Designation | Also Compatible With | Cable Type | Description | Wavelength | Distance | Speed | Notes |
PLR4 | LR | Singlemode | 40G breakout to 4x10G LR | 1310nm | 10km | 10G | See LR. QSFP+ |
CWDM | Singlemode | Coarse Wavelength Division Multiplexing | 1270nm to 1610nm | See ER, EX, ZR | |||
DWDM | Singlemode | Dense Wavelength Division Multiplexing | 1520.25nm to 1577.03nm | See ER, EX, ZR | |||
AOC | Multimode | Active Optical Cable | 1G/10G/25G/40G/100G | Direct attach > 5 meters | |||
DAC | Twinaxial | Direct Attach Cable | <5m passive, >5m active | 1G/10G/25G/40G/100G | This is not optical. | ||
T | Copper | 100m or less, depending on type | 10?/100M/1G/2.5G/5G/10G* | *Depending on model. This is not optical. Will often have speed in model#, such as 10BASE, 100BASE, 1000base, 10/100/1000BASE. 10G has a limited distance depending on cable type. | |||
LX | LH | Singlemode | 1310nm | 10km | 1G | ||
LH | LX | Singlemode | Long haul | 1310nm | 10km | 1G | |
ZX | Singlemode | 1310nm | 80km | 1G | |||
LR | Singlemode | Long Reach | 1310nm | 10km | 10G | ||
LR4 | Singlemode | Multiple | 10km | 100G | 4x25Gbps channels. There are some extended reach versions that can go 20 or even 30km. | ||
ER | EX, ZR (Match channel if you can - mismatch will work without a mux in an emergency, mismatched distance with ZR) | Singlemode | Extended Reach | 1550nm | 40km | 1G/10G | They can be baseband, CWDM, or DWDM. "Baseband" is typically a lower tolerance ~1550nm optic that is cheaper and not compatible with DWDM/CWDM channel plans. |
EX | ER, ZR (Match channel if you can - mismatch will work without a mux in an emergency, mismatched distance with ZR) | Singlemode | Extended Reach | 1550nm | 40km | 1G/10G | They can be baseband, CWDM, or DWDM.

BX | Singlemode | Bi-Directional Singlemode | Multiple | 10, 20, 40, 60 or 80km | 100m/1G/10G | Sends and receives on the same strand of fiber. Note that optics will come in a pairing, and may be designated upstream and downstream. Difficult to troubleshoot, muxing is preferred. | |
