Description
The T92-T ype 10 Gbits/s laser transmitters are designed for use in transmission systems and high- speed data communication applications. The trans- mitter operates at the SONET OC-192 rate, as well as, the ITU-T SDH rate of STM-64. The transmitters meet all present T elcordia Technolo- gies * GR-253-CORE requirements and the ITU-T G.691 recommendations (see footnote 7, p.4). The transmitters are also ideally suited for extended dis- tance data and networking applications. Manufactured in a 24-pin DIP assembly, the transmit- ter uses an hermetic MQW isolated 1300 nm DFB laser, an InGaAs PIN photodiode back-facet monitor and a GaAs laser driver IC. The transmitter requires a single power supply (–5.2 V or +5.0 V). Clocked operation can be enabled for those applications where jitter is critical. Pin information is listed in T able 1. * Telcordia Technologies is a trademark of Telcordia Technologies, Inc.

- Laser back-facet function is a customer-use option that is not
used during manufacture and for diagnostics.
- Laser temperature (°C) = (V

- This pin can be tied to ground.
- For single-ended operation, data signal must be on pin 16, and
22) must be 50 Ω terminated to ground.

- With VEE connected to –5.2 V , VCC must be at 0 V; With VCC connected to +5.0V , VEE must be at 0 V .
- Inputs are ac-coupled into an equivalent input impedance of 50 Ω.
- Single-ended or differential operation may be used. If the inputs are driven single-ended, the unused inputs (Clock and Data) must be 50 Ω ter-
- Clocked operation is normally enabled and only requires an external voltage to disable. For nonclocked operation, pin 5 must be tied to VCC .
- With clocked operation, the optical output changes state with the rising edge of the input clock signal. The skew is measured with the rising
edge of the clock centered in the middle of the data eye.
- The transmitter is normally enabled and only requires an external voltage to disable.
- This alarm will go active when the bias current to the laser has increased 50% or more from its beginning-of-life (BOL) value.
- This voltage is measured from Pin 3 to VEE and is converted to laser bias current with the ratio of 20 mV/mA.
- This voltage is measured from Pin 2 to VEE .

- The 10 Gbits/s mask has not been currently agreed to by the standards committee. Proposal is to use the 2.5 Gbits/s SONET eye mask test
scaled to 10 Gbits/s. The inner mask will be met, however, the outer mask will not be met. Table 3. Optical Characteristics
