This document provides technical descriptions, applications, and compatibility information for the Gigabit Interface Converter (GBIC), Small Form-Factor Pluggable (SFP), and 10 Gigabit Small Form-Factor Pluggable (XFP) optics modules in the Cisco® ONS product family.
Summary
Cisco offers a comprehensive range of pluggable optical modules for the Cisco ONS Family of multiservice platforms. The wide variety of modules gives you flexible and cost-effective options for all types of client interfaces. Cisco offers a range of GBICs for Gigabit Ethernet use, a wide variety of SFP modules, and has recently introduced XFP modules. These small, modular optical interface transceivers offer a convenient and cost-effective solution for an array of applications in the data center, campus, metropolitan-area access and ring network, storage area network, and long-haul network.

Technical Overview
SFP Module
The SFP transceiver module (Figure 1) is a bidirectional device with a transmitter and receiver in the same physical package. The module interfaces to the network through a connector interface on the electrical ports and through an LC termination connector on the optical ports. Electrical interfaces and dimensions are defined in the SFF-8472 industry-standard multisource agreement (MSA).

A schematic of the SFP transceiver module functional block diagram is illustrated in Figure 2. It contains three parts: the transmitter, receiver, and Electrically Erasable Programmable Read-Only Memory (EEPROM) storage chip. This block diagram is intended for information purposes only and does not illustrate design requirements.
Transmitter
In the transmit direction, the SFP transceiver module receives the electrical signal and transmits this data in an optical signal by using a laser driver that controls the laser diode. The optical output power is held constant by an automatic power control circuit.
Receiver
In the receive direction, the SFP transceiver module receives an NRZ optical signal and converts it to an electrical equivalent. The receive portion of the module will use some kind of amplifier to control the converted electrical signal.
EEPROM
This type of SFP transceiver is identified by the standard two-wire serial interface used in EEPROM with an I2C interface (with serial ID functions) that is part of the GBIC specifications and the SFF-8472 MSA. In addition, EEPROM offers an enhanced monitoring interface for optical transceivers as described in SFF-8472, which allows real-time access to the device to enable monitoring of received optical power, laser bias current, laser optical output power, etc.

GBIC Module
The GBIC transceiver module (Figure 3) is a bidirectional device with a transmitter and receiver in the same physical package. This transceiver converts serial electric signals to serial optical signals and vice versa. In networking, a GBIC is used to interface a fiber optic system with an Ethernet system, such as Fibre Channel and Gigabit Ethernet.

XFP Module
The XFP transceiver module (Figure 5) is a bidirectional device with a transmitter and receiver in the same physical package. The XFP module contains a 30-pin surface mount connector on the electrical interface and a duplex LC connector on the optical interface.
Figure 5. XFP Transceiver Module for the Cisco ONS Family
Figure 6 shows an XFP transceiver module functional block diagram. It contains two parts: the transmitter and the receiver.
Transmitter
In the transmit direction, the transceiver module receives a 10-Gbps electrical data signal and transmits the data as an optical signal via an E/O converter. The optical output power is held constant by an automatic power control circuit. The transmitter also contains a Clock Data Recovery (CDR) circuit. The function of this circuit is to attenuate and reshape any jitter received on the electrical interface.
Receiver
In the receive direction, the transceiver module receives a 10-Gbps optical signal and converts it to an electrical equivalent. The receiver contains a CDR circuit.

Pluggable Modules: List and Description
Cisco ONS Family modules have well-defined product IDs, making it easy for you to order the appropriate module.
The product ID is structured as follows: ONS-"AB"-"CCC"-"DD".
• A = S for SFP, G for GBIC, and X for XFP
• B = C for commercial temperature (0 to 70°C), E for extended temperature (-10 to 85°C), and I for industrial temperature (-40 to 85°C)
• CCC = Supported bit-rate or signal type: 155 Mbps for OC-12/STM-1 signal or 2 GF for a tri-rate Gigabit Ethernet, Fibre Channel, and 2G Fibre Channel signal support
• DD = Supported reach: S1 for short-reach/intra-office 1310 nm interface or SX for Ethernet
There are still some older product IDs for the Cisco ONS 15454 platform, but those IDs will migrate toward the newer ID scheme for the Cisco ONS Family.
Red color codes indicate deltas introduced with the 9.1 release.
