•Single-mode fiber (SMF)

•Multimode fiber (MMF).

Note: The estimated maximum transmission distance for OC-3c SMF is 20 kilometers (km); for OC-3c MMF is 2 km; for OC-12c SMF is 15 km; for OC-12c MMF is 500 m.

Point-to-Point Protocol

The PPP family of protocols is divided into three categories:

•Control protocols control operation and maintenance of the PPP link.

•Network protocols describe the encapsulation methods needed to move multiprotocol network traffic over the PPP interface.

•Network control protocols are used to configure, manage, and control the operation of the network protocols. The Passport 8683POS Module uses the Link Control Protocol (LCP) and the Link Quality Report to monitor the link.

PPP goes through the following basic initialization phases when bringing up links:

•Link establishment

•Network layer protocol

Establishing the PPP link

The Link Control Protocol (LCP) of the PPP helps establish a link. LCP generates three types of packets:

•Link configuration packets, including configure-request, configure-ACK, configure-NAK, and configure-reject packets

•Link termination packets, including terminate-request and terminate-ACK packets

•Link maintenance packets, including code-reject, protocol-reject, echo-request, and echo-reply packets

When two devices initialize a PPP dialog, each sends a configure-request packet to the other. Each configure-request packet contains a list of LCP options and corresponding values that the sending device uses to define its end of the link.
