Description
F-tone Networks’s 40GE QSFP+ ER4 40km Optical Transceiver modules are designed for using in 40 Gigabit Ethernet and 4X10G OTN client interfaces over single mode fiber. They are compliant with the QSFP+ MSA, IEEE 802.3bm 40GBASE-ER4, and OTU3 requirements. The F-tone Networks technology enables the integration of 4 transmitters, 4 receivers and an optical MUX/DeMUX into a small form factor package
Features
● Hot-pluggable QSFP form factor
● Supports 39.8 Gb/s to 44.6 Gb/s
● 18.5 dB link insertion loss budget
● Single 3.3V power supply
● Maximum link length of 40km on Single Mode Fiber (SMF)
● Uncooled 4x10Gb/s CWDM transmitter
● XLPPI electrical interface
● Duplex LC receptacles
● 3.5W maximum power dissipation
● RoHS-6 compliant (lead free)
● Case operating temperature
Commercial: 0 ~ +70℃
Industrial: -40 ~ +85℃
Applications
● 40GBASE-ER4 40G Ethernet
● OTU3, OTU3e1, OTU3e2
Absolute Maximum Ratings
These values represent the damage threshold of the module. Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within Recommended Operating Conditions.
