Notes for LX4:
1. In some cases, customers might experience that a link would be operating properly over OM2 fiber type without
MCP.
2. Some customers may be tempted to connect 10GBASE-LX4 devices over MMF jumper cables without MCP
cables. This includes the case of links over OM3 cable for which the MCP should not be used. There is a risk to
overload and saturate the adjacent receiver causing high bit error rate, link flaps and eventually irreversible
damage. In such cases, a 5-dB attenuator for 1300nm should be used and plugged at the transmitter of the
optical module on each side of the link.
3. Another alternative for short reaches within the same location is to use a single-mode patch cable. There will be
no saturation over single-mode fiber. Please note the 10GBASE-LX4 devices can reach up to 10km over single-
mode fiber as per compliance to IEEE.
Notes for LRM:
1. With 10GBASE-LRM interfaces, a conditioned launch is preferred for applications over FDDI-grade, OM1 and
OM2. If no MCP is used, a MMF jumper cable of 2 to 5 meters long should be inserted between the transceiver
and the cable plant.
2. For customers using MMF jumper cables of any type to connect 10GBASE-LRM devices without MCP or
intermediate patch panels or connectors, it is preferable to measure the power level before plugging the fiber
into the adjacent receiver. When the power is measured to be above 0.5dBm, a 5-dB attenuator for 1300nm
should be used and plugged at the transmitter of the optical module on each side of link.
3. Another alternative for short reaches within the same location is to use a single-mode patch cable. There will be
no saturation over single-mode fiber.
