Laser Transmitter Modules for 10Gb/s and 8Gb/s SFP+
With its new transmitter optical sub assembly (TOSA) series Mitsubishi Electric
has developed four 1.3µm band laser modules for optical transmission at
speeds of 10Gb/s and, respectively, 8Gb/s.
Each individual module fits into an enhanced 8.5 and 10 Gigabit small form factor
pluggable module (SFP+) measuring just 13.3mm x 13.4mm x 56.5mm. Compared to
XFP (10 Gigabit small factor pluggable module) the SFP+ compliant transceivers are
60 percent smaller in width and 70 percent smaller in length. The new devices use a
Flexible Printed Circuit (FPC) for the electrical interface between the modules and
transceivers.
As this FPC is 80 percent smaller than comparable solutions the new module can be
installed in SFP+ compliant transceivers while simultaneously keeping the LC
receptacle package of the 10Gb/s miniature device (XMD-MSA).
By using highly-efficient distributed feedback laser diodes (DFB-LDs) for medium and
long-distance transmissions and fabry-perot laser diodes (FP-LD) for short-distance
communications, the new product can operate at currents of just 70mA, which is 20
percent lower than the current consumed by previous modules. This leads to a
decrease in power consumption as well as to an increase in operating temperature to
90 degrees C, which is 10 °C higher than before.
With these features the new TOSA series (FU-456RDF and FU-466RLD for 10G and
FU-442RDF and FU-443RLD for 8.5G transmission) from Mitsubishi Electric enables
the design of small transceiver systems. These are operating with low power
consumption over a wider temperature range which is essential features to achieve
high-density installations in fiber based applications like metro area networks and
high speed storage area networks.
