By Telecom Lead Team: GigOptix, a fabless provider of
semiconductor and optical components, has started shipments to Kaiam
Corporation.
Kaiam is a privately held company commercializing
photonic integrated circuits (PIC), of its HXR5104B, a quad Transimpedance
Amplifier (TIA) receiver array for 40Gbps QSFP+ applications.
GigOptix’s HXR5104B quad TIA is designed to be compliant
with the IEEE 40GBASE-LR4 standard meeting the exacting receiver sensitivity
and stressed eye requirements in addition to the 40Gbps QSFP+ form factor
needs.
The solution consumes less than 75mW/channel while
implementing the receive function of a 10km 40Gbps link. The quad channel
integrated design includes 4 high sensitivity 10Gbps TIAs, an industry standard
2-wire digital interface to enable the full control of the device.
The design minimizes the number of components required to
implement the 40Gbps receiver resulting in a lower cost and smaller form
factor. The HXR5104B further incorporates RSSI and based signal detect, among
other features, while the programmable preemphasis circuitry facilitates
optimal performance over various trace lengths.
“The HXR5104B is designed to provide a solution for
the challenging 40GBASE-LR4 requirements leveraging GigOptix’s deep expertise
in implementing parallel channel high speed low power solutions,” said Martin
Bossard, GigOptix’s Director of HX Product Line.
Ovum in its recent report on Optical Components report
stated that the 40G QSFP+ LR4 market would grow from 17 thousand units in 2012
to over 350 thousand units in 2016 with a Compounded Annual Growth Rate (CAGR)
of 111 percent.
Kaiam’s QSFP-LR4 Transmit Optical Sub-Assemblies (TOSAs)
and Receiver Optical Sub-Assemblies (ROSAs) enable 40Gbps links over single
mode fiber for 10km links. At a quarter of the size of 40Gbps CFP modules, the
QSFP is ideal for high growth datacenter, routing and switching applications.
We are pleased with the performance of the GigOptix’s
HXR5104B, allowing us an unparalleled combination of high sensitivity with
minimal cross-talk. The HXR5104’s versatility enables custom configurations
that can further optimize the performance of the link,” said John Heanue,
Kaiam’s Vice President of Technology Development.
