Optical Transmission Devices

To Customers Evaluating Optical Transmission Devices (Optical Transceivers, TOSA, and ROSA)

The speed of communications is increasing and delays are being reduced
by expanding the communications network of 5th generation mobile communications systems (5G).
Along with these technological advances, data traffic is growing heavier and the demand for large data centers is increasing.
Due to the expansion of optical communications networks between data centers, the demand for optical transmission devices has dramatically increased while technologies to increase the speeds of optical transceivers continue being developed.
ESPEC provides optimal products for reliability evaluations (Telcordia standards) and temperature dependency evaluations of optical transmission devices for which technological developments and market size continue to expand.

Temperature Characteristics Test System

Attenuation due to the length of high frequency electrical signal wires and bending of optical fibers has become a testing issue in the development of technologies to make optical transceivers faster. ESPEC provides a system that uses direct thermal conduction by heating/cooling plate. This allows high frequency signal wires to be as short as possible and eliminates bends in optical fibers.

  • Temperature Characteristics Test System Plate Heating/Cooling System
    • High frequency signal wires can be as short as possible and bends in optical fibers can be eliminated because specimens and measuring instruments are accessed on a flat table.
    Temperature range -40~150 °C
    Temperature uniformity ±1.5 °C(≦85 °C)
    ±2.0 °C(>85 °C)
    Plate size W210×D300mm

    * The above specifications are an example. Contact ESPEC for details.

  • Sliding tray type bench top chambers
    • A sliding tray is integrated with the door which makes it exceptionally easy to set up with measuring equipment and test samples.
    • The interface of the measuring instrument is located on the door, facilitating access to wiring. It means a shorter wiring length and contributes to improved measurement accuracy and signal transmission speed.
    • Best suited for evaluation of every small devices for 5G and IoT.
