2–6 MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
PRODUCT DESCRIPTION CHAPTER 2: PRODUCT DESCRIPTION
2.2.6 Module F, Module E (100 Mb) - (use in Slots 3-10)
Two SC Multimode or two ST Multimode
The Module F (shown) two-port fiber module provides two 100Mb Multimode SC Fiber
ports. This option utilizes a SC-type "push-pull" fiber optic connection.
FIGURE 2–5: Module F - Upper Port module (slots 3, 5, 7, 9)
FIGURE 2–6: Module F - Lower Port module (slots 4, 6, 8, 10)
The 10K2-MST two-port fiber module provides two 100Mb Multimode ST Fiber ports. This
option utilizes a ST-type "twist-lock" fiber optic connection.
The 100Mb Multimode SC and ST ports typically support fiber optic cable distances up to
the IEEE standard 100Mbps distance limits, typically 2km at full-duplex.
Each port has a Link/Activity (L/A) LED indicating proper connectivity (Link) with the remote
device when lit and blinking (Activity), indicating packets being received.
A module similar to Module E is also available with IEEE 1588v2 Timing Synchronization as
Module F.
2.2.7 Module J, Module L (100 Mb) - (use in Slots 3-10)
Two SC Singlemode
The Module J two-port fiber module provides two 100Mb Singlemode SC Fiber ports,
supporting distances up to 20km. This module provides the same functions as the
Multimode version (see Section 2.2.7 for more details).
The Module L two-port Fiber module provides two 100Mb Singlemode SC (Long Reach)
Fiber ports, supporting distances up to 40km. This module provides the same functions as
the Multimode version (see Section 2.2.7 for more details).
A module similar to Module J is also available with two SST (Singlemode ST) ports and IEEE
1588v2 Timing Synchronization as Module W.
2.2.8 Module N, (100 Mb) - four open 100 Mb SFP Slots (use in Slots 3-10)
The Module N four port module provides four 100 Mb open SFP ports, supporting distances
up to 40 km. This module provides the same functions as Module G (see Section 2.2.3 for
more details).
