General DeSCRJPTion
HTFuture’s QSFP+ LR4 is designed
to operate over single-mode fiber system using 4X10 CWDM channel in 1310 band
and links up to 10km. The module converts 4 inputs channel of 10Gb/s electrical
data to 4 CWDM optical signals, and multiplexes them into a single channel for
40Gb/s optical transmission. Reversely, on the receiver side, the module
optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to
4 channel output electrical data.
The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and
1331 nm. It contains a duplex LC connector for the optical interface and a
38-pin connector for the electrical interface. Single-mode fiber (SMF) is
applied in this module. This product converts the 4-channel 10Gb/s electrical
input data into CWDM optical signals (light), by a 4-wavelength Distributed
Feedback Laser (DFB) array. The 4 wavelengths are multiplexed into a single 40Gb/s data, propagating out of the
transmitter module via the SMF. The receiver module accepts the 40Gb/s optical
signals input, and de-multiplexes it into 4 CWDM 10Gb/s channels. Each
wavelength light is collected by a discrete photo diode, and then outputted as
electric data after amplified by a TIA.
The product is designed with form factor, optical/electrical connection
and digital diagnostic interface according to the QSFP+ Multi-Source Agreement
(MSA) and compliant to 40G QSFP+ LR4 of IEEE 802.3ba.
