SFP 1G BIDI GOXS-BI4512-80D

Description:

GOXS-BI4512-80

SFP, BIDI, 1.25G, 1490/1550NM,

80KM, SMF, DDM

Overview

The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of

1.25Gbps/1.0625Gbps and 80km transmission distance with SMF. The transceiver consists of three sections: a DFB

laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All

modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement

(MSA) and SFF-8472. For further information, please refer to SFP MSA

Notes:
Plug Seq.: Pin engagement sequence during hot plugging.
1) TX Fault is an open collector output, which should be pulled up with a 4.7k-10k resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; Logic 1 indicates a laser fault of some kind. In the low state, the output will be pulled to less than 0.8V.
2) TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7k-10k resistor. Its states are:
Low (0 to 0.8V):
(>0.8V, < 2.0V):
High (2.0 to 3.465V): Open:
Transmitter on
Undefined
Transmitter Disabled Transmitter Disabled
3) Mod-Def 0, 1, 2. These are the module definition pins. They should be pulled up with a 4.7k~10k resistor on the host board. The pull-up voltage shall be VccT or VccR. Mod-Def 0 is grounded by the module to indicate that the module is present Mod-Def 1 is the clock line of two wire serial interface for serial ID Mod-Def 2 is the data line of two wire serial interface for serial ID
4) LOS is an open collector output, which should be pulled up with a 4.7k~10k resistor. Pull up voltage between 2.0V and Vcc+0.3V. Logic 1 indicates loss of signal; Logic 0 indicates normal operation. In the low state, the output will be pulled to less than 0.8V.
5) RD-/+: These are the differential receiver outputs. They are internally AC-coupled 100 differentia lines which should be terminated with 1000 (differential) at the user SERDES.
6) TD-/+: These are the differential transmitter inputs. They are internally AC-coupled, differential lines with 1000 differential termination inside the module
