F-tone's QSFP-40GM-LR4 QSFP+ transceiver modules are designed for use in 40 Gigabit Ethernet links and 4x10G OTN client interfaces over single mode fiber. They are compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 and OTU3 C4S1-2D1 requirements specified in ITU-T Recommendation G.695. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP+ MSA. The transceiver is RoHS-6 compliant and lead-free per Directive 2002/95/EC, and F-tone Application Note AN-2038.

F-tone QSFP+ (Quad Small Form-factor Pluggable Plus) is a new Multi-Source Agreement (MSA) for high speed application, such as 40G-BASE, which provide four channels of data in one pluggable interface. Each channel is capable of transferring data at 10Gbps and supports a total of 40Gbps.

QSFP/QSFP+ Passive Electrical Loopback FTCQ-XLB is used for testing QSFP/QSFP+ transceiver ports in board level test. The electrical loopback provides a cost effective low loss method for QSFP/QSFP+ port testing. The FTCQ-XLB is packaged in a standard MSA housing compatible with all QSFP/QSFP+ ports.
