This product is a transceiver module designed for 2m-10km optical
communication
applications. The design is compliant to 40GBASE-LR4 of the IEEE
P802.3ba standard. The module converts 4 inputs channels (ch) 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 as
members of the CWDM wavelength grid defined in ITU-T G.694.2. It
contains a duplex LC connector for the optical interface and a
38-pin connector for the electrical interface. To minimize the
optical dispersion in the long-haul system, single-mode fiber (SMF)
has to be applied in this module.
The product is designed with form factor, optical/electrical
connection and digital
diagnostic interface according to the QSFP+ Multi-Source Agreement
(MSA). It has been designed to meet the harshest external operating
conditions including temperature, humidity and EMI interference.

Notes:
1. Even if the TDP < 0.8 dB, the OMA min must exceed the minimum
value specified here.
2. The receiver shall be able to tolerate, without damage,
continuous exposure to a modulated optical input signal having this
power level on one lane. The receiver does not have to operate
correctly at this input power.
3. Measured with conformance test signal at receiver input for BER
= 1x10-12.
4. MVertical eye closure penalty and stressed eye jitter are test
conditions for measuring stressed receiver sensitivity. They are
not characteristics of the receiver.
