The centralized Point-to-Point fibre access approach with a dedicated single mode optical fibre link connecting each customer to a Central Office (CO) has advantages regarding future-proofness, security, and simple and low-cost optical links and transceivers. The potential bottleneck in handling the large number of optical fibres that need to be terminated in the CO, and combined with optoelectronic components, has been studied within the IST 6 th Framework Programme integrated project MUSE. The key parts in the CO are the passive cabinet where customer fibres are accessible through fibre connectors in the Optical Distribution Frame (ODF), and the active cabinet with switching equipment and optical transceivers. For the passive cabinet we conclude, that the most efficient solution is that each connection from the active cabinet to a customer passes only one ODF, and that small form factor connectors are used. For the active cabinet we have demonstrated the feasibility of an SFF-size module containing two bi-directional transceiver units by building and successfully testing a prototype, increasing the customer port density by a factor of two compared to commercial transceivers. The power consumption, which impacts power supply, cooling and cost, has been analyzed, and we propose measures to significantly decrease the power consumption.

“…A Fabry-Perot laser diode (FP-LD) emitting 1.3-mmwavelength light is used in a bi-directional optical subassembly (BOSA) for optical network units (ONUs) in access networks. [1][2][3][4] A conventional BOSA usually consists of a wavelength-division-multiplexing (WDM) filter and two transistor-outline (TO) can packages; one used for the transmitter and the other for the receiver. Recently, a lowcost and compact BOSA that integrates a FP-LD, photodiodes, and a WDM filter in a TO-can package (one-can BOSA) has been developed.…”

“…Recently, a lowcost and compact BOSA that integrates a FP-LD, photodiodes, and a WDM filter in a TO-can package (one-can BOSA) has been developed. [2][3][4] To reduce the cost and power consumption, the FP-LD in the one-can BOSA is designed to operate at high temperature (85 C) without a thermoelectric cooler. A waveguide structure for narrowing divergence of the optical beam launched from the FP-LD is also introduced into the design of the LD to reduce the assembly cost.…”

Reliability of a Fabry-Perot laser diode (FP-LD) that was developed for use in the bi-directional optical subassembly of access networks was investigated. Stable operation, which was closely related to the wear-out degradation, was confirmed from the results of an accelerated aging test at 85 C, and a lifetime of over 2 Â 10 5 h was estimated. To examine the behavior of the wear-out degradation in the FP-LD, we employed an optical-beam-induced-current (OBIC) analysis. From the results of the OBIC analysis, we found that large degradation occurs in the SCH layer rather than in the active layer in the early stage of the FP-LD's life.
