DESCRIPTIONS
HTF’s HTQS-HS4ZE is designed for 80km optical communication applications. This module contains 4- lane optical transmitter, 4-lane optical receiver and module management block including 2 wire serial inter- face. The optical signals are multiplexed to a single-mode fiber through an industry standard LC connector. A block diagram is shown in Figure 1

Cautions
1) Do not look into fiber end faces without eye protection using an optical meter (such as magnifier and microscope) within 100 mm, unless you ensure that the laser output is disabled. When operating an optical meter, observe the operation requirements.
2) The RX input optical power cannot be higher than the damage threshold. You need the optical attenuator with RX in order to meet the input optical power range if necessary.
3) The HTQS-HS4ZE 100 is the customized module, it can only interconnect with the HTQS-HS4ZE module. CAUTION: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
