Hamamatsu Photonics recently released several new ranges of optoelectronics products specially developed for the telecommunications industry. These products are designed For ATM and SDH applications, Gigabit Ethernet, IEEE-1394, fibre channel, as well as any other data transmission protocols.
Its latest range of products include low-voltage operation, high-speed InGaAs PIN photodiodes and InGaAs PIN with pre-amplifier. These are available in different styles and sizes (40 µm to 1 mm diameter active areas), working at the 1310 and 1550 nm wavebands. They operate from DC up to 3 GHz bandwidth with power supplies as low as +2 V (G8198 series).
For 1310 nm data transmission, Hamamatsu complements these receivers with matched FP laser diodes the L8231 and L8347 series. All the InGaAs and FP laser diode products are supplied in pre-aligned fibre-optic receptacles of various styles used by the industry, including ST, FC, FC-PC, SC, LC, MU, etc. These can be supplied pigtailed to a fibre-optic cable of the customer's choice, and terminated with any standard fibre-optic connector.
As a telecom components supplier, Hamamatsu says it fully understands the manufacturing requirements of the industry and has now introduced a specially designed UV spot cure system. This UV curing system offers higher UV output than most systems (to allow shorter curing times) and long lamp lifetime to reduce down-time and maintenance costs whilst in service.
