PRODUCT PRESENTATION
The PHILISUN SFP+ 16G CWDM (1470-1610nm) 10/40km LC DX series single-mode transceiver is a compact, pluggable module designed for serial optical data communications, such as 16x/8x/4x Fibre Channel applications. This module is optimized for single-mode fiber and operates at nominal CWDM wavelengths from 1470nm to 1610nm, with 20nm steps between each wavelength. It offers a guaranteed optical link budget of 14dB. Featuring an SFP+ 20-pin connector, the module supports hot-plug capability. The transmitter uses a CWDM EML laser, compliant with Class 1 laser safety standards under IEC-60825. The receiver employs a PIN detector and a limiting post-amplifier IC for reliable signal reception. The SFP+ 16G CWDM (1470-1610nm) 10/40km LC DX series is fully compliant with the SFP+ Multi-Source Agreement (MSA) Specification SFF-8431.

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.
