Fibre-Lyte can support both short wavelength (850nm) and long wavelength (1310 nm) operation.
Uniquely, Fibre-Lyte supports long wavelength operation (1310 nm) in a lens free OSA.
However, there are many features of Fibre-Lyte products which make them the OSA of choice for many applications but especially those which demand optimum performance in harsh environments.
Low Power Consumption
Fibre-Lyte OSAs deploy VCSELs which are are the most efficient in terms of optical output power per input power. Further, Conjunct does use driver/TIA line ups which are also very efficient.
Fibre-Lyte is deployed in applications where very milliwatt of power consumed is of key importance. Fibre-Lyte solutions optimise signal integrity and high temperature operation but do NOT require additional power. Fibre-Lyte's design regime provides fully optimised performance at low power.
Fibre-Lyte gives Superior BER performance and signal integrity. The metallisation regime which Fibre-Lyte uses does allow ground planes to be strategically placed to give the optimum RF performance and negligible RF cross talk and hence LOWEST possible BER (Bit Error Rate).
BER performance is further enhanced by using flip chip assembly which reduces the effects of cross talk. The figures below show that Fibre-Lyte could be the best platform on which to support PAM4 modulation, particularly at 25G.
No-Compromise Thermal Design
Fibre-Lyte uses a 'metal on die' approach to thermal management. This approach is the most efficient and allows Fibre-Lyte to operate over a wide temperature range.
A heat spreader is mounted directly on to the opto-electronic devices and rapidly spreads the heat from these devices on to an appropriate heat sink.
All Fibre-Lyte designs are fully simulated by FEA as part of Fibre-Lyte's design verification.
Fibre-Lyte uses flip chipping. Flip chipping is a simple and effective means of attaching the devices on to the OSA carrier. There are several very important features which result from this technique.
The size of the Borosilicate carrier can be minimized, if needed.
Assembly time is shorter because there are no multiple wire bonds attached.
Cross talk is minimized because there are no wire bonds. Minimal cross talk is essential to give superior performance at higher data rates or with PAM4 modulation regimes.
Using waveguides processed into the carrier means that there are no lenses used so there is no resultant beam expansion with its resulting cross talk issues. In addition, there are no air gaps which can be problematic in particularly dirty atmospheres. Furthermore, there are fewer parts in the OSA which is an important factor when used in harsh environments.

Hermetically Sealed (If Needed)
Fibre-Lyte can be hermetically sealed (at various levels) for a relatively low cost for ultra-sensitive applications.
