The GBS-7280-CXX0 series optical transceivers meet the
Gigabit Interface Converter (GBIC) specification Rev. 5.5.
It satisfies the optical interface specifications defined in
IEEE 802.3z Drift 5.0 for Gigabit Ethernet. There are
eighteen center wavelengths available from 1270 nm to
1610 nm, each step 20 nm. A guaranteed minimum optical
link budget of 24 dB is offered. The transmission distance
is depended on the wavelength and loss of fiber. The
transmitter section uses a multiple quantum well CWDM
DFB laser and is a class 1 laser compliant according to
International Safety Standard IEC-60825. The receiver
section uses an integrated InGaAs 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.
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It
complies with IEC-60825 and FDA 21 CFR 1040.10 and
1040.11. The transceiver must be operated within the
specified temperature and voltage limits. The optical ports
of the module shall be terminated with an optical connector
or with a dust plug.

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.

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
2
PROM protocol of the ATMEL AT24C01A/02/04 family of components.
