1. General
This document specifies the characteristics of the Small Form Factor optical
transceiver (Type:HTR6545) with LC duplex receptacle for an OC-48 Short
Reach interface (SR, up to 2km).
2. Function
This transceiver is powered from a single +3.3V power supply and operated at
a data rate of 2488.32Mbps(NRZ). Optical output power is held constant by
automatic power control over the specified operating temperature and voltage
ranges. Electrical data inputs and outputs have CML logic level.
The optical output is disabled by a TTL logic level input for that purpose.
A signal Detect (SD) output is provided to indicate the presence of an incoming
optical signal. SD is a TTL compliant signal. Received optical power, laser
bias current and laser monitor current can be monitored using pins for that
purpose.
Dimensions and pin assignment fully comply with MSA (Multi Source
Agreement) for 2 by 10 type optical transceiver.
3. Absolute Maximum Ratings
Stresses in excess of the ratings listed in Table 1 can cause permanent
damage to the device and affect device reliability. Functional operation of the
device is not implied at any condition in excess of those given in the operating
specification.
