to match the Sumitomo SQF0406L4LNGL part for 40 Gigabit Ethernet links over single-mode fiber.

The module follows IEEE 802.3ba Clause 87 for 40GBASE-LR4, with four CWDM lanes at 1271, 1291, 1311 and 1331 nm multiplexed onto one duplex LC connection. It reaches 10 km over standard G.652 single-mode fiber and carries a 6.6 dB optical link budget. A DFB laser drives each lane between −6 dBm and +3 dBm, the PIN receiver holds −12.6 dBm sensitivity per lane with a +3 dBm overload point, and the module operates across the 0 to 70 °C commercial range. DOM provides live readings of temperature, supply voltage, laser bias current, and optical power.

Before deployment, verify the SQF0406L4LNGL part number and host platform against the Sumitomo compatibility documentation for the equipment in use, since a 40GBASE-LR4 QSFP+ qualifies per switch model and software release.
