Compatible Juniper QSFP+ LX4 Transceiver Introduction

---

In today’s data center communications,
individual streams routinely reach 10 Gbps speeds, and it is necessary to have
40GbE links to provide better performance. Such high-performance, high-density
40 Gbps network devices such as Juniper Networks switches, when equipped with
LX4 optics, seamlessly enable this transition. This article introduces Juniper
QSFP+ LX4 transceiver in details.

 

The Rise of 40 Gbps QSFP+ LX4
Technology

Short-reach (SR) and extended short
reach (eSR4) transceivers for 40 Gbps connectivity in a quad small form-factor
pluggable transceiver (QSFP) mode use independent transmit and receive
sections, each with four parallel fiber strands. For a duplex 40 Gbps
connection, eight fiber strands are required, while QSFP SR4 uses Multipath
Optical (MPO) 12-fiber connectors (MPO-12F). This IEEE standard technology must
reach up to 400m using OM4 and provide future support for 100 Gbps speeds using
the same cabling infrastructure. However, this technology requires more fiber
strands than can be found in today’s 10 Gbps infrastructures, which means that
data centers require a cabling upgrade. Juniper offers an innovative
alternative: a 40 Gbps QSFP plus (QSFP+) LX4 technology that allows for
zero-cost fiber migration by reusing the current 10 Gbps multi-mode fiber optic
(MMF) cabling plant for 40 Gbps connectivity.

 

Introduction to Juniper 40 Gbps QSFP+
LX4

Juniper offers a new 40 Gbps Ethernet
optical technology called LX4 and provides a QSFP+ 40GbE optical module that
uses the same infrastructure as 10GbE. The LX4 technology represents a new way
to deploy 40GbE that meets all of the performance criteria of today’s data
centers by providing 40GbE on two MMF strands and duplex LC connectors. The
Juniper QSFP+ LX4 transceiver addresses the challenges of fiber infrastructure
by providing the ability to transmit full-duplex 40 Gbps traffic over one
duplex MMF cable with LC connectors. In other words, the Juniper QSFP+ LX4
transceiver, a short-reach optical transceiver that delivers 40 Gbps over
duplex OM3 or OM4 MMF, allows 40 Gbps connectivity to connect directly to the
10 Gbps fiber and fiber trunk.

 

The Juniper QSFP+ LX4 transceiver has
four 10 Gbps channels, each of which can transmit and receive simultaneously on
four wavelengths over a MMF strand. The result is an aggregated duplex 40 Gbps
link over a duplex of two MMF strands. Using duplex LC connectors, QSFP+ LX4
connections can reach 100 meters on OM3 MMF or 150 meters on OM4 MMF.
