PRODUCT PRESENTATION
The PHILISUN SFP28 25G 1310nm 10km LR LC DX is a high-performance single-mode transceiver designed for duplex optical data communications. Supporting data rates of 24.33Gbps and 25.78Gbps with CDR enabled, it also accommodates 10G Ethernet communications when CDR is bypassed. The module features an SFP+ 20-pin connector for hot-plug capability and provides digital diagnostic monitoring via an I2C interface.Equipped with built-in clock and data recovery (CDR), this transceiver operates at a nominal wavelength of 1310nm. The transmitter section incorporates a 1310nm multiple quantum well DFB laser, compliant with Class 1 laser safety standards (IEC 60825). The receiver section features an integrated InGaAs detector preamplifier (IDP) housed in an optical header, paired with a limiting post-amplifier IC for reliable performance.

Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor on the host board. Pull up voltage between 2.0V and VccT/R+0.3V. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 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 – 10 KΩ resistor. Its states are:
Low (0 – 0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled3) Module Absent, connected to VeeT or VeeR in the module.4) RX LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor. Pull up voltage between 2.0V and VccT/R+0.3V. When high, this output indicates the received optical power is below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.5) The module signal ground contacts, VeeR and VeeT, should be isolated from the module case.6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board.7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP+ connector pin. Maximum supply current is 360mA. Inductors with DC resistance of less than 1 ohm should be used in order to maintain the required voltage at the SFP+ input pin with 3.3V supply voltage. When the recommended supply-filtering network is used, hot plugging of the SFP+ transceiver module will result in an inrush current of no more than 30mA greater than the steady state value. VccR and VccT may be internally connected within the SFP+ transceiver module.8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board.
