DESCRIPTION
l
l
l
l
The GBB-7440G series single-mode optical transceivers
meet the Gigabit Interface Converter (GBIC) specification
Rev. 5.5. It satisfies the optical interface specifications
defined in IEEE 802.3ah 1000BASE BX by using 1310 nm
transmitter and 1550 nm receiver. The transmitter section
uses a multiple quantum well DFB laser and is a class 1
laser compliant according to International Safety Standard
IEC 60825. The receiver section uses an integrated 1550 nm
detector preamplifier (IDP) mounted in an optical header
and a limiting post-amplifier IC. A PECL input / output
logic interface is used. TTL RX-LOS output simplifies
interface to external circuitry. A 20-pin SCA-2 host
connector is used to connect the converter to the host
system.

A sequence value of 1 indicates that the signal is in the first group to engage during plugging of a module. A sequence value of 2
indicates that the signal is the second and last group. The two guide pins on the connector are electrically connected to the transceiver circuit
ground. These two guide pins make contact with circuit prior to sequence 1 signals.

Serial module definition
protocol
Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, MOD-DEF(1:2) appear as no connector
(NC) and MOD-DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol. The protocol uses the
2-wire serial CMOS E 2PROM protocol of the ATMEL AT24C01A/02/04 family of components.
