This document describes a logic interface laser transmitter for OC3/STM1 with a transmission rate of 424 155 Mb/s. The product is SONET/SDH compliant and can operate in the temperature range of -40°C to +85°C. It features an ECL/PECL logic interface and is suitable for applications such as single mode ATM, fiber to the home, and data communications networks.
The XMT5170-155 is a high‑performance, uncooled optical laser transmitter for SONET/SDH and ATM applications. It features an ECL/PECL logic interface, a compact 20‑pin DIP package, and optional laser disable input for standby or test modes. The device includes analog outputs proportional to laser current and optical power for monitoring end‑of‑life or over‑temperature conditions.
Performance specifications include a supply voltage of 4.75‑5.5 V, center wavelength 1280‑1335 nm, average output power –5 dBm to 2.5 dBm, and rise/fall times of 2 ns. Ordering options provide FC/PC (FP) or ST (ST*) connectors and temperature grades A (‑40 °C to +85 °C) or B (0 °C to +70 °C).
| Supply Voltage | 4.75‑5.5 V |
|---|---|
| Center Wavelength | 1280‑1335 nm |
| Average Output Power | -5 dBm to 2.5 dBm |
| Rise Time (10%‑90%) | 2 ns |
| Extinction Ratio | 10 dB |
| Supply Current | 70‑130 mA |
| Operating Case Temperature (A grade) | -40 °C to +85 °C |
The XMT5170-155 operates from –40 °C to +85 °C for the A temperature grade and from 0 °C to +70 °C for the B grade.
The device can be ordered with FC/PC (FP) or ST (ST*) fiber connectors.
The Transmit Disable pin must be biased within 3 V of Vcc to disable the laser; if left open, the module remains enabled.
