1541.34 nm C-Band Optical Source
The D2526Y45 operates at a nominal center wavelength of 1541.34 nm. This wavelength is located within the optical C-band commonly used for single-mode fiber communication, telecommunications component testing, and photonics research.
A defined center wavelength is useful when evaluating devices whose optical response changes with wavelength. Compatible applications can include testing optical filters, multiplexers, demultiplexers, couplers, switches, attenuators, receivers, detectors, and other C-band components.
The stated 1541.34 nm value identifies the specified center wavelength of this module. Applications requiring verified wavelength accuracy or current wavelength performance should measure the output with a calibrated wavelength meter or optical spectrum analyzer.
10 dBm Optical Output
The laser provides a specified optical output of 10 dBm. This corresponds to 10 mW of optical power.
This output level provides useful optical power for test paths containing patch cords, connectors, attenuators, switches, filters, and other passive components. It can also support insertion loss testing, receiver response evaluation, and single-mode transmission experiments.
The optical power delivered to a device under test can be lower than the laser output because of connector loss, patch-cord attenuation, component insertion loss, and the condition of the complete optical path. A calibrated optical power meter should be used when the delivered level must be documented.
An external variable or fixed optical attenuator may be required before connecting the source to a sensitive detector, receiver, or optical power meter. The maximum optical input rating of every downstream device should be reviewed before the laser is enabled.
Single-Mode Fiber Output
The D2526Y45 uses single-mode fiber for optical delivery. Compatible single-mode patch cords and components should be used throughout the optical path when consistent coupling and repeatable measurement performance are required.
Single-mode fiber supports controlled propagation of the optical signal near 1541 nm. This makes the module suitable for telecommunications test systems, component characterization, receiver testing, and laboratory transmission experiments.
The fiber should be protected from excessive bending, pulling, twisting, crushing, and mechanical strain. Tight bends or damaged fiber can increase loss and reduce the optical power available at the connected equipment.
FC/PC Optical Connector
The optical output is terminated with an FC/PC connector. Its threaded coupling mechanism provides a secure connection to compatible FC/PC single-mode patch cords and adapters.
FC/APC connectors must not be directly intermated with the FC/PC output. Angled and non-angled ferrules have incompatible end-face geometries and can cause excessive insertion loss, poor return loss, unstable measurements, or permanent connector damage.
The laser output and mating patch cord should be inspected and cleaned before each connection. Contamination can reduce delivered optical power, increase optical reflections, affect measurement repeatability, and damage both connector end faces.
Optical Component Testing
The TriQuint D2526Y45 can provide a fixed optical stimulus for testing compatible C-band components. The source can be connected to a device under test while an optical power meter, receiver, detector, or spectrum analyzer monitors the output.
This arrangement supports transmission measurements, insertion loss testing, receiver verification, and functional evaluation of wavelength-sensitive components. A suitable reference measurement should be established before the device under test is inserted into the optical path.
The D2526Y45 does not independently measure optical performance. A complete test system may require a calibrated power meter, variable optical attenuator, optical switch, reference patch cords, connector-cleaning equipment, and suitable control electronics.

Installation and Operation
The D2526Y45 should be installed only in a compatible mechanical, electrical, and thermal environment. The required power supply, current control, grounding, cooling, enable circuitry, and temperature regulation must be verified before electrical power is applied.
The laser module should not be connected directly to an unverified laboratory power supply. Incorrect voltage, polarity, current, pinout, or control settings can damage the laser assembly.
A clean FC/PC single-mode patch cord should be attached to the output. The cable should be routed with an appropriate bend radius and strain relief so that mechanical force is not transferred to the optical connector or fiber.
The connected equipment should initially be protected using suitable optical attenuation. The laser output can then be enabled while a calibrated optical power meter monitors the delivered level.
Connector Care and Optical Safety
The TriQuint D2526Y45 produces invisible infrared optical radiation near 1541 nm. The absence of visible light does not indicate that the source is disabled.
Users should not look into the FC/PC output, patch cord, adapter, or exposed fiber end. The laser should be disabled before optical connectors are inspected, cleaned, attached, or removed.
A clean protective cap should remain installed whenever the optical output is not in use. Only approved fiber optic inspection and cleaning procedures should be used on the FC/PC interface.
Comprehensive Functional and Performance Testing
The TriQuint D2526Y45 receives comprehensive functional and performance testing before shipment. When compatible drive and temperature-control equipment is available, evaluation may include electrical startup, thermal stabilization, output enable and disable operation, optical continuity, and basic source response.
Optical testing may include verification of output near 1541.34 nm, optical power near 10 dBm, short-term power stability, and spectral behavior using suitable calibrated measurement equipment.
The FC/PC connector, single-mode fiber, strain relief, housing, electrical interface, identification label, and laser-safety markings may be inspected for contamination, damage, corrosion, fiber stress, unauthorized modification, or excessive wear.
The exact testing scope depends on the available compatible laser driver, temperature controller, wavelength meter, optical spectrum analyzer, calibrated power meter, FC/PC reference cable, and required operating conditions.
