Note The dual SC connectors on the optical XENPAK transceivers support network interface cables with

either Physical Contact (PC) or Ultra-Physical Contact (UPC) polished face types. The dual SC
connectors on the optical XENPAK transceivers do not support network interface cables with an Angle
Polished Connector (APC) polished face type.

The XENPAK transceiver connects the electrical circuitry of the module with the optical or copper
network. Table 3 lists the 10-Gigabit XENPAK port cabling specifications. Table 4 lists the optical
transmit and receive specifications for most XENPAK transceivers.

1. Minimum cabling distance for optical XENPAK transceivers is 2 meters according to the IEEE 802.3ae standard.

2. Requires a 5 dB 1550 nm fixed loss attenuator for distances less than 20 km.

3. Links longer than 30 km are considered engineered links; meaning that for distances up to 30 km, no special link design rules need to be considered.
Link distances beyond 30 km require that you verify the cable characteristics, especially the cable’s loss value.

4. When shorter distances of SMF are used, an inline optical attenuator (11 dB) must be used to avoid overloading and damaging the receiver.
