Coherent launches I-Temp micro-pump lasers
Coherent Corp of Saxonburg, PA, USA, which provides photonics technology for communications and aerospace & defense applications, has launched its I-Temp micro-pump lasers for extended ambient temperature operation in broadband optical access networks.
The growing demand for broadband services is bringing fiber-optic networks closer to subscribers, with environmentally hardened equipment deployed in uncontrolled ambient environments where space is constrained and the availability of power is strictly limited, notes the firm. Coherent’s new I-Temp micro-pump lasers are now capable of operating over the extended temperature range of -40°C to 85°C, enabling optical amplifiers deployed at the network edge to withstand extreme weather conditions.
“The combination of small size, wide operating temperature, and low power consumption makes the I-Temp micro-pump a perfect solution for environmentally hardened optical amplifiers installed, for example, on utility poles,” says Dr Richard Smart, senior VP, ROADM business unit. “The I-Temp micro-pump leverages differentiated technology at every level of its vertically integrated design, including our gallium arsenide (GaAs) semiconductor laser technology platform, with its proven reliability through decades of field deployments.”
The I-Temp micro-pumps maintain a steady output power of 400mW with less than 2W of power consumption and remain optimally wavelength-locked with a fiber Bragg grating, without the need for an internal cooler. They are available with 80μm PM980 polarization-maintaining fibers and 125μm HI 1060 bend-insensitive single-mode fibers.
Coherent is exhibiting in booth #1 at the European Conference on Optical Communication (ECOC 2022) in Basel, Switzerland (19–21 September), showcasing the most recent additions to its portfolio of solutions for telecom and datacom optical networks.
