LAN WDM 100G QSFP28 Transceiver 1310nm 10km DOM LC Single Mode
Arista QSFP-100G-LR4 Compatible 100GBASE-LR4 QSFP28 1310nm 10km DOM
LC SMF Optical Transceiver Module
Functional Description
This product is a 100Gb/s transceiver module designed for optical
communication applications compliant to 100GBASE-LR4 of the IEEE
P802.3ba standard and OTU4 4I1-9D1F requirements specified in ITU-T
Recommendations G.959.1/G.709 and Supplement 39(G.sup39). The
module converts 4 input channels of 28Gb/s electrical data to 4
channels of LAN WDM optical signals and then multiplexes them into
a single channel for 100Gb/s optical transmission. Reversely on the
receiver side, the module de-multiplexes a 100Gb/s optical input
into 4 channels of LAN WDM optical signals and then converts them
to 4 output channels of electrical data. The central wavelengths of
the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm
as members of the LAN WDM wavelength grid defined in IEEE 802.3ba.
The high performance cooled LAN WDM DFB transmitters and high
sensitivity PIN receivers provide superior performance for
100Gigabit Ethernet applications up to 10km links and compliant to
optical interface with IEEE802.3ba Clause 88 100GBASE-LR4
requirements. 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
