40G Base-LR4 QSFP+ 20km Optical Transceiver
Description
This Transceiver is a high performance, cost effective module for serial optical data communication applications to 41.5Gb/s.The HC-QP-S31L-20D 4 is designed to 40GBASE-LR4 of the IEEE P802.3ba standard for 20km links.
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.
Features
l LC duplex connector
l Maximum power consumption 3.5W
l 4 CWDM lanes MUX/DEMUX design
l Operating case temperature: 0 to 70℃
l Up to 11.2Gb/s data rate per wavelength
l Up to 20km transmission on single mode fiber (SMF)
l Compliant to the industry standard SFF-8436 QSFP+ Transceiver Specification
