How to evaluate PLC Splitter’s quality is good?
1. Insertion loss(db)
Ai=-10lg Pouti/Pin
Ai=the first output port insertion loss
Pouti: the first output port Luminous power
Pin: input port Luminous power
Here is SURFIBER PLC splitter’s insertion loss(don’t include connector insertion):
| Type | 1*2 | 1*4 | 1*8 | 1*16 | 1*32 | 1*64 |
| Insertion loss | Typical | 3.6 | 6.8 | 10.0 | 13.0 | 16.0 | 19.5 |
| (P/S)Max | 3.8/4.0 | 7.1/7.3 | 10.2/10.5 | 13.5/13.7 | 16.5/16.8 | 20.5/21.0 |
| Type | 2*2 | 2*4 | 2*8 | 2*16 | 2*32 | 2*64 |
| Insertion loss | Typical | 4.0 | 7.0 | 10.5 | 13.5 | 16.5 | 20.5 |
| (P/S)Max | 4.1-4.3 | 7.4/7.6 | 10.8-11.0 | 14.3-14.5 | 17.3-17.5 | 20.7-21.5 |
2. Additional loss
Here is SURFIBER 1*N PLC splitter’s additional loss:
| Branch number | 2 | 4 | 8 | 16 |
| Additional loss(db) | 0.2 | 0.4 | 0.6 | 1.2 |
3. Splitting ratio
Depend on PLC splitter type (average or un-average type situation is different)
4. Insulation
SURFIBER PLC splitter insulation ≥40db
5. stability
Reliability and durability are up to the standard of IEC
