China Cheap price 25g Bidi - 25GBASE-LR SFP28 1310nm 10km Hi-Optel HSFP28-2321 module – Hi-optel Detail:

Descriptions

HSFP28-2321 is SFP28 module for duplex optical data communications support 25.78 Gb/s and 28.05 Gb/s data links. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. It has built-in dual clock and data recovery (CDR). This module is designed for single-mode fiber and operates at a nominal wavelength of 1310nm. The transmitter section uses a high performance 1310nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector pre-amplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.

Notes:
1.  Circuit ground is internally isolated from chassis ground. VeeR and VeeT may be internally connected within the SFP28 module.
2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
3. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 3.6V.
4. LOS is open collector output. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
5. Pulled low to VeeR or VeeT with a >30K resistor within the SFP28 module.
