Description

The RQS-103G-LR4-LW QSFP28 optical transceiver is designed for 100 Gigabit Ethernet and 4×28 G OTN client interfaces over single-mode fiber.
It complies with QSFP28 MSA, IEEE 802.3ba 100GBASE-LR4, and ITU-T G.959.1/G.709 (including Supplement 39 – G.sup39).

Digital diagnostic monitoring (DDM) is supported via the I²C interface.
The module is fully RoHS-6 compliant.
