FA-TCQ40LCW-10,CWDM Optical Transceiver 40GBase-LR4 QSFP Fiber Optic Transceiver 10km LC Duplex
The four channels SFP interface Quad Small Form-factor Pluggable
(QSFP) was born to meet the market demand for high-density and
high-speed pluggable solutions. The 4 channels pluggable interface
is with transmission rate of 40Gbps. Many mature key technologies
of XFP have been applied to the design of QSFP fiber optic
transceiver.
There are two basic interface specifications for QSFP+ optical
transceiver, they are 40GBASE-SR4 and 40GBASE-LR4. The former is
used in multimode applications, and the latter is used in single
mode applications.
The 40G BASE-LR4 QSFP+ optical transceiver conforms to the 802.3ba
standard and is used with LC fiber optic connector, and the
transmission rate can reach 40Gbps. The optical module has 4 data
transmission channels, each transmission channel has a transmission
rate of about 10.3125Gbps, and 4 channels can transmit data at the
same time to achieve 40Gbps transmission. The 40GBASE-LR4 QSFP+
fiber optic transceiver is usually used between the data center and
the Internet switching point, which is used with single mode fiber,
and the transmission distance is up to 10km.
The 40G LR4 QSFP+ optical transceiver is generally connected with
LC connector and the maximum transmission distance via single mode
fiber can be up to 10km. The optical module has four independent
transmitting and receiving optical channels. It is necessary to use
MUX or DEMUX to reuse and reuse optical signals. At the receiving
end, four channels with a transmission rate of 10Gbps will be
transmitted at the same time. When these serial data streams are
passed to the laser driver, the Directly Modulated Lasers (DMLs) is
used to control the wavelength. The optical signals modulated by a
direct modulated laser are then multiplexed and assembled together
on a single mode fiber. As soon as it reaches the receiver, the
transmitted signals are decomposed into four channels with a
transmission rate of 10Gbps. Then the PIN detector or mutual
resistance amplifier restores each data stream and then sends out
the light signal.
