PRODUCT DESCRIPTION
QSFP+ transceiver modules are designed for use in 40 Gigabit
Ethernet links over single mode fiber. They are compliant with the
QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4. These transceivers are
focused for use in controlled environments such as data centers.
Digital diagnostics functions are available via an I2C interface,
as specified by the QSFP+ MSA. The optical transceiver is compliant
per the RoHS Directive 2011/65/EU.
Optical module also be called optical fiber module, the translation
should be transceiver module. The function of the optical module is
the photoelectric conversion, and the transmitter converts the
electrical signal into the optical signal. After the transmission
through the optical fiber, the receiving end converts the optical
signal into the electrical signal. QSFP is a kind of optical
module.
Optical fiber module classification: according to function:It
includes optical receiving module, optical transmitting module,
optical transceiver module and optical transmitting module
The 40GBASE QSFP+ (Quad Small Form-Factor Pluggable Plus) modules
offer customers a wide variety of high-density 40 Gigabit Ethernet
connectivity options for data center, high-performance computing
networks, enterprise core and distribution layers, and service
provider transport applications.
