Gigabit Ethernet circuit packs
Application packs
The following pack types are available:
• GE1/SX4
• GE1/LX4
• GE10PL1/1A8.
Cable data
Important! Only the fiber cables with listed comcode (see Engineering Drawings) are
allowed to be used, otherwise the proper functioning of the system cannot be
guaranteed.
The fiber types are:
• Multi Mode (MM)-minicord break-out cable (for SX applications)
• Multi Mode (MM)-simplex cable (for SX applications)
• Single Mode (SM)-minicord break-out cable (for LX applications)
• Single Mode (SM)-simplex cable (for LX applications).
OTES:
• Use only the Alcatel-Lucent provided MMF cable for the MMF application.
Otherwise the optical output power could be higher than specified.
• ZX applications always need a minimum of 5 dB attenuation between transmitter and
receiver. If optical loops are used (e.g. during tests) an appropriate attenuation is
required to avoid the damage of the receiver.
Connector data
LC connectors with an angled boot of 40-45 degrees are used for termination to port units
(beige connector for MM, blue connector for SM). The LC boot must remain freely
rotatable around the connector length axis after termination, in order to adjust its
orientation to the fiber routing direction without damaging the fiber.
GE1/SX4 and GE1/LX4
The following figure shows the layout of the GE1 circuit packs.
